Sideteks

Sideteks, also known as side tracks or sidings, are small side tracks or branches in a railroad system that allow trains to leave the main line and temporarily change direction. These short tracks usually allow trains to access marshaling yards, maintenance facilities, or sidings where other trains can pass while the main line is blocked.

Sideteks are commonly used on railroads with high traffic, such as goods or passenger lines, to avoid disrupting main line traffic when a train needs to be stopped or stored. They are typically branch off the main line at a designated point, such as a turnout or crossovers, and may be equipped with signals and interlocking systems to control traffic flow.

In addition to using sideteks for regular operations, railroads often use them for maintenance and repair. For example, a train may be diverted onto a siding for routine maintenance, such as changing locomotive wheels or performing repairs, without breaking the flow of traffic on the main line.

Sideteks may be located at various types of facilities, such as switching yards, terminals, or stations, and are connected to the main line by switches and signals that allow trains to move back onto the main track when maintenance is completed. The use of sideteks can help reduce the risk of accidents, decrease congestion on main lines, and allow for more efficient use of rail assets.

Railway operators and regulatory bodies, such as the International Union of Railways, have specific guidelines and recommendations for designing and operating sideteks to ensure safe and efficient rail operations.
