If there’s one thing I don’t like about Digitrax’s wireless throttle is that there is no on/off switch on the device. This means whenever you are not using the throttle you have to pull out the battery to turn it off (and save your battery).
So, I decided to fix that tonight. Here’s just a photo look at the process and result.

Items used:
Mini SPST toggle shack from radio shack
1/4″ drill bit
Soldering iron & solder
26AWG wire

$65 and 23 days later my DT400 is now a DT402D wireless throttle.

Thanks Digitrax!

Tonight I finished up what you could call Phase 1. That is, all of the under-layout DCC bus wiring is installed, and the wire panel installed, wired to the busses, and powered.

The next step will be to work on getting the benchwork top installed and the center divider backdrop.
