Ever wondered how subway tracks are made? Linden Yards in Brooklyn holds the secret. This isn’t just any storage yard. It’s the only shop in the entire transit system dedicated to fixing and replacing subway track and switch gear.
Linden Yards opened in 1977. It’s unique. It lacks a third rail. It even connects the subway to the main US rail network. Imagine the logistical marvel. Materials and equipment arrive by rail from across the country. They’re stored here ready for use.
The yard is massive. It serves the nearby Linden Shop where MTA workers build track panels. These are pre-assembled sections of track. They replace old rails and ties on aboveground subway lines. Underground tracks are built on-site. Space is tight in the tunnels.
Linden Yards has a fascinating connection to the national rail network. This makes it ideal for storing materials. It’s one of only two connections between the subway and the national network.
They use continuous welded rail where possible. This speeds up replacements. Long lengths of rail are welded together. Then they are transported to their final location. Specialized rail cars carry up to eight of these long welded sections.
They even use thermite welding. It’s an amazing process to watch. The workers also rehabilitate frogs. These are rail switches. They build complete track segments. For curved sections they precisely angle the ties. This ensures trains curve safely. They also construct complex rail junctions and repair the third rail. The third rail isn’t welded. Instead thick copper wire welds each section.
So next time you ride the subway think about Linden Yards. It’s the hidden heart of the system. It keeps the trains running. It’s a place where innovation and repair meet. Linden Yards ensures the smooth flow of the city’s lifeblood.
