What is the primary purpose of a main track?

The primary purpose of a main track is to serve as a designated route for authorized train movements. This ensures that trains can travel safely and efficiently between stations and throughout the transit system. Main tracks are crucial for facilitating regular service, managing schedules, and minimizing risks by providing a controlled environment for operations.

In the context of train systems, main tracks are specifically designed to handle the flow of passenger and freight trains, typically allowing for the highest speeds and greatest connectivity. Unlike tracks intended for making up trains or reserved for yard operations, which are focused on assembling and storing trains rather than on through-service, the main track is the backbone of a transit system's infrastructure. This distinction is essential for ensuring efficient transportation without interruptions or delays caused by non-priority operations.
