Did some test runnig with the A-5 today, Decided to see what she could do. I ran out of track before I ran out of Power.

25 MT, Atlas, IM and Roundhouse boxcars and reefers, All with either MT Trucks/couplers orAtlas/Unimate trucks/couplers. And of course, the Atlas Caboose.
Still left to do, coal load, Decoder, Archer rivets, Cross Compound pumps, Class lights, tender light, Paint, and I might try some weathering with this one, Now that I have "The gospel of Weathering" According to Tom Mann....
I gotta find a N trak club or a big layout when I get back to the states to really test it, I suspect it will pull less than the stock GS4, because I had to remove some of the frame around the nose, Although, I did add some weight back to the smoke box, where the weight was removed. It's ballanced well, so I think I am back to about the stock weight now.
