Haven't done much with trains in 2016, but had a few hours to take a QSI Titan decoder I traded for and slipped it into an MTH SD45 chassis that once had PS2 electronics (not-DCC compatible).
I took a GoPro 1080P-60 video of the first basic test...did the Q3 software upgrade work? Did I wire the motors correctly? Did I wire the speakers right? Seems good to go.
Note...no lighting yet...waiting for the 3mm LEDs.
The decoder itself is running a stock QSIS 645 Q3 large-scale file. Horn is an un-adjusted Nathan P5. I'll adjust everything to taste after I install the lighting.
The track is a few pieces of AtlasO 36" Curves.
Not much, but enjoy.
