It's not the best way to go for mainline track and not suitable for long distance high speed trains.

If it's infrequently used, a dual mode diesel-electric can fill that use case today.
Ireland is going to use a particularly unusual one for the Dublin-Belfast intercity route. It will have batteries, _and_ diesel generators, _and_ will run off overhead lines, in two voltages. The context is that parts of the line will take a while to electrify; it will initially run on overhead, battery, and diesel, then just overhead and battery as the lines are built out, and then hopefully finally just overhead.
