I always had a similar idea, but it needs to be done in baby steps. The EBT managment has shown several signs they intend to do at least Mt. Union to Saltillo *someday* (Robertsdale seems out without a $1,000,000+ repairs to the tunnels), the question is, will it be in our lifetimes?
What I would like to see first is perhaps at least brush clearing of the Mt Union yard. The MUCRR had made huge improvments there but alot of the cars are still covered. Start to stabilize the cars in the yard, as they wont last forever out there. There are even some standard gauge cars there, which would make for a neat display someday.
