What tracks can W/B trains access at Jamaica from East Layup?

• A. 1-4
• B. 6-8
• C. 10-12
• D. 5-9

Answer: (D)

Access from East Layup is determined by which turnout connections line up for a westbound movement. Only tracks that are directly connected to East Layup by those turnouts can be used without extra moves. In this layout, the westbound route from East Layup feeds into a block of tracks that are five through nine. Those tracks are connected to the westbound main, so a westbound train can enter any of them directly. Tracks outside that group either branch off to different parts of the yard, are reserved for other directions, or require additional moves, so they aren’t accessible from East Layup for westbound access. The tracks you can access are five through nine.
