definately not scrapped on the UP. They had been restricted to 60mph or less for a while, and were primarily assigned to the I-5 corridor in manifest service. Apparently there have been some modifications done to the trucks (I believe they have added another shock, there are now vertical motion shocks on all axles both sides). They are no longer speed restricted and seem to have found a niche with auto racks (I've had 10 or 12 in the last couple months on racks). They can also be found on intermodals, and some manifest trains. These things are beasts now that they have most of the bugs worked out. Phenominal dynamics, especially as the speed gets lower. Really dig in and pull too. Still a little bouncy. The GE's still seem to be having some problems, I get 'em now and again, but they are usually full of faults in the computer. Had one that was only putting out a little over 3000 horsepower. Also, like most GE wide bodies, they have that darn lateral motion above 50 or so.
