Both the Bayonne and Verrazano bridges have approaches with 4% grades. These are considerably less than those specified by light rail manufacturers. The minimum seems to be the Bombardier Flexity Classic, which has about a 5% capability, while the Skoda Astra is capable of climbing a 9 or 10 percent grade. Most LRVs seem to fall into the range of being able to tackle 7 to 8 percent grades, and that includes most LRVs similar to the Kinki-Sharyo (who is quite reticent on such details) LRVs that NJT operates. Presumably the MTA would go for some similar vehicle, whether it be a Kinki-Sharyo, a Bombardier Flexity Swift (like Minneapolis), a Siemens Avanto (like Houston and San Diego), or some variant of the Regio-Citadis from Alstom, which has yet to be imported to the states. In any event any of these vehicles would be quite capable of climbing both the bridges without too much |
