See attached image and save - trains are passing signal 18 when a route is set onto the DPL without permission or getting a permissive aspect. That is a TCF by signal 90. This was a save from the previous version of the loader, which has since been updated.

I can see in the save game that 4M95 is moving at 20mph. Have you got a 0750 Snapshot that we can try and replicate the incident with?

I've run that save game through and repeated the with both the train in question and the train before. When I tried to signal a train off the loop into P3 at oxford, it came up with ' Call-on route set from the signal in rear' which makes me wonder if OX18 has a hidden Call on signal attached to it. If it does, then that would explain why trains are PSAD at this signal.

I was led to believe that it was OX126 on the loop causing that. If a route was set from 18, while it was at red, a train would decelerate to 0mph at OX18 and then accelerate away as it PSAD. However if a route wasn't set then it would stop in the normal way.

Missing position light - the driver can see it but the signaller can't! Will be fixed per JamesN's ticket number.

The lack of overlap at the exit signal also points towards a calling-on route set.
