And then asterisked the northside projections up saying that the cab signal-less version of ACSES used northside needs additional testing, and the cab signal-less ACSES + freight I-ETMS used for Pan Am needs additional testing and integration.
Southside alone is going to need the full extension and probably the +2 years to 2020 because of the cab signal installations required on Needham, Franklin, and the inner Worcester as prerequisites for installing ACSES with the southside's back-office. If you use Metro North's Port Jervis Line re-signaling as a measuring stick, they might be lucky to get the first shovel in the ground on one of those lines by 2018.
