Working on Power District (PD) 3 being the RG main line from Denver to the Moffat Tunnel on Module 8+7
- Track successfully installed for all of the track blocks T407-T412. All wired and trains run ok.
- NCE BD-20 track detectors installed for all 6 blocks. 3 loops of solid feeder wire used.
- After a lot of time waste due to the 9cDV polarity supply being incorrectly identified they all now correctly light on the board when the block is occupied.
- 2 blocks overnight lost power due to inadequate solder connections. Resolved and all ok now.
Previous completed work on PD3 on Module 8+7
- Control Panel constructed, plan drawn and all turnout DPDT switches and LED lights installed.
- Preference would have been for SPST momentary contact switches + Gaugemaster GM500 latching relays. However GM500s failed to work after many attempts and different relays. Gave up and reverted to DPDT switches + push buttons for power from the CDU.
- All DPDT turnout switches now installed and all working ok except P305.
- Track cleaned on Tuesday 04/04/2023 with ACT-6006. Appeared to immediately work ok – no stalling. However locos often need a big 5 nudge to initially start.
Next Action on PD3 on Module 8+7
- Install block occupancy LEDs on control panel – linked to the BD20s.
- Extend wiring to blocks before and after T407-T412 for testing.
- More through loco testing including real trains with consists.
- Repeat PD3 action on PD5 (Booster #3) UP/CBQ main line.
- Test thoroughly and then start to add scenery.
