They also featured a Westinghouse propulsion system which was a disaster, and relied on early SCR technology (like the Westinghouse Metroliners). Supposedly, a motor flashover or two would destory a good chunk of the rectifier system, leaving you with one dead car. GE didn't go SCR (and GE *invented* the SCR) until the Arrow III cars - by then they were beefy enough.
GE's proposal was ignitron based. GE was offering dynamics and 25kv and 60hz compatibility, too. They would have basically been the same as the SL II/III system, though the dynamics added the required grids and also a single handle controller, like the later GE equipped LIRR units had.
I have a copy of GE's proposal somewhere. It's very interesting to see what might have been..
