Transpennine network trial confirms battery tech can reduce fuels costs by half and allow intercity trains to travel through stations in zero emission mode
Batterie have planety of drawbacks compared to overhead wires.
Weight - Batteries way a LOT, meaning that locomotives need to be stronger, meaning they will be heavier, meaning that need stronger bridges and sturdier tracks.
Lifetime - Batteries are consumed as they are used and recharged, they are also not as easy/cheap to replace as pantographs.
Range - Batteries has limited range, normal electric trains have unlimited range.
Charge time - Batteries need charging, normal electric trains does not.
Normal electric trains are technically the ideal transportation, you have unlimited range and don’t need to carry the fuel.
Don’t forget acceleration, one of the main reasons passenger trains care about weight is that you can get up to and down from line speed quicker, thusly saving trip time and allowing for more frequency/capacity from the same number of trains and drivers.
The extra weight from the batteries means you don’t get said benefits from going to battery electric as compared to overhead line.
