Train order station

From Wikipedia, the free encyclopedia

A Train order station, in timetable and train order traffic control, is a control point at which trains can be stopped and controlled through the use of train orders. A station requires the following:

A siding or other track by which trains can pass each other
A telegraph station or other communications means for an operator to receive train orders
A signal to indicate to trains whether there are train orders to be picked up
A name to identify it on the orders

A train order station need not be at a passenger or freight station, nor does such a station have to handle train orders. In isolated areas train order stations may be required where there are no towns, in order to facilitate smooth operation. In denser areas passenger stations may be spaced more closely than train order stations.

A station is staffed by an operator who receives train orders and gives them to trains as they pass. Upon receipt of an order, the operator makes copies and sets the signal to indicate to arriving trains that orders are to be picked up. Typically three indications are used:

Proceed (green light and/or vertical blade): No orders; train may proceed
Receive Orders (yellow light and/or diagonal blade): Pick up orders without stopping
Stop (red light and/or horizontal blade): Stop to receive orders or to wait for another train to pass

Operators also record the passage of trains by their station.

Stations may not always be staffed, and when they are closed the signal is set to "proceed" and the switches lined to allow trains to pass without stopping. The system timetable indicates the stations and when they are staffed.
