::)As a new member to the forum, I just want to say hi to everyone. In regard to the overheating of the can motor in the 027 Hudson engines, I have found that a high wattage transformer i.e. 100+ watts, is helpful. I have also discovered that some of the modern transformers, particularly the MRC types do not output a sinewave AC current, but instead output a pulsed AC current which means that the full output of the transformer is applied to the engine with each pulse. Transformers such as the MTH Z-4000 or even the MRC dual power 270 watt transformers do output a pure sinewave AC current and I have noticed that on my layout using either transformer, my 027 Hudson engine runs very well with no slow down or overheating of the can motor. I have found this to be true of other can motored equipped engines operated under the above scenario.
