A number of steamer that require large radius curves actually only need them because of either the tender or the coupling between the tender and the cars behind the locomotive. I know the coupler on the TMCC Three-truck Shay is the limiting factor for that locomotive, the actual locomotive has no issue making O31 curves, however that all changes when there's a car coupled to it. There's actually a K-Line extension piece for the couplers that allow it to actually bring it's cars on O31 curves.
