In real life, in this situation, should the signaller have held 4S23 in the platform at Carlisle station? I set the route and then realised that there is the potential for a collision if 4S63 overran signal CE431 as 6M69 was negotiating the junction. Any thoughts? .....  Post has attachments.

The move is fine, if the risk was too great the overlap would extend over the points. These two trains will be at least a couple of hundred yards apart. Log in to reply |

Generally (there will always be exceptions) overlaps will be a minimum of 180 metres. In many cases they’ll be a lot longer.

In many cases the signal isn't actually at the end of the track circuit anyway, especially in long automatic sections. So you might have a train which looks like it's right up behind another one, when in reality there's heaps of overlap kept clear.
