I recently got left and right Lionel O27 switches (with remote) for my layout (#5121, 5122). I also recently purchased an MTH Rail King Santa Fe SD-90 diesel engine which is quite wide. As the engine passes by the switch, it gets derailed because it bumps into the housing for the switch motor. A lot of my freight cars are also much too wide to pass by freely. I'm hoping that there are switches out there that will provide enough room for wider engines and freight cars to pass without getting derailed. I see Lionel has O42 switches (5167, 5168) and O72 switches (5165, 5166). Any ideas if these wider radius switches will work? I'd hate to buy them and have to return them for having the same issue. Thanks.
