I got out the old train set recently and found out the old ho engines don't work anymore. So I bought this ho CSX engine. Very satisfied with my purchase. Being new to all the changes in model trains, I have a lot to learn. First thing is figuring out how to get my old train cars to fit my new engine since the couplers are different. I knew I'd have this issue and want to go with the new couplers not change them to the old style. I do like the weight of this engine. Haven't run it at a very high speed yet. My power box is old but still works, probably do better with a new one. Happy with the new engine and think it looks good too.
