If the alternative is to sink millions, if not at least a billion dollars into extending the platforms over some vague timeline then simply ensuring all rolling stock on the Canarsie Line is equipped with a CBTC system costs almost nothing, can be done on a far shorter timetable, and is far easier to implement.You have neglected to factor in the TA's specification for car borne equipment that is proprietary, already obsolete and no longer manufactured. The cost for equipping a train with this obsolete equipment is approximately $4 million per train, in addition to the cost of the train. The lead time to get this equipment on a special order is 2 to 4 years. Even with the additional trains, the 14th St Line will not be able operate at service level capacity of 24 tph because of insufficient CBTC equipped trains. They will need another order to get sufficient number of CBTC trains to operate at the line's service level capacity. The alternatives were: keep the existing 80 year old signal system and add any avaialable 60 foot rolling stock or replace the 80 year old signal system with a modern solid state traditional block system at about half the cost of the 14th Street CBTC implementation in about half the time. |
