Most of these locomotives are designed to run on 22′ plus curves and it is recommended that they are oprerated on such curves. All that said, however, they do run on 18′ curves. The manufacturer does not recommend it, but they can. Slightly bigger chance of derailing though, but with properly aligned tracks and joints properly smoothed out, you should be OK. You might want to consider slowing them down in curves if you have issues with derailment.
