I came across this add in a copy of Railroad Magazine--1953--...older than me....ha ha

I have been out of model railroading for a long time [ten years], but playing with SCARM and some track plan books has kind of given me the itch again, that and visiting the local rr club's open house night.

And I find that the TP56 exists and it really tickles my love for esoteric motive power. That and it seems a literal halfway point between a road switcher and a shunter/shifter, supposedly weighing 80-100 tons.

The past week offered opportunity to get back into the basement after almost 7 months away from the railroad and continue to make progress in any way possible. After a successful winter work session, the project list was still long with a few major projects remaining before more intricate and detailed work can begin. Some time was spent on each major goal, and the coming week will provide more opportunity for work.

Been thinking about this for awhile and took the plunge last week.

I needed a switch / control mechanism that I could mount in foam and be able to remove easily if needed.  I didn't want something I would have to destroy scenery to work on it.

Here is a link to a youtube video that shows the operation of the first one I did.  Have done 3 more and so far they all work fine.
