And fortunately for those of us steam (and RR history) enthusiasts, the UP bean counters have apparently been told to count other beans -- UP has invested some real money in their heritage program. It would be interesting to know what the resurrection of 4014 has cost them -- its not likely that it will pay off as a revenue-building exercise. OTOH, its a lotta good will and publicity - as the crowds it has drawn suggests.
Just the idea of plucking one of the very largest stream locomotives out of a park (where it sat for 50+ years) with the intent of getting it back on the rails under live steam (not to mention switching fuels) and then driving it around on (mostly) mainline rails shows a real commitment (and lack of temerity) on UP's part. And kudos to them - not something that the other class 1 RRs seem to be doing.
