I feel that there is a kind of common denominator between all vintage railroad equipment running under overhead wire, regardless if the equipment operated in downtown Chicago or the middle of Norway.
I love all sorts of modeling, regardless of scale and prototype, but there is something special about 0-scale equipment with trolley poles or pantographs!
A very fine example is this scratchbuilt 4-truck articulated trolley freight locomotive. The model was built by William J. Clouser in the sixties. Clouser was a fine-scale pioneer, and the model is built to Proto:48 standards. It stands up to the best of today’s models, and it is a good reminder that even with all our high-tech tools, there is really no substitute for good craftsmanship.

Hi Havard,
Thank you for your inspiration writings and postings.
I too have been very influenced by Bill Clouser and Bob Hegge.
I have just found the below on you tube and what a treat it was to see!
