I'm considering buying a used set of DL 109/110 diesel/dummy. MTH says it will run on 0-42 curves. Can anyone show or tell me how much this unit hangs over on 0-42 curves? If not, can you tell me how it compares to 70' MTH passenger cars on any curves? Does it hang over the same amount, more, or less as a 70' passenger cars? Thanks.
