With the ever-increasing political rhetoric over freight carriage, and depot battles being fought elsewhere, it would be easy to overlook another area where policy and developers appear to be clashing over the issue of Freight routes – Redhill.
The BackgroundMost British Railways were built during the reign of Queen Victoria. During this effervescent and turbulent period of massive construction now known as “The Railway Mania”, lots of one-route railway companies bloomed briefly before coalescing into bigger companies – some never even operated a train before being taken in hand. These were the days of the great companies, bitterly fought competitions for passengers and freight and brightly coloured engines. It was the halcyon days of the London Brighton and South Coast, the London and South Western, the Great Western, the Midland and finally as a late comer, the Great Central.
After the First World War, this railway structure was exhausted, and consolidation loomed again in the forming of the grouping into the London Midland and Scottish, the London and North Eastern Railway, the Great Western and the Southern, but much of the shape of the nation’s network was set before 1900.
Redhill in Surrey played a full part in railway history. The two pre-grouping main-line railways that left London for Surrey, Sussex and Kent - the London and Brighton Railway (and its successor, the London Brighton and South Coast Railway (LB&SCR)) and the South Eastern Railway (and its successor the South Eastern and Chatham - shared the route from Croydon to Redhill by parliamentary decree. As with a similar arrangement north of the Thames when the Midland had running powers from Hitchin into the Great Northern’s Kings Cross, these arrangements were fraught with operational difficulties. Whilst the Midland subsequently built the London extension from Bedford to Saint Pancras, the LB&SCR built a line avoiding Redhill station altogether, known as the Quarry Line, still in use by fast trains today.
There were originally two Reigate stations at separate sites, an inconvenient arrangement for passengers changing trains. Both were named Reigate after the nearby town, as was the new station north of the junction opened on 15 April 1844. The station was rebuilt in 1858, when the present buildings on the southbound side were constructed. It was at that time renamed Redhill Junction, later shortened to Redhill by Sir Herbert Walker’s Southern Railway in 1929.
Redhill station now has three platforms. Platforms 1 and 2 - serving the up tracks - are an island on the northbound side, whilst platform 3 is on the southbound side serving the down slow line. There are two through tracks between the platform 2 and 3 tracks. All platforms are subdivided into 'a' (north end) and 'b' (south end). Today all platforms are of 12 car lengths and have access to all routes, although there is no access from either through track to or from the North Downs Line. Consequently, all traffic (including freight trains) from this direction must pass through one of the platforms.
It is, however, the lines operated by the South Eastern and Chatham Joint Railway that we need to focus on. They operated two routes through Redhill from London’s Charing Cross and Victoria to Dover and by a somewhat circuitous route from London Charing Cross to Reading.

The Dover route is these days better known as the Redhill to Tonbridge Line. It branches to the east at the southern end of Redhill station and, after 19 miles, joins the current main line, that largely replaced it, from London to Ashford to Dover at Tonbridge station. The old route had been sanctioned by Parliament in 1836 as part of the first rail route from London to Dover. Looking at the map shows its remarkably straight route across country, as serving the settlements en route was at that time a secondary consideration.
Passing the sight of the old steam motive power depot wedged between the branch and the LB&SCR line, it starts with an initial curve just outside Redhill where it passes over the LB&SCR bypass route, the Quarry Line that is in a tunnel. The Bletchingley Tunnel, about a mile and a half southeast of Bletchingley is just over half a mile long. At the "Crowhurst Spur" the line connected with the East Grinstead branch of the Oxted Line but this was lifted in the early 1970’s.
The line has been electrified (750 V DC third rail) since 1992 and carries a half hourly service from Tunbridge Wells running alternately to Horsham, for which reversal at Redhill is required and also to London Bridge via East Croydon.
The line from Redhill to Reading was built by the Reading, Guildford and Reigate Railway (RG&RR), opening in 1849. The stated objective of the company was to:
secure through traffic passing between the West, North and Midlands and the Channel Ports avoiding the congestion of London and thus saving time, distance and expense.
The line runs roughly parallel to the North Downs between Ash and Redhill. The South Eastern Railway which operated the line from its opening, ran passenger services on the line from Reading to London Charing Cross via Redhill and even today, the distances along the line are measured from the terminus of the former SER.
As can be seen from the Ordnance map all tracks funnel together in south of Redhill before heading north to London, just as their promoters intended over one hundred and fifty years ago. If by chance you were a passenger who wanted to travel from Ashford or Tonbridge to Guildford or Reading, you simply changed trains at Redhill.
For freight, wagons were to the delight of small boys shunted by small tank engines or if a full freight train was required, the locomotive and brake van at the ends of the train were swapped and the train could then continue. This arrangement matched market needs and for over a century everyone was happy.
Freight in the Channel Tunnel AgeThe building of the Channel Tunnel, however, prompted British Rail to look carefully at freight routes in and out of Kent. The lines from ROSELAND, as estate agents so prosaically describe the Rest of the South East, came under review as timetable planners grappled with the problem of integrating an expected glut of freight trains from Europe onto an already busy network. Their problem was made worse by the fact that HS1 was only a twinkle in the mind of Mark Bostock, a consultant at Arup, who argued in the early 1990s for the route eventually taken by the Channel Tunnel Rail Link, now renamed High Speed 1, over the Thames east of London, through Stratford and into St Pancras station.
Like all good heretics he was ignored. The then-nationalised British Rail had favoured a route through south London into Waterloo station. Mrs Thatcher’s views about any futher investment had no doubt been conditioned by the 80% cost over run on the main Channel Tunnel project. Mwmbwls’ first trip on Eurostar involved being pushed back into my first class seat (back in the long lost days of being able bill clients for travelling expenses) as we joined the TGV Nord north of Villiers-La-Bel-Gonesse and then slumping in the same seat as we diddly dummed in from Dollands Moor, under Mount Sydenham to Waterloo over the only piece of purpose built new track infrastructure that slipped through Mrs Thatcher’s net – the link from Linford Street Junction to Nine Elms Junction.
Elsewhere British Rail Planners had enjoyed success by linking up old pregrouping rival lines to create new travel opportunities and increase network connectivity at minimal cost. In Manchester, expensive plans for an Underground link from Manchester Piccadilly to Manchester Victoria had been rebuffed in the 1970’s, but traffic had continued to build on the network. The dream of linking the northern and southern rail networks in Manchester did not die. The Hazel Grove Chord, built by British Rail, between the former MR and LNWR lines opened in 1986 and allowed trains from Sheffield via the Hope Valley line to run through Stockport on the way to Manchester Piccadilly station. Whilst beyond Deansgate Station lay Ordsall Lane Junction and to its right two former goods depots belonging to the London and North Western and Lancashire and Yorkshire Railways stood cheek by jowl although they were not directly connected by rail. They were further testament to historic levels competition in the days of Cottonopolis. The Windsor Link was a new line from Windsor Bridge Junction on the former LYR line built through the two goods yards to Ordsall Lane on the former LNWR line at minimal expense. It allowed trains from Bolton, Preston and the North to run directly to Piccadilly station and on via the Hazel Grove Chord to Sheffield and the East Midlands. The link opened in 1988 and came into full use in 1989, with many trains packed to the gunnels ever since. (That is if trains do have gunnels).
A Link At RedhillHaving demonstated the concept works, other examples were sought and a link at Redhill was proposed to enable Cross Channel freight trains to be diverted out of the path of both Eurostar and Kent commuter trains on routes into London. If a chord could be built from the Tonbridge line to the North Downs line, freight trains could be diverted off the main line to London and diverted by Redhill and Guildford to Reading and thereafter to Bristol and Birmingham. As they say in the advert – Simples.
Unfortunately Channel Tunnel traffic did not build as the promoters of the Channel Tunnel had predicted. This was for a number of reasons. Firstly, the promoters of the Channel Tunnel systemically exaggerated the traffic figures in order to secure funding from Governments and Banks (financing costs overran by 140%). Secondly, Eurotunnel’s highly efficient Euroshuttle operation, together with United Kingdom policies on road tax and fuel kept road-freight viable. European rail operators also showed a marked reluctance to change operating practices, facilitating cross border operations. German ports put up a strong national case supported by public opinion to retain their share of the export market (a situation that persists to this day despite the efforts of the EU Commission). Faultering logistics hampered by illegal immigrant-induced disruption and dented freight confidence as well and, finally, loading gauge differences and tunnel operating and safety requirements restricted the rolling stock types approved for international operation.
All in all - and unsurprisingly - faced with all of these the scheme remained firmly in the "too difficult" box.
A Scheme RebornMore recently interest in such a link has, however, revived - but another snag has appeared. Whilst looking for the DfT papers in respect the proposed sale of the Dartford Bridge, we stwmbled across a DfT-commissioned study into ways
to address capacity constraints at the Dartford-Thurrock River Crossing.
The Study, published in April 2009, had the following objectives:
- To advise the DfT about the future requirement for crossing capacity across the lower Thames over 30 years to 2037. This should include an initial evaluation of what role other modes (e.g. light / heavy rail, bus) might play in any plans for new capacity, leading to agreed options for evaluation. The study should look at demand and the consequential impacts (environmental and economic) of meeting that demand with new infrastructure.
- To investigate what may be done to improve traffic flow through the existing Dartford Crossing in the short to medium term, known as ‘making better use’ of the Crossing. This work should take into account existing Highways Agency plans for the Crossing and the motorway network in the immediate vicinity.
- To make best use of available traffic models to help understand the nature of current demand at the Crossing, the likely evolution of that demand and the impact that various options might have.
The Study includes an assessment as to whether if another bridge was built, a rail link should be installed on the bridge, making it bi-modal. As part of this analysis Parsons Brinckerhofff had included a concise summary of all major freiight flows by rail to and from Kent:
Key origins and destinations for rail freight services in North Kent and South Essex
In terms of existing rail freight services to/from north Kent there are broadly four main origins and destinations of traffic, namely:
1. Isle of Grain
a. Thamesport deep-sea container terminal (maritime container imports and exports)
b. Foster Yeoman aggregates imports (via berth and terminal adjacent to Thamesport)
c. Brett aggregates imports (via berth and terminal near Cliffe).
2. Medway Towns
a. Scrap metal exports (via Sheerness)
b. Steel imports (via Sheerness)
c. Brett aggregate imports (via Ridham Dock)
3. Maidstone/Ashford
a. Inward flows of aggregates (from Mendips) to Allington, Hothfield and Sevington
4. The Channel Tunnel
a. Imports and exports by intermodal and conventional rail
The origins and destinations outside Kent occur due to the industrial and distribution centre concentrations that are generally found to the north and west of London. Consequently, the existing train services to/from Kent either originate from or are destined for the WCML and GWML. Within Kent, rail traffic utilises two railway corridors, which subsequently join in south London before crossing the Thames (via the West London Line) and connecting with the WCML and GWML. In terms of Thames crossing facilities, the only route where rail freight is able to cross the river in the London area at present is over the Chelsea Bridge in west London.
Freight route to/from the Isle of Grain and Medway Towns
From the Isle of Grain and Medway Towns, departing freight trains head in a westbound direction along the North Kent Line via Gravesend and Dartford, before joining the Bexleyheath Line at Crayford Junction. Trains then continue on the Bexleyheath line via Eltham and Blackheath, and after passing through Lewisham station join the Catford Loop line at Nunhead Junction in the direction of London Victoria (alternatively, trains can run via Sidcup to Lewisham). Trains then continue along the Catford Loop via Peckham Rye and Brixton then, just to the north of Wandsworth Road station, leave the Catford Loop at Factory Junction and take a chord which subsequently joins the West London Line at Latchmere Junction (passing beneath the Waterloo-Clapham Junction line). Trains then continue along the West London Line, crossing the Thames at Chelsea Bridge and passing via Kensington Olympia towards Willesden Junction station, before joining the WCML at Willesden Junction and the GWML via Acton Wells and Acton East Junctions. Channel Tunnel freight routes
The main route used by freight trains to/from the Channel Tunnel.
The main route used by freight trains to/from the Channel Tunnel and the West Midlands, North West and Scotland is via Ashford and Swanley in Kent. Departing the Channel Tunnel, trains use the Folkestone-Ashford Line to Ashford, before joining the Ashford- Swanley Line just north of Ashford International station. Trains then follow the mainline via Maidstone East and Otford before joining the Chatham Mainline at Swanley Junction in the London direction. Continuing along the Chatham Mainline via Bromley South, trains subsequently join the Catford Loop line at Shortlands Junction. Trains then pass via Nunhead Junction along the route to the WCML and GWML described above. Trains to/from the aggregates terminals at Allington, Hothfield and Sevington also use the Ashford-Swanley route.
The “common” part of the routes used by all freight trains to and from Kent is therefore between Nunhead Junction and Willesden Junction via Factory Junction and the West London Line. Both routes are shared with passenger services and these can be constrained by freight trains as a result of their slower acceleration and braking rates. In turn any increase in the number of stops or number of passenger trains will result in knock on effects. The LOL’s Imperial Wharf, West Brompton and Shepherd’s Bush station are route pollution choke points for freight trains.
Bidirectional signaling from Latchmere Junction to Mitre Bridge Junction relieves some of the pressure as does the loop at Kensington Olympia, but a step change in freight traffic would be difficult to accommodate. In essence all of Kent’s eggs are in the west London basket. Which would be fine as long as TfL don’t wish to put more Londoner’s eggs in the same basket. The Mayor has however indicated at MQT that as part of the Transport Strategy, he wishes to
expand LOL services and to create major transport nodes at Clapham and Willesden Junctions.
For reasons of operational robustness it would thus be to both London’s and Kent’s benefit, if some of these freight trains could be diverted away.
A Strategic Freight NetworkThis view is echoed in a recent DfT report
about establishing a strategic freight network published in September 2009
The report builds on the need defined in the 2007 Rail White Paper for a Strategic Freight Network (SFN). The SFN is defined as: "a core network of trunk freight routes, capable of accommodating more and longer freight trains, with a selective ability to handle wagons with higher axle loads and greater loading gauge, integrated with and complementing the UK’s existing mixed traffic network."
Gordon Petrash, Director of Intellectual Property at Dow Chemical stressed the importance of vision in putting together a successful strategy on the logical basis:
If you can visualise it, you can measure it, and if you can measure it you can manage it
The DfT report makes a decent stab at this by listing a number of "what the system will look like" criteria:
An ideal freight network would accommodate optimum sized freight trains travelling at appropriate line speed, without checks, over optimum routeing to commercially preferred timings. In practical terms this suggests that the SFN should:
Optimise the pattern of freight trunk routeing to minimise passenger/ freight conflicts. This may lead to fewer, higher capacity trunk routes/ diversionary routes but also to the definition of ‘new’ trunk routes. This would provide potential gains in reliability, environmental performance and operating cost savings.
Develop appropriate diversionary routes and implement a standard network-wide possessions regime, with general use of single line working (SLW), to provide 24-hour/365-day network availability.
Upgrade an optimised pattern of freight trunk routes to eliminate traffic conflict and pinch points. This may require construction or reinstatement of chords, avoiding lines, investment in grade separated junctions, etc.
Upgrade trunk freight routes to meet the requirements of traffic, which may include any (or all) of the following: measures to increase the number of freight train paths; provision for increased train length; increased loading gauge (including the longer term objective of securing a European gauge route from High Speed1 (HS1) to the North); increased axle-load; and infill electrification.
The SFN will continue to evolve over time to reflect emerging national and international logistics and freight network requirements. We should therefore consider safeguarding strategic disused freight alignments, etc
New SFN capacity, particularly on key intermodal routes, will be required to meet industry growth forecasts if this additional traffic is not to be forced onto the congested road network. Routes for consideration for early capacity enhancement are likely to include:
- Ipswich to Nuneaton (CP4 and CP5);
- The GN & GE ‘Joint Line’ (to be upgraded in CP4 as the ECML Peterborough to Doncaster via Spalding freight line, with possible further capacity enhancement in CP5);
- Stourbridge to Walsall and subsequently Walsall to Lichfield restitution;
- Southampton to WCML – possibly with upgrades to routes and/or examination of alternative routeing options to provide East-West Line (Oxford-Bedford with upgraded links to the West Coast Main Line (WCML) and MML;
- MML 4-tracking;
- Freight routes to Manchester Hub terminals including Trafford Park.
The DfT then goes on to task Network Rail:
As a key element in developing the SFN, the Department has asked NR to undertake two freight routing studies and recommend the preferred routes between London and the South-East, and the Midlands and North of England, and the enhancements necessary to accommodate rail freight activity forecast to 2030 (the ‘Routes to the North’ (RTN) study); and an optimal cross-London freight strategy (CLFS).
The RTN study will include advice on accommodating UIC GB+ gauge freight vehicles whilst maintaining passenger and station capability, and the incremental cost of providing this. The CLFS is being taken forward as part of Network Rail’s proposed London and South-East Route Utilisation Strategy (RUS).
The DfT then goes on to publish a draft map of routes it considers worthy of study.

We annex the map here – if you cannot make out the detail it is Appendix A on Page 18in the report. Hopefully you should be able to see the green line running in a straight line due east of Tonbridge. At Redhill the green line splits into two suggesting that the LB&SC route to Clapham Junction’s platforms 16 and 17, and then back on to the West London Line, might be considered. But it also shows the green line continuing across country to Guildford and Reading via the North Downs and Blackwater lines.
The principle advantage of this route is that apart from the 1,327 yard long Bletchingley Tunnel, there are no other tunnels from Tonbridge to Reading. This would greatly facilitate the works necessary to allow the carriage of larger ISO containers.
A number of other upgrades taking place elswehere in the country which would add synergy to any upgrade of the North Downs/Blackwater Lines. Reading station is being rebuilt with a series of flying junctions. A disused fly-under from the Blackwater line to the former goods yard already exists at the east end of Reading Station. The lines from Reading to Bristol, Cardiff and Swansea, Newbury and Oxford are destined to be electrified under the current plans for the Great Western Main Line. This would mean that subject to minor infill ( probably third rail) electrification from Redhill to Guildford and Ash to Wokingham it would be possible for trains to and from Kent and the Channel Tunnel to be electrically hauled. This would include the aggregate trains bound for Kent originating from Theale, just east of Newbury.
Any major works required to establishing the Tonbridge Reading link would, apart the Redhill chord, involve either loading gauge clearance work to allow 9 feet 6 inch containers to be carried or the easing of potential choke points such as Guildford.
Some resignalling of services may be required from Wokingham to Reading where traffic flows could be intensified by the addition of Airtrack operations to Heathrow. The route from Southampton to Birmingham via Baisingstoke, Reading and Oxford is already being cleared for larger container usage as part of an existing national programme to improve port access. The DfT report makes mention of using the yet-to-be-reopened line from Oxford to Bedford to access the also-to-be-electrified Midland Main line.
And So The ConclusionThis all sounds splendidly doable and it would nice to leave the story at this point with Network Rail and the DfT’s wheels of their research engines turning in Noel Coward’s words with an “oomalacka boomalacka whee”. However, the site of the Redhill chord - over which a railway has never run although it easily might - has attracted the attention of one the great beasts of United Kingdom retailing...
Tesco.
And thus a clash of veritable Titans has now been born...
