That amount is obscene. How does it cost US$29 billion to electrify the system when Toronto is {potentially} electrifying it's 200km RER system for CDN$2 billion?

I say "potential" as Toronto is thinking {like many European cities are now doing} of scarpping the entire catenary plans all together and running the new battery trains saving huge sums and endless construction and the disruption and delays that come with it. Toronto {like Boston} can also get major snow/ice storms and the battery trains are immune from the damage and hence service disruptions caused by them due to catenary wire breakdowns.
