Back in LUL days, the ELL had a very distinctive smell. It smelt like tar or something - I never could quite workout what. However, this smell has now gone with the LO refurb! Does anybody know just what this strange smell was and why it has now gone?  |

It was certainly at Wapping (north end) last Thursday (but perhaps not so strong), along with the sound of running water!

The running water is still audible at one of it's other sations, too (I forget which one), but couldn't smell the smell. I haven't used Wapping yet, so I'll check for the smell when I next do so. |

Shadwell has running water. I was there the other day! The smell maybe the airbrake smell the A stock trains give off when using their Westinghouse brakes. The 378 don't make that smell  |

The 378 don't make that smell I was down there on Sunday and I have to confess that I noticed a smell. Hard to discribe, I thought it was the 378 braking system as it reminded me of that awful smell you used to get when HST/Mk3 stock was decellerating. It was very noticeable and quite strong. I'm there again this weekend so I'll keep an eye open (or should that be nose!) Martin |

I couldn't say that I smelt anything untoward when I was on the ELL last week. But if it's like a hot metallic smell, it's more than likely the brakes (especially new ones) getting hot with use. I like that smell...

Today at Wapping, around 12.30 -
"Very" distinctive "smell" (north end). Still can't identify what it is though.
Sounds of running water.
Pools of water on track at north end.

You can smell it a Moor Park sometimes as the fast trains come in to make a stop after 5 miles at 50mph!!  |

Today at Wapping, around 12.30 - Sounds of running water. Pools of water on track at north end. The sound of running water has always been a distinctive feature of Wapping (and indeed Rotherhithe) stations. Those of us who visited Wapping before the present,rather nice,artworks were installed,will recall the frighteningly narrow platforms bounded on the one side by the track,and on the other by brickwork so damp that parts were literally coated with flowing water,plants and mosses grew from the mortar where there was light enough,and a runnel along the back of the platform and the base of the retaining walls,took water steadily away. I was less familiar with the "old" Rotherhithe,but on the Tunnel open-day recently.the runnel in the centre of the four-foot was quite full of water,and the nice man said that there were THREE pumps at Rotherhithe backing one-another up in case of failure. Should failure occur,he said,the tunnel would flood,the water would overtop the platforms at Canada Water,a few feet down the line,and the Jubilee line would not only be put out of action,but would convey the waters into Central London,paralysing the tube network...... So three pumps ,then. |

Hmmm. This would require an interesting set of random calculations to verify - and that water would have to run uphill for seversl parts of it. I would (as a first approximate) suggest that all redundancy systems had failed with the pumps, there was a sudden and inexplicable failure of the shotcreting and the elder Brunel's brick arches, giving an opening of about 20' square....... Perhaps 23 minutes on an ebb tide, before any other lines than the ELL or Jubilly are affected. Further and progressive failure of the brick arch due to flow friction notwithstanding. I wonder what the actual answer is.... |

water would have to run uphill . Water often runs uphill - how do you think it gets to your bath taps? Anywhere below the level of the surface of the river is capable of being flooded. |

I think he was giving a "worse case scenario" for risk assessment purposes(!!)
The point he was making was that no catastrophic failure was necessary. The constant ingress of water on a daily basis was enough to cause a worry,which had to be planned for.
I think he liked the image of water tumbling down the escalators at Canada Water!!

I was inelegantly expressing the changes in gradient, and roughly calculating how long and how many gallons it would take the ripples to lap up towards London Bridge station - this is of course based on the catastrophic scenario. However, you've touched on something there, thinking of the Darcy-Weisbach Equation; some of the static head would be lost through Culling Road, Druid Street and then eventually Wardens Grove. Curious. ;D |

Well actually dependant on your house plumbing it could be flowing down from your water tank in the loft, thus it wouldn't really be travelling uphill to your bath taps then... Of course it is pumped under pressure to that tank.  The theory of the central network flooding is an interesting if albeit scary one. I read somewhere (Not sure where) that if one of the under Thames Tunnels was breeched during the war, then water would be flooding over Holborn's platforms literally within ten minutes (Strikes me as odd as Holborn isn't connected to a line under the river.) and the majority of Zone 1 would be flooded within an hour or so. Do the floodgates still work? ;D Cheers, ~ Gary |

Rather than having a ghoulish interest in the 'what would happen if' scenarios, my interest stems from the work of the signalling engineer Robert Dell - the final few pages of ' London Transport Railway Signalling - Papers on the Life and Work of Robert Dell 1900 - 1992' detail the hydrophonic recording room built in the deep level District at South Ken. This 'River Thames Sound Detection Scheme' was designed by Dell. This was a clever series of recording devices that would sense the sharp wave-front of a bomb landing in the Thames (the chug-chug-chug of a propeller would be automatically discounted by the machinery). The hydrophones were sensitive enough to detect a bullet fired into the river at Embankment!  All designed and installed by the Signalling Department. |

MRFS42 - from who else would I be moved to learn more about Henry Darcy, Julius Weisbach, Robert Dell, and the original Andrew Melville.
And to find it here at District Dave's Emporium of All Knowledge!
What a place!
