There are some point numbers and sensors used to signal between Traincontroller and the DTM30 panels. These aren't associated with proper block detectors or points.
| Point 901 | DTM30 interlock for Eastleigh. Thrown if the panel has been granted manual control |
| Point 911 | DTM30 Interlock at Portsmouth |
| Point 912 | DTM30 Interlock at Portsmouth |
| Point 913 | DTM30 Interlock at Portsmouth |
| Point 921 | DTM30 interlock at Clanfield |
| Sensor 161,1 | Sensor ON when the Eastleigh depot flap is in its correct down position |
| Sensor 160,1 | Sensor ON when the Eastleigh interlock requests local control |
| Sensor 160,5 | ON to request that the oil train from Eastleigh schedule is started |
| Sensor 160,6 | ON to allow use of road 1 in Eastleigh depot |
| Sensor 160,8 |
ON to allow use of road 2 in Eastleigh depot. |

The sensors all operate Flagmen: first assign a contact indicator, then create a flagman triggered by that contact indicator. The "phantom" points are operated by standalone turnouts on a switchboard not associated with the "real" railway.
