JACK ON TRACKS DECODER INSTALLS.

[zzrguy]

Get an inside look at the Athearn EMD Model 40 as I unbox it, install a DCC decoder, swap couplers, break it in, and test run it on the track. This tiny switcher packs huge cool-factor, and I walk you through everything from disassembly to JMRI setup. If you love HO scale, DCC installs, and Athearn locomotives, this one’s for you!
