The FRA EMUs provide flexibility - they can run into Union Station, and the outer fringes of future routes could be shared with the freight lines if they don't need half hourly peak service.No they do not. The FRA's allowances for alternate compliance would have readily allowed UIC EMUs to operate into Union Station right alongside Amtrak and even freight trains. The single track portions almost all have double track provisions. There is one bridge which does not, but they could just build another one right next to it if they really wanted to; there is space on the ground for more pylons. The single track portion of the new Westminster line even has the second track in place, just no wires or platform yet. Provisions which effectively cannot be built for the next 30 or so years. That's kind of the downside to a DBOM. Unless the state coughs up a very large amount of money, they're stuck with the system as built. That's why it was so important to get it right from the beginning and so distressing to see them cut corners from the rolling stock for the sake of holding on to obsolete FRA designs. also like that they have locked themselves into increased frequency to address capacity issues for the new B and G lines - the platforms are only 2 1/2 cars long. Or they'll be stuck with crowded, slow trains and an extremely expensive rebuild to accommodate longer trains. Look to Vancouver and Rotem's cheaping out on the Canada Line platforms. |
