Yes,but things like an advanced signal system,high platforms and grade separation are an absolute must for rapid transit.Are they? I suppose by definition, Rapid transit requires grade separation, but these rigid definitions of what's rapid transit and what's commuter rail hinder possibilities in this country (a point AEM7 makes all the time). Take for example RIVERline. It's not commuter rail, yet it uses low platforms and doesn't require grade separation. And on the other end of the argument, it seems as though we're going to require ANY passenger rail system to implement some form of an 'advanced signal system' sometime soon. Establishing a minimum standard for each mode of transportation is becoming an increasingly difficult thing to do, which is why i'm not sure that you can simply set a generic standard for infrastructure costs per mode. Each example needs to be looked at on a case-by-case basis. |
