Not sure why you're focusing on North America for battery stuff. Battery design and electric motor design does not change with the continent; in fact they're not even railway specific technologies.Where has the battery module been used in revenue service? I highly doubt they would use something that has less than 5 years of real time service let along service in NA
That said, bits and pieces of the product line I mentioned is deployed to various scales in 100 cities, including Toronto. The minimal use is for creeping into a station during a power outage but it can be scaled up (or down) through the use of more modules for regular service.
Absolutely no passenger train car in North America is suitable for what Metrolinx has tendered. Whatever we receive will be a custom design.
