I am sure there are other people who have better information than I do, but I'll mention a couple of things. As I recall, one of the cylinders is damaged. Depending upon the repair technique used, there might be some additional expense. Also, I do not know what the current state of the bearing blocks is. There might be some additional casting work necessary there. When it comes to reassembly, there is certainly a lot of work to be done. Some of this work involves installing the vacuum braking system, which has a molded rubber diaphragm that probably needs replacement, and installing the various elements of the electrical system and steam distribution system, some of which might require replacement or rebuilding. As each part of the locomotive is reinstalled, there is a good chance that repair or replacement will be required. Thus, while the major expense, the boiler, has been taken care of, I expect that there will be a number, a large number, of small additional expenses discovered as the reassembly process goes along.
