Bell Codes

There are several bell codes that the simulation recognises. These are:

General Codes

These codes are used to signal to the adjacent signal box that something that needs attention from that box

Bell CodeDescription
1Attention, I like to offer to a train or a shunting move. If accknowledged a train offering bell code or a shunt move should be the next bell code
2Train Entering Section
2-1Train Leaving Section
8End Shunt. The line is no longer needed for a shunting move
3-5Cancel a previously acknowleded offering of a train. The train will not be entering the section
5-3Train wrongly described. Once acknowledged the correct description bell code should be sent.

Train Offering Codes

These code describe a train to the adjacent box and offers to direct the train to the adjacent box

Bell CodeDescription
4Express Train
3-1Passenger Train
2-2-1Empty Train
5Express Freight Train
4-1Freight Train
3-2Slow Freight Train
2-3Light Locomotive (Train Engine running without any trailing coaches or wagons)
3-3-2Request to use the line for shunting moves. The other signal block will not expect a train to arrive at its box. The line is reserved until the end shunt bell code is sent
