Hi, I was wondering if there are systems in place in the event of a large scale power outage or blackout, for electric trains to get their power and continue running apart from the grid?

Thanks

There is none on any system I'm aware. Battery technology is not yet up to the required energy storage and lugging around a diesel engine and fuel supply in the rare event a system outage occurs is just moving dead weight.

That said, I do know that some light rail trains do have a 'limp mode' battery backup that can carry short trains a limited distance, if only to get out the way of street traffic and offload passengers at the next stop.

Exactly. NO power they are stuck until a diesel can come rescue them. That includes most lighting and all heating/air conditioning being gone. Battery provides lighting for a number of hours. On our diesel commuter we have 16 hours of battery backup for lights in the cars
