Posted by Michael549 on Fri Aug 11 13:04:26 2017, in response to Re: Question: Why No Station at 188th Street/Hillside Avenue?, posted by Nilet on Fri Aug 11 11:29:21 2017. Beyond 179th Street there are 8 tracks in a two level arrangement with 4 tracks per level.The lower level train storage area can store 1 full-sized train on each track, and there are switches present allowing a "full-X cross-over" to and from all of the tracks. Trains that use the "local tracks" at 179th Street lead directly to and from the lower level tracks. The upper train storage area can store 2 full-sized trains on each track, and there are switches present allowing a "full-X cross-over" to and from all of the tracks. Trains that use the "express tracks" at 179th Street lead directly to and from the upper level tracks. Effectively this means that one could store 3 full-size trains on the lower level while leaving one track open to terminate and relay trains into and out of the 179th Street station by the local tracks. Peter Dougherty notes that two ten-car full-size trains using the outer upper level storage tracks will be "foul of" or basically block the inner upper level storage tracks. Effectively this means that one could store 5 full-size trains on all of the upper level tracks while leaving one track open to terminate and relay trains into and out of the 179th Street station by the express tracks. (For example - 4 trains at the back part of the storage area, plus the "front" part of one of the inner express tracks, with the other "front inner express track" open.) I suppose that up to 6 trains could be stored on the upper level - 4 trains at the back part of the storage area, plus 2 trains stored at the "front" sections of the inner express tracks. Leaving 2 "spots" open on the outer tracks to terminate and relay trains - knowing that the trains on inner sections won't be moving for a while. Possibly up to 10 trains could be stored at 179th Street over-night for the start of rush hours. If there was a full cross-over set of track switches between 169th Street and 179th Street - then the entire set of storage tracks and spaces aft of the 179th Street could be used for the over-night storage of trains.
