London Tubes: Unexpected locations of underground trains

Unfortunately there wasn't anywhere convenient for me to stop to take a photo. The other odd thing about the line is the OHL a long way from any electrified service lines. https://goo.gl/maps/Q70Uo Swindon works had a short length of third rail at one time within a caged compound, not long enough to run but for powering up some Southern EMU's that were being worked on. I think it's the only section of track, anywhere, with both fourth rail and overhead electrification. I think that it's currently being used for both S stock and IEP testing. Anywhere is a big place, The Milan Metro whose line 1 is electrified with a fourth rail almost like the LU ones has its track shared by overhead powered trains which came later for other routes. Both systems are DC so it is much simpler than the UK AC -DC Mix. ICBW but wasn't one of the continental test tracks given a fourth rail to test some tube stock? But it could have been on a circuit with no overhead. Which stock would that be? The only tube trains built outside the UK for a very long time would be the extra Jubilee line 1996 stock, but I don't know if that was put on an Italian test track. With such a small order (four train sets and 59 trailer cars), I doubt that it was worth equipping an Italian track with a fourth rail electrification system. http://www.alstom.com/press-centre/2...ound-20030619/ |

The only tube trains built outside the UK for a very long time would be the extra Jubilee line 1996 stock That was probably the stock I was thinking of but as I said ICBW , The suggestion by Arthur Figgis that the third rail laid at Wildenrath was what seeded the idea is most likely. but I don't know if that was put on an Italian test track. With such a small order (four train sets and 59 trailer cars), I doubt that it was worth equipping an Italian track with a fourth rail electrification system. Wasn't the stock both original and later build constructed in Spain? Not sure if was actually built complete abroad or if it was bodies fitted out later like the 95 stock. The original orders were assembled by GEC-Alsthom in Washwood Heath (the old Met Cam works). By the time of the top-up order, that plant had closed, so they were built by Alstom, I thought in Savigliano, Italy, like the extra Pendolino order. But maybe they were assembled in Spain and I was getting confused with the Pendolino order? Wherever it was can soon expect another top-up order for updated 95TS trains for the Northern and Jubilee lines. |

Wherever it was can soon expect another top-up order for updated 95TS trains for the Northern and Jubilee lines. I imagine a few new trains will be needed for the new battersea branch on the northern, but why will the jubilee need new trains? The service is pretty frequent already, I can't see how they'll squeeze any more trains onto the line. -- Spud |
