I got a wild idea to run all of my O gauge tinplate at once today (well almost all of it). I didn't get the O27 and a few cabooses on the track and may have missed a gondola. My AF 1681 gave it her best, but wasn't quite up to the task with the heavy MTH 2800 series cars added. So, I needed to bring in more power from the engine shed. Here she is! No. 1604, all twenty wheels of her!
Here she is coming around the bend!
To facilitate this folly, I made a coupler adapter from a broken Lionel latch coupler and an extra AF hook coupler. The AF hook fits right into the Allegheny tender knuckle coupler.
