Classification
Incoming trains can be separated into groups of cars according to destination, then assembled into outbound blocks and trains.
Flat switching
A switching locomotive pushes or pulls cars through turnouts into classification tracks. Crews coordinate movements carefully in busy yard territory.
Hump yards
In a hump yard, cars roll by gravity from a raised hump toward classification tracks while retarders and control systems manage their speed.
Local freight
Local trains leave yards to serve industries, setting out and picking up cars before returning to a terminal.
Intermodal terminals
Modern intermodal terminals transfer containers and trailers between trains and trucks using specialized lifting equipment.
