All the ones that I have run used the most common system of starting,
the main generator has a starter curcuit on the commontater and voltage from
the batteries is used to motor the diesel engine until it starts,
then when the start button is released,
the generator returns to its generating duties,
I cannot remember what it is,
but the older diesel electrics could be pushed by another locomotive and the
traction motors used as generators to turn over the main generator and start
the diesel if the batteries were not good enough to do it
I am not sure what you mean by modern and older,
the AC,
alternating current ones are different from the DC,
direct current,
the basic systems are the same,
the diesel electrics are actually similar to the electrics that get their power
from an overhead line,
instead of a diesel the accessories like the air compressor are run from an
electric motor,
your first generation diesel electics are just like later generations in main
systems,
there have been upgrades in air brakes and other accessories,
the main generator outputs are similar as the traction motors could be
interchanged if they would mechanically fit

start? Electric motor? Air compressor? 3 guys with a big rope?
What? Are modern ones the same as the old ones?
