American Motive Power Inc. had a Trackmobile and their home constructed shop switcher, constructed from a variety of locomotive parts that were on hand, completing what they jokingly call a SW10.5 in 2008. There is no frame number on the unit however shop sources believe a hoax/frame would use from an NYSW unit… It is used intra-facility for shop switching and to service several customers within the confines of the industrial park that AMP resides.
