Posted by J trainloco on Sat Mar 24 18:12:12 2012, in response to Re: Staten Island North shore cars (Re: And the R-179 contract goes to....), posted by Jackson Park B Train on Sat Mar 24 16:15:50 2012. The LR/HR issue is bogus. CTA has third rail on the ground w/grade crossings,Cleveland has catenary LR/HR mixed equipment w/platforms to match.You can have grade crossings with 3rd rail, but not street running. Also, you can mix low and high platform equipment, but they can't stop at the same platform. To me, that's the only tangible separation of modality. Rapid transit can serve low platforms (typically as light rail) or high platforms (as "metro", or heavy rail), but not both (typically because such solutions would either sacrifice time to vehicle capacity). Commuter rail can operate vehicles that accommodate both. |
