There weren't any interlocks on 62 stock, you've imagined it.
Huh? Interlocks in the guard's bell circuit came in with the 1938 stock.
No they didn't, I've worked on both 38 stock on the Northern, and 62
stock on the central, and neither have any interlock that interferes
with traction current when the doors are open.

So the trains could be driven normally even if all the doors were open?

I'm pretty sure I remember times when a train tried to move and the power
cut out because there were door issues.
