They added two two new substations to provide power to the line and the concessionaire has an agreement with the local utility, Xcel Energy, to purchase power off of the existing grid. So a lack of generating capacity shouldn't be an issue. Is it really a thing that other transit systems have their own power generating stations? Seems terribly inefficient.
The problem might be that our commuter rail network uses 25K 60hz AC current, not DC, and it sounds as if there might be some teething issues there.
