The trailers mainly had one compressor, though, didn't they?
No, I think they all carried two compressors, but I'll happily be
proved wrong.

Not as built they didn't, I don't think.

Having reread Piers Conner's "The 1938 Tube Stock" I see that 69 Northern
Line trailers in 3 car units were fitted with two compressors in the 1949
programme. They were intended for use in single 3 car unit trains while 3
car units on other line others retained their original single compressor
as they were not intended to run alone in service. 4 car units all had
two compressors because NDMs had one as well as trailers.

I think the conclusion is that Northern City 1938TS was always run in 6
car trains at least from 1970 after the closure of the Park Junction link
and the stock was provided from Neasden as 6 car trains AFAICS.
