I have talked to both Metro-North and Shoreline East engineers & mechanics. Other than the electrical design was not meant for their operating environment (unneeded automation was how it was worded).

M-N had an average of 9 days between failure IIRC, but SLE usually averaged 240+ days. Most likely it was the same mind-set problem the original RDCs had. On M-N you had Locomotive Mechanics and Engineers working on what they considered oversized Buses, whereas SLE hired Bus Mechanics and trained new operators to drive the SPVs.

Biggest general problem was combining an open brush generator head on the APU for powering HVAC & all electrical system needs, with electric fuel pumps on all 3 engines engines, at least one of the main engines should have had a mechanical fuel pump. So if the generator shorted because of snow or wet leaves, and the operator doesn't notice the flashing light for APU failure, they are now running the lights and fuel pumps on small NiCad batteries (the whole bank is not much larger than 1.5 regular 8VDC locomotive battery). Once the batteries are drained engines shut down, lights go off, the radio is dead and there is no way to restart the motors. Thus some unlucky person (maybe they were actually the lucky one, not being the one left to deal with the customers) had to walk to the nearest phone and call for a rescue engine to be sent to get them.

This is why they were rechristened to Seldom Propelled Vehicles (within the railroading world) from the original acronym Self-Propelled Vehicle for the year 2000 .
