More complicated things to do: may require investigation or acquisition of new kit.
Track cleaning train schedule. or schedule sequence.
Consider splitting one or two platforms at Portsmouth to allow two shorter trains to use them. A bit like the shorter blocks in the fiddle yard. Trains would need to arrive at the 1st block, and a "move down" schedule would be needed. A lot of schedules would need to be edited! BDL169 #30 has 5 spare detection sections, including all of Zone D; so sensors are available.
A list of simple things to be done: the idea is that each might take an evening or afternoon.
Look at the front bogie of the class 159, non driven end: it doesn't seem to detect on the "stop" sensor.
Ramp speeds into Clanfield.
Run a power wire for the MQTT gateway.
Check coupling height on the GWR and BR steam carriages. Some are low; one dangerously low.
Edit the schedule sequence green fiddle to Portsmouth: for a small DMU it terminates at Orange fiddle. the train arrives into the first block, but until "move down" has run it isn't available at the start block for the second schedule. Probably, make the first schedule a "cycle" schedule to avoid the 2 split rear storage tracks.
Add an uncoupling magnet on the front road in the contained yard. A steam train returning its carriages needs to be able to uncouple nearer the entrance to this track.
Change instructions for Steam train driver at Portsmouth. When exiting the yard to the station approach, need to start onto the "downhill" section and wait for the track on the Portsmouth flaps to report unoccupied.
Add a "manual separate" button for Clanfield track 1 to the DTM30.
Test the new Clanfield goods sequence.
