That I do not know, Jeff. In my mind, a "mini" work train would be powered by the Brookville and consist of a work flat loaded with ties, spikes, and tools, Ichabod, and a second work flat to transport the tie exchanger. The ties would be distributed in the work area, the machine unloaded, and the work would begin. To clear up for a "real" train, it would be necessary to either lift the tie exchanger off the track into the clear or back onto the work flat so the whole works could proceed to the nearest siding. Once the crew gets the hang of the tie exchanger and learns its daily capabilities, presumably a work train could distribute the ties in advance, and only the Brookville locomotive, Ichabod and the work flat to transport the machine and tools would be necessary. All these details remain to be worked out.
Note: As built, this type of machine was equipped with two retractable rubber tires on one side and a pair of handles on the other, such that a couple of strong guys could "wheelbarrow" it off the track when necessary. Our machine is missing this feature, although the lifting handles remain. Whether someone wants to engineer putting set-off wheels back on is not my call.
