91 trains are needed in the peak Depots are at Golders Green, Morden, Highgate (aka East Finchley) and a little one at Edgware staffed by Golders Green Drivers. Trains can transfer to the Piccadilly Line Via the Kings Cross Loop but this is only used by Engineers Trains Now Forgive me for pointing this out Londonboy, but these questions have already been answered, and in any case this thread is almost a year old. I did see that the questions had been answered but i thought i would provide the correct info as i work on the Northern Line. I Thought if a topic was closed it would be locked, Sorry I will only reply to recent posts from now on in

Lol, shows how much looks can be decieving. I mean, take the District Line for example. Amazing how a lick of paint can make something look 40 years younger ;D ;D ;D ;D The District Line's D-stock isn't even 40 years old - first one arrived in 1981 I think (despite the 'D78' name) so that makes the oldest one 27 They were actually around in Summer 1979 as i remember our Picadilly Line trains running alongside them on our trips to Heathrow (went there 3 days in a row looking for standby flights).

How many trains can the siding at Tooting Broadway take? Also can the driver leave the train in the siding to, for example, walk back to the platform and go to the toilet in the main part of Tooting Broadway Station?
Also, i remember as late as the mid 80s when some trains from Tooting Broadway went to Mordern without stopping at Colliers Wood and South Wimbledon (passengers were told in advance). Was this because the trains were late but yet needed to go beyond Morden Station into Mordern depot?

Why did South Wimbledon Station used to show as South Wimbledon [Merton]? (one of the signs still shows it). Was this to distingush it from Wimbledon Station, about a mile away on the District Line?

Why did South Wimbledon Station used to show as South Wimbledon [Merton] underneath? (one of the signs still shows it). Was this to distingush it from Wimbledon Station, about a mile away on the District Line? Goes back to when the Morden extension opened in mid 1920s. The station wasn't in Wimbledon but in Merton (and was shown on some maps when under construction as Merton Grove) but the more upmarket name South Wimbledon (Merton) was eventually selected. The suffix was later dropped. There seems to have been quite a lot of changes to names on the line extension as Nightingale Lane became Clapham South just before opening, Morden was going to be Morden North (when the line was going to continue past the depot to Morden South (on what became the Wimbledon-Sutton Line which opened about 3 years later), Trinity Road later became Tooting Bec. The Wimbledon-Sutton Line was originally a District Line extension but became a Southern Railway build under an agreement as part of the Northern Line extension (the agreement also forbids futher extensions of Northern Line in South London without at least a years notice to Southern Railway or its successors, something that could now scupper the proposed Stockwell - Nine Elms - Battersea extension unless the clause is bought out)

I also read that another possible name for Clapham South was Balham North and with Clapham North it was Clapham Road.

When will the 95 stock trains be ungoverned? I believe they've been restricted at 60% power since new, due to the signaling that first needs a full upgrade throughout the line.
As they are now, they're a bit sluggish on pullaway in comparison to the Jubilee, Victoria, Central and Croydon tram stock.

As they are now, they're a bit sluggish on pullaway in comparison to the Jubilee, Victoria, Central and Croydon tram stock. The line speed will be increased on the Northern when TBTC is introduced. There will be some track improvement works, but the biggest amount of speed improvement will come from taking advantage of the current track / tunnel alignments without having to take into account the speed limit imposed by the current signalling's calculated overlaps. The line's new highest speed, which will apply in a number of different places, will be 96km/h and this is currently being worked into the SelTrac Safety Distance calculations for inclusion in the VCC data

The Northern line trains power restriction is not for signalling limitations, but for power supply. the existing transformers, circuit breakers and feeder cables date from the 1938, 1956, 1959 trains era. The old insulation would break down and overheat leading to electrical fires if you increased the current through them to the max amps new trains could draw.

Jubilee, Central and Victoria trains Pull away quicker as they're controlled under TBTC and ATO Thanks on that! But what does TBTC mean? Is that something to do with them being part automated like with the 67 stock that were on the Victoria Line? I'm not as clued up on the tube side of TfL.

Even the jubilee lines trains are restricted to 70% and that's the newest line They're pretty quick on 70% power. Were they always restricted or was it a recent thing? Also, aren't Swiss Cottage and St Johns Wood old a lot older than the other 'underground' stations on the Jubilee Line? They look as old as Colliers Wood and Tooting Broadway Stations on the Northern Line. I used to think it was a completely new line but later learnt that Baker Street to Stanmore was once a Bakerloo Line branch until sometime in the 70s.
