OL trains are slightly narrower; TRs are 3.124m wide. Not that much difference though. As far as I know OL train length is still unknown at this point.If they were using standard TTC subway gauge for the line like RL, they would most likely use the same new trains they're planning to acquire for Line 2, not the rockets. At a minimum, those should be at least as good as MTL's.
Oh, i always assumed they'd be slightly narrower, although I'm not aware by how much. This is fine to me.
How long are the proposed OL platforms vs. our other platforms?
