Aloha on a beautiful Sunday afternoon.
Trains are running again, I discovered that I had unintentionally wired all the track
power via this signal module.

Oops.
So while I only had a return loop at the top it worked, but now with the station and more trains drawing current
something had to give.
So I've routed an extra wire from the booster and it all works again, of course not the signal as this will first
have to be repaired.
So I just enjoyed watching a few trains run.
Then I got out the test car that I had recently acquired S/H.
Speed read out in scale km/h
