The low height of the 63rd st tunnel really puts a monkey wrench in some alternatives. The M-8 cars (proven design, good track record)can do cat and third rail, building with over-running shoes is easy, and cat would be considerably less expensive capital cost wise (albeit with slightly higher ongoing maintenance costs) but will never do ESA, the cabinets/pans make them too tall. They cost more than a stock M-7 or M-9, but after the battery mods and charging infrastructure probably not. |
