Controlled Siding

A Controlled Siding (CS) is a railway track that runs parallel to the mainline and is used for train meets, passing, or operational flexibility. Unlike an uncontrolled siding, a controlled siding is managed by train dispatchers using signals and interlocking systems to safely direct trains onto the siding when needed.

Controlled sidings help reduce delays and allow trains to pass, wait for clearance, or change directions efficiently. These sidings are common in busy rail corridors, where train movement needs to be carefully managed to avoid congestion.
