I think a better comparison would be the running gear was evolved from the 1956 Pioneer III non-powered Coach that Budd hoped to sell as designed to the roads who were "stuck" with their passenger service. Guess what; "no takers".
The Pioneer III unpowered cars directly lead to the Pioneer III EMUs (89,000 lbs ready to run!), which lead to the Silverliner IIs. The SL gained 10,000 or so lbs from GE's phase-angle propulsion system, though the PIII's was somewhat undersized (They supposedly popped transformers - an issue the Brits had with their early 25kv stock, too), and had a not very sucessful right angle drive system (which really looks like it was ripped from the RDC).

FWIW, that's my scan of the promotional material. I could dig up the Westinghouse book on 'em and verify the propulsion statistics (the TM voltage seems wrong). Also, camshaft control? Hell no, it was Westinghouse Unit Switch, which was pneumatic contactors and supposedly ripped off of a post (or pre?) war LIRR MU. The thing was quite literally a DC EMU with a substation strapped to it. IIRC, the only concession was the Ignitrons shut briefly while the line breaker opened...
I love the 'citation needed', that comes right from Budd's documentation...
Finally, "I thought I saw somewhere", but cannot verify - therefore a RUMOR, is that the Pioneer III prototype non-powered car ended up in South America, but was landlocked when the rail system abandoned passenger train service and tore up tracks accessing it (sounds a bit like "Richard the Second" with Meigs Field).
Supposedly it was rebuilt into the first LIRR 'turbine car', thus beginning the US DOT's infatuation with wedging helicopter engines into trains, which only finally came to an end after the JetTrain predictably flopped hard.
