Which tracks have the third rail at Jamaica Storage Yard?

• A. Tracks 2 and 3 only
• B. Tracks 3 and 4 only
• C. Tracks 1 and 4 only
• D. All tracks have third rail

Answer: (C)

Third rail supplies power to trains that run on electric traction, and in a storage yard that power is often limited to only the tracks that actually need to move electric units in and out of service. The Jamaica Storage Yard diagram shows the third rail on tracks 1 and 4, meaning those two tracks are electrified. Tracks 2 and 3 do not have the third rail, so they’re non-electrified and typically used for non-electric storage or diesel operations. Electrifying every track would raise safety and maintenance costs without added benefit in a yard setting. So, the tracks with the third rail are tracks 1 and 4.
