The Wikipedia article on the Genesis P-32AC-DM says there's a 10-minute limitation on third-rail operation. Can anyone help me understand why?
My understanding has always been that diesel-electric locomotives are merely electric locomotives that carry a power plant around with them. Why would getting the motor current from a third-rail shoe rather than the generator bus be something only possible for a few minutes at a time?
I never heard of any time limitations on the FL9's run for many years by the New Haven (and successors) that switched to third-rail shoes so they could shut off the diesels for the Grand Central approach.
