As I was describing the energy use, It takes a heck of a lot more energy for a 
train to get up the mountains than it does to go on the flats, and then the 
otherthing is you could in theory provide a lot of energy when you are going 
downhill.
Perhaps if you wanted to have a fully electric locomotive maybe it might be 
useful (at least in the beginning) to only electrify the mountain areas?   That 
might start the process.   
These all electric locomotives could shuttle back and forth as "helper" 
locomotives.    Go up the mountains.  Disconnect...and wait for the next train 
that is going down and 
provide "brakes"/regen into the grid on the way down.       Then as you said, 
you'd only need a limited amount of batteries probably to change direction and 
stuff...
