Building an HOn3 Mule, regauging an Athearn

[cnrglen]

I ran my 'mule' around to check the trackwork and electrical hookups on my newly relaid HOn3 branchline. Both the engine and the track needed just a bit of tweaking but otherwise ran okay.
I have a youtube video of the occasion:

Keep in mind that it's running a very old Athearn motor. If I had any other use for this unit I'd be re-motoring it.
I have an Athearn S-12 on the way that I'll be doing the same process to and I'll probably re-motor that one while I'm working on it.
