The PRR Middle Division in HO Scale has a new main control panel, needed for the new PowerShield X and RRampmeter products discussed in previous blog posts.

The power flow for the command station and each boosters run parallel across the board, first passing through the RRampmeter and then the PowerShield X. Only one RRampmeter is currently installed, but as the photo shows, I have allotted space for one on each power bus. Alternatively, I can relocate the existing RRampmeter for troubleshooting purposes.


Needing a new power supply for one booster, I opted to replace two 15 year old Digitrax boosters.

The existing Soundtraxx Programming Track Booster was also relocated. Finally, everything was labeled -- a first for me!

The previous control panel is depicted in the photo below.
