I bought a second one because the first runs so well, pulls pretty well, and sounds good. I grew up a mile from the NY,NH,& H mainline to Boston near New Haven. The spur to the gravel quarry, The Branford Steam Railroad was a short bike ride. I spent a lot of time watching the operations there. I saw a lot of these working together, and I am a real sucker for a lash-up. These look great together and are pretty well speed matched out of the box. Cheers
