You will never get 30 tph light rail on the street, and you won't get the volume of heavy rail even if you move the light rail underground (after which you may as well have built it as heavy rail).Plenty of trolley systems operated at more than 30tph once upon a time. I guess we're just admitting defeat now and turning our cities over to the automobile, eh? Incidentally Seattle's LRT is designed with that exact operation in mind. Their eventual plans call for thirty 4 car trains per hour operating from Northgate, with 12 tph to Tacoma and Redmond (thereby keeping it to 5 minute headways on MLK Way, and whatever street running ends up being developed in Bellevue), and 5tph to Issaquah. That's a single direction capacity of 24,000 riders per hour with their 200 passenger LRTs. If they ape Portland's unidirectional paired LRTs they could conceivably move more than 27,000 passengers per hour. The first few segments have been quite expensive, but that is going to pay off in the coming years as they will be able to expand to Tacoma, Everett, and other points for a relatively low price when compared to a heavy rail system. Even then, compared to heavy rail systems, which it really is closer to, the Sounder Central Link is a fairly cheap system. |
