D stock samples Picc line

I'm not so sure that posting the train number is a good idea - a train number and a time bracket is more than enough to identify the T/Op, who may not want the whole intarwebnet to know that he took a wrong stick, whether by accident or on purpose.

Apologies, thread title altered. It did indeed go down the local and reversed via the depot. It then returned about 45 mins later via the e/b fast.

The reason why it used the e/b fast is because the e/b local is under a semipermanent engineering possession every day, all day, yet these possessions are never used.

You can only cross from the e/b local to the e/b fast east of Acton, using WL106 rte 2; if you want to cross from the e/b fast to the e/b local you have to use WL97 rte 1 west of Acton.

It was last used in 2003; the Piccadilly Line DEV shows a 1973TS in the e/b local platform at Northfields; the 64,000GBP question is whether or not that train was actually in passenger service.

I think soultrain told me once that there is at least one early-morning or late-evening 'rusty rail' working which acts as a functional test for the e/b local and the scissors crossover west of the e/b island at Northfields.

Thanks for that. Keeps the rails cleanish and keeps 'hands in'?

I wonder if this needs modification now? Do we have Train Nos. please for the scheduled workings please?

Updated thanks!

Gee, folks, anyone familiar with the track layout and signalling can understand what you are saying - the rest of us here gather a wrong stick was accepted or similar, and I guess there is a precedent for such a similar error already well recorded here :-)

Personally, my interest in clicking on this is over the former "mercury tubes" prevention protecting sub-surface stock from accidentally entering routes entering tube stock tunnels.
From other threads here I dare not refer to (at risk of being suspended again for a month or worst) as they have been dormant for at four weeks, I understand the protection I refer too is now conductive paint as Mercury is presumably a H&S hazard.

It brings up interesting points over the historical development of the LU signalling etc.... with the differing protection of overhead tubes to detect over-tube gauge stock in the Kensington area that could dent the Piccadilly tunnels, and the BR gauge stock in the Leyton area that relied on the Leyton Signal Box "electric detection" to clear the points for the Central Line New Works extension towards Stratford.

A further point arising above is the mention of "rusty-rail" working.

In my recollections of lurking on most posts on this entire Forum, I don't immediately recollect any questions re: "zig-zag"s that certainly in the 1960's, 1970's existed on trackwork that was occasionally used, to provide a "better" track circuit activation on "rusty rails".

As far as I recollect, these were quite common on LU trackwork, and especially I seem to recollect them on the sub-surface lines as well as the open-section tube tracks.

Well, to avoid accusation of going off-thread, I guess I'd better refer to the OP over accepting a wrong stick.

That (for the benefit of the Moderators) neatly ties in with my comments over signalling protection dating back at least some 50 years over covering out-of-gauge stock being signalled onto to potentially dangerous tracks.

Drivers or Train Operators or whatever you are called these days, are - if I am correct - trained to obey signals.

Red, you stop.

Green (OK, quoting the Highway Code) you proceed if in your opinion as Driver and Responsible for your Train it appears safe to do so.

So rather than as suggested in the first couple of posts here on this thread, a certain train driver might be subject to "ribbing" for taking a wrong stick, I am intrigued why no one questions why the oversight of setting the signals to permit an improper train to proceed along the selected route SHOULD NOT HAVE BEEN PROTECTED BY THE SIGNALLING SYSTEM ---
AND NOT JUST THE SIGNALMAN

Any comments anyone ?

From the Piccadilly DEV a SSL train can in theory reach Hounslow West, as the tubes are after the said station heading towards Heathrow. Train Ops are Humans as well and all humans are subject making mistakes it happens. From my understanding however the train nor it's occupants were under any danger as they were no where near a 'tube' tunnel.

The train simply took the scenic Route, and the poor T/Op will have a lovely tale to regale his staff canteen about.

Yes, Tubeprune can probably tell you more than I can but there were two iron or steel bridges that were to sub-surface gauge over Kingsley Road (Hounslow Town/Hounslow East) and Lampton Road (Heston-Hounlsow/Hounslow Central). You can see the original Lampton Road bridge here I believe:

The bridges were replaced so far as I know in an economical manner:

You can just about see part of the Kingsley Road bridge...trains used to "roar" across, and they were quote noisy!

Because presumably there was never going to be any SS stock using the branch as far as Hounslow Central, with the Heathrow loink being to tube gauge, the bridges were constructed to tube gauge as well and slid into position. SS stock is thus banned I gather west of Northfields though in theory could surely run to west of Boston Manor then shunt back into Northfields Depot? The last SS train that I know of was the D Stock Metroliner tour of 21st September 1980:

at Northfields 'local' EB, courtesy Solidbond. However in 1971 the Q Stock farewll tour reached Hounslow West, Platform 2 I think. I cannot for the life of me understand why the silver-paint tubes are still west of Central as SS stock would never have got as far as there!

Thinking about it now, I am sure that the Hounslow West tunnel ceilings which were cast for WC French (main contractors) are to tube gauge only as well.

Yes it's not the weight, per se, but the fact that they are narrower. So why in heck is there no SS train detector at Boston Manor west end or in the diveunder adjacent to Northfields depot WB or just after thereto?

TP did you ever get to drive down our way?

Apart from the A Stock and Sarah (L12) on brake block tests, Northfields also hosted both CO/CP Stock and R Stock on sand drag tests, late Seventies I think. They used to plonk them out of the way where the 1960 Stock TRC and the two 1973 Stock test trains were also parked, namely the rsiding adjacent to the access road into the depot.
