A comment on The price of lithium-ion batteries has declined by 97% in the last three decades. Parent comment
Batteries could get a train up to cruising speed requiring a smaller train engine and less fuel.
Batteries could save on line expansion, instead of installing a 3rd rail for the whole line, they could go a 3rd rail every 50 miles for 10 miles.
I agree a 3rd rail would be cheaper in the long run. Batteries could help bridge the gap.
