They took a body from a coach and put it on bogies (obviously more complicated than that!) but it didn't work.
At the risk of thread drift, it did work, or at the very least, it came to fruition. Class 140 to 144 trains (Pacers, as they're known) are still plaguing customers today on Northern Trains and I think a couple of other TOCs even now.
Is there any more news on the BA short-haul LGW reports? Seismic change if true.
