Along the entire length of the SAS, allowance was made for two third tracks - one at 72 St and one south of 42 St. These are the only places to move a problem train to and continue to allow thru service to operate. 72 St also provided for having trains use the outer tracks for thru service while terminating a train in the middle. Without this third track feature, they'd essentially be building the current L line as a Manhattan trunk - and go ask L line riders what happens when a train lays down. |
