Not to mention it takes close to 1100 amps to even get a train rolling. Batteries are not an option.
Many Subway trains have batteries that can deliver in excess of 10,000 amperes to get them past sections of track which have been momentarily been de-energized, So batteries ARE an option.
The batteries in my F250 superduty can deliver 1,700 amps for cranking and running the glowplugs on the diesel engine. Yes it's 12 volts but in many cases where very high amperage is required for an application it's easier to generate with a battery bank than a power supply.
