First published 25th February 2024

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 Code Description
1 Attention, 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
2 Train Entering Section
2-1 Train Leaving Section
8 End Shunt. The line is no longer needed for a shunting move
3-5 Cancel a previously acknowleded offering of a train. The train will not be entering the section
5-3 Train 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 Code Description
4 Express Train
3-1 Passenger Train
2-2-1 Empty Train
5 Express Freight Train
4-1 Freight Train
3-2 Slow Freight Train
2-3 Light Locomotive (Train Engine running without any trailing coaches or wagons)
3-3-2 Request 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
