Network Rail officially started construction at Blackfriars station yesterday, marking the milestone with a rather traditional ceremony.
With the Lord Mayor looking on, a bundle of straw was lowered from the bridge and suspended above the river - something that, under the old river byelaws, was required in order to demonstrate to river users that there may be restrictions on using that particular arch:
When the headroom of an arch or span of a bridge is reduced from its usual limits but that arch or span is not closed to navigation, the person in control of the bridge shall suspend from the centre of that arch or span by day a bundle of straw large enough to be conspicuous and by night a white light.
Sadly the current rules are, of course, slightly more mundane:
When the arch or span of a bridge is closed to navigation the person in control of the bridge shall suspend from the centre of that arch or span -
(a) By day, three red discs 0.6 metres in diameter at the points of an equilateral triangle with the apex downwards and the base horizontal;
(b) By night, three red lights in similar positions to the discs displayed by day.
(2) When the headroom of an arch or span of a bridge is reduced from its usual limits but that arch or span is not closed to navigation, the person in control of the bridge shall suspend from the centre of that arch or span by day a bundle of straw large enough to be conspicuous and by night a white light.
And I suspect that it is these that will be observed going forward, unless there is a particularly strong Straw Lobby within Parliament of which I'm currently unaware.
[UPDATE: The straw requirement is still actually on the books - I've expanded the above quote to show it. Looks like that Straw Lobby is indeed stronger than I thought. Thanks to the Anonymouses for the spot - JB]
The station rebuild is, of course, one of the key construction projects currently underway on the network. When completed, the new station will be the first to span the Thames and the first to provide new access to the South Bank in a century.
Obviously there is currently a great deal of disruption at the station, although the new temporary riverside entrance - which opened back in April - is a surprisingly useful addititon. Ultimately, however, it should hopefully all prove worthwhile when the project is finally completed.



Thanks to RB for the spot.
The current regulations still call for exactly the same bundle of straw, it's in the most recently issuef byelaws and everything.
ReplyDeleteIt's definitely still 'straw' by day in both recent practice, and under the current byelaws - unless actually closed completely. So this isn't some sort of quaint throwback - it really is what they do normally.
ReplyDeleteThat's 'straw' of course - which is not the same stuff as 'hay', but wouldn't be as snappy a headline...
Really?! Blimey!
ReplyDeleteI've added an update the piece.
Thanks for that - I think you can probably guess what random fact I'm going to be boring people with down the pub later...
And yeah - I'll admit to indulging in a bit of creative licence on that headline.
ReplyDeleteAlthough if anyone can think of a suitable Straw pun, I'll happily change it!
I'm not sure if it's been linked on this blog before, but this presentation has some very nice diagrams of the Blackfriars rebuild (found by Paul Scott, not me)
ReplyDeleteSomeone once told me the "bundle of straw" came abut because barges of straw were the vessels stacked highest and so in an arch with restricted headroom the top of the pile of straw would embed itself on the obstruction, marking the obstruction with the straw left behind. This then turned into a bundle...
ReplyDeleteI expect the truth is that hitting some straw on a rope will give you a shock but not damage your boat...
Anyway, straw is also in evidence at Barnes Bridge where major repairs are starting from some impressive temporary decking. I heard a rumour that plans to shut the Bridge footpath for several weeks at a time over the next few years are being quietly shelved after locals dug out the original Act granting development rights for the bridge, which includes the need to have the path open. Anyone here know any more?
Nice article. What it omits to explain is why 4-VEPs are also included as part of Thameslink 10000, if the images from the project puffery which you reproduce are to be believed?
ReplyDeleteAnd I'm not John's mum.
I find it quite amusing they're still using slamdoor stock in the renderings!
ReplyDeleteI love the use of an old slam door train in the second artists impression of the new station. Are these on the way back??!
ReplyDeleteYou could economise on straw if you just tied Boris upside down to the bridge ...
ReplyDeleteI remember straw under the wobbly bridge a few years ago when it was being dampened.
