There's an elephant and a gorilla in the room when it comes to lifting track. The elephant is having enough people near the takeup location. If one has to drive a couple of hours (or more) before even starting work, it really cuts down on productivity.
The gorilla is finding an individual to do all the necessary legwork and organization that must be done ahead of time and afterward. He is the guy who has to arrange with the track owner for the sale or donation, figure out how and where to stage everything, recruit volunteers willing to work on the project, make sure the necessary tools and equipment are on hand each day, arrange for trucks to transport the rail, deal with permits, insurance, and so on. Afterward, he has to figure out where the scarp goes, how to dispose of the ties, and so on.
Finally, our budget is so constrained that we cannot presently afford to buy hy-rail trucks, Bobcats and other equipment, license them, insure them and keep them running for the occasions when a takeup opportunity might come our way.
In the end, a decision must be made by management whether it's cost-effective to expend scarce resources on a takeup in the face of all the other things that must be done. To my way of thinking, to do divert resources from Sheepscot for track material we cannot immediately use (60-pound rail and switch material) would not be responsible.
