Edit Dec 13: I just realized that the video I referenced was moved down in the list, so it may not be obvious which one I meant. Luckily, MikeF90 furnished the youtube link below, so we’ll use his:
Jordan builds/ has built over a long period of time; Their 'Jordan Spreaders" to many different specifications; whch, in term, the ownng railroads have modified to their own needs, or specifications.
KCS RR has operated several different ones. There seems to be one that operates out of Pittsburg,Kansas, which it seems to be seen on a regular basis. Their(KCS RR) Jordan Spreaders have their own dedicated power; they are operated from the cab of the spreader; as the access to the diesels cab is restricted by having no windows.
Most of the Jordan Spreaders I have seen during my career do not have dedicated power ‘permanently’ assigned/coupled to the spreaders. Most get used in some form of work train with a regular train and engine crew operating the locomotive for the train. Jordan Spreaders are a utility tool in the MofW’s tool box to conquer the issues that maintenance personnel encounter.
Saw a recent post on TO with details (of course can’t find it). Here’s a new video on the YT WXChasing channel with good closeups (silent): https://www.youtube.com/watch?v=pcmD_hCnwHQ
