‘09 Stock have Bombardier Mitrac LT201 three phase drive motors S Stock have the similar Bombardier Mitrac MJB_200-93 three phase drive motors As I thought, different motors as they clearly sound different and pull very differently. Even down to the speed the Vic line enters some stations and stops is highly impressive

The early tube lines were hampered as they had to run under the lines of the streets to avoid having to pay compensation claims to building owners. That's why the Central Line has the twisty bits in the Shepherd's Bush and Bank areas and why the Bakerloo curves so much. The Victoria and Jubilee Lines were not constrained in this way so could take a straight and direct line.

Thankfully the Stanmore branch's 1939 tunnels along the former Bakerloo/now Jubilee Line are straight enough to allow trains to dash as fast as they do in the newer sections...particularly eastbound from Saint John's Wood to Baker Street.

But they are different motors (in effect engines) It is like saying a Dennis Dart SLF with a Cummins ISB engine is the same as a Dennis Trident with ISC engine because they shared the same technology.

Hence why there's far more 'please mind the gap' announcements on the Central and Bakerloo lines than the Jubilee and Victoria. Speaking of which, is there really a need for this at every above ground station on the eastern end of the Central line and Bakerloo line. One thing I would like to see is the please mind the gap announcements to be updated at stations that need them, particularly Shepherd's Bush on the Central line, perhaps East Acton too.

Years ago in the 80's I only remember it at stations like Bank. It had a deep serious voice as well. Now almost every station has some warning.

CLIP 8-car Train 4 successfully made its own way, fitted with tripcocks, from Ruislip depot into Acton Works last night. (consist included unit 91109)

I sometimes feel they should mind the gap between the word mind and the remaining words the and gap.

I wonder if the central line is ever going to be extended to Uxbridge?

I always thought that the track width was a single UK standard. Didn't the Piccadilly and Central both operated 59 & 62 stock; so what has changed on the tracks since then.
