on the UP the SD90MAC'S have been restricted to 60mph or less and are now generally assigned to manifest service, they seem to be working o.k. the problem stems from ride issues, as they are pretty bouncy, however that has as much to do with UP's maintainance of track as anything. on good track they ride fine. the isolated cab seems to really bounce hard though on rougher track, something EMD needs to look into, because the SD90/43MAC'S have the same problem.
