Lots of details on Bradford Snell's charges. Cecil sums up with:
Now, you may or may not believe GM's professions of innocence concerning the holding company. But most authorities agree that trolleys bit the dust in LA and elsewhere not because of a conspiracy but because they were slow and inconvenient compared to autos, and in the long run just couldn't compete. Los Angeles is typical in this respect. It has neither the high population density nor the concentrated downtown necessary to support rail transit. The PE, which was owned by the Southern Pacific railroad, made a profit in only 8 of the 42 years it was in business under its own name. The problem was exacerbated by the fact that many PE lines in LA proper operated on city streets, and as more cars crowded those streets, service got progressively slower. (The average speed on the run to Santa Monica was only 13 MPH.)
FWIW.
Cheers,
Scott.
