"India is on the cusp of electrifying 100 percent of its rail lines, while China is nearing three-quarters of its network. Over 57 percent of the rail system in the European Union is electric. The US, which has historically prioritized personal cars over high-volume passenger trains, now can boast that it has two electric trains — and more on the way. "
They must not be counting light rail which is electric.
https://en.m.wikipedia.org/wiki/Light_rail_in_the_United_States
"The United States, with its 27 systems (as counted by the Light Rail Transit Association), has a much larger number of "true" light rail systems (not including streetcar systems), by far, compared to any other country in the world (the next largest are Germany with 10 and Japan with 9).[1]
According to the American Public Transportation Association, of the roughly 30 cities with light rail systems in the United States, the light rail systems in six of them (Boston, Los Angeles, Philadelphia, Portland (Oregon), San Diego, and San Francisco) achieve more than 30 million unlinked passenger transits per year.[2]"
The problem with light rail here is excessive heat makes the overhead wire expand and when that happens, it sags causing the trains to have to slow down. :(
In the winter, the problem is snow and ice blocking the lines and the switches.
You’d think with current battery tech we wouldn’t need the overhead wire anymore.
The best use of a battery on a train is a small one to handle junctions. You disconnect from the wire at the end of one set, go through the junction, and then reconnect at the other side. Saves a lot of ugly spaghetti wiring.
Otherwise, no, just use wires.
You don't even need that. Every electric train I know of has pickups on each car, and any break in the catenary or third rail is short enough that it can be bridged naturally by two cars, or sometimes even just one, if it has pickups at both ends.
Some electric trolleys aren't long enough to do that.
