Rail signalling simulation software may be downloaded from www.simsig.co.uk. SimSig has been described by Alan Marshall of the North London Society of Model Engineers as "a remarkable and complex simulator that will test your skills and it demands quite a bit of patience to learn how to operate a modern signal box successfully.".

Train Dispatcher is a train simulator of centralized traffic control (CTC) systems. It was originally developed in the 1980s as a training tool for a commercial railroad and was then made available to the public. The software is currently produced by SoftRail (formerly Signal Computer Consultants) for Windows-based computers.
An example is the process of signalling a train in the up direction (from A to C) past a signal box B. The signal box in rear is A and the signal box in advance is C. [2] The block indicators at B are in the Normal position. The signalman at A "offers" the train to B by sending an "Is Line Clear?"
Even if the signalman receives advice that the previous train has left a block, they are usually required to seek permission from the next signal box to admit the next train. When a train arrives at the end of a block section, before the signalman sends the message that the train has arrived, they must be able to see the end-of-train marker on ...
The signal box provided a dry, climate-controlled space for the complex interlocking mechanics and also the signalman. The raised design of most signal boxes (which gave rise to the term "tower" in North America) also provided the signalman with a good view of the railway under his control. The first use of a signal box was by the London ...
A train is driving towards a signal that shows clear (green). The train runs over the AWS magnet (which is two magnets, first a permanent magnet and then an electromagnet). The electromagnet is energized. The AWS receiver detects a magnetic field in the sequence: South, North. The south pole comes from the permanent magnet, and the north pole ...
In double line working, at times when traffic is light it is convenient to "switch out" an intermediate signal box, allowing the signal boxes on either side to communicate directly for train control. On single lines this is more complicated because of the train tokens being identified with single line sections, but the difficulty can be ...
