8 car bakerloos

Highgate was actually built for 9-cars because of the 9-car project on the Northern at the time.

yes, that's correct. The eventual plan was for 9-cars on the outside sections too and as the LNER stations were quite long anyway it was quite possible. Presumably if there was another New Works program certain stations in the central area would be 9-cars, avoiding the complicated arrangements that were implemented at Tottenham Court Road.

The 9-car train, after Golders Green, would stop so that the last two cars remained in the tunnel at each station. The Guard was in the 7th car so that he would always be in the station and he had a switch to cut the doors out.

At Tottenham Court Road, however, the first two cars stopped in the tunnel and the last two carriages could be used.

It started using Standard Stock but with the start of 1938 tube stock and the war it was less necessary and was withdrawn. This left extra DM and trailer cars, so these were reformed to make trains with the arrival of the 1949ts. These were used on the Bakerloo (so we are almost back to being relevant to the thread!)

The questions is, were these cars tipped out totally because no station south of there could accommodate 9-cars and what was the arrangement in the reverse?

Should have put this thread in the Northern Line board

'Tube Trains under London' contains details about the opperation of 9 car trains on the northern. Page 73-4. Well worth a look imho.

There was thought at the time of increasing the Bakerloo's capacity by running 8-car trains of Standard stock, but this would have required extension of all the Bakerloo platforms.

In the end, possibly because the Central tunnels needed reconstruction anyway to attain standard clearances, LT decided to extend the Central line platforms for 8 Standard stock cars, and the Bakerloo ran 7-car trains of 38TS.
