Yes and no.

Railcar 18 (and all constructed after it) was built to be capable of hauling a tail load for working the Lambourn branch. That tail load was, on occasion, an autocoach.

The 'drive system' for GWR autocoach working was a mechanical linkage (other systems were used on other railways - the LSWR one was certainly different) which allowed the driver to operate the steam engine's regulator from the cab of the autocoach. It was not compatible with working a diesel-electric driven vehicle.

One assumes that the Railcar 'ran round' the autocoach at both ends of the journey.

I believe these were diesel-mechanical with a fluid flywheel. Certainly not diesel electric.

Yes. There was certainly space to do that at Lambourn and Newbury. Incidentally, there's a photo somewhere of a railcar at Lambourn with both an autocoach and a clerestory coach as the tail load.

Yes, I had the feeling the feeling as I typed it that it was wrong, but I couldn't think why.

I had a look for that photo out of curiosity and you can find it here. Interestingly, there’s also one of the railcar pulling a set of horse boxes.
