It will be because of the requirement that trains had to have at least
two compressors that dictated 6 car trains all the time.
Why? Each compressor car carried two compressors, therefore any unit
could operate as it's own train. Remember the ordinary 4 car 62 stock
sets on the Epping to Ongar route?
