Light passenger rail is ideal for batteries. With lightweight trains and low rolling resistance, coupled with regenerative braking, it should be pretty easy on the batteries. The only issue would be the batteries catching fire underground...might be better for surface transport.

Or, you could use these magical things called overhead wires or the less-obtrusive third rails to supply energy to the train along the entirety of the route. And not even need batteries.

The UK has a Victorian rail infrastructure that operates extremely intensively in a tightly constrained landscape, full of buried utilities, low overhead bridges made of stone that would need to be completely rebuilt, and lacking space at the side of the routes for transformers etc. Electrification costs a fortune, £8m per route mile. Third rail is dangerous and poorly suited to the unelectrified remaining UK routes, which are mainly intercity / freight and relatively lengthy, and it needs 750V DC, which needs way more current than 25kV AC.
