With electro-pneumatic controls and brakes it seems the cars only needed Tomlinson couplers for MU operation, though the article doesn’t mention that potential.

True on the reason for opposition.  The cars even had a tap to isiolate the centre doorway and fold down seats over the step space.

However, I suspect the reference to 'electro-pneumatic controls' is probably just a reference to dead-man handles on the controllers.

They were (and still are) fitted with standard K35JJ controllers - the dead-man handles were removed in 1935.
