A recent work trip involved some testing of a locomotive. The test track in use is just outside Pueblo Colorado. The testing program involves a ton of different tests, many of which are pretty boring to watch if you are not involved. We did get to do some high speed runs while I was there though. The locomotive is designed for 125mph so it has to be tested to 130mph. We got to blast around the track for a while. Wildlife would scatter as we approached – usually. The loco is a modern design so at this speed, things were really quite uneventful. The ride was smooth. The noise was pretty quiet and would have been better if we didn’t have instrumentation cables out of the windows breaking the normal seal. Soon you will be seeing these locos in service in a number of states across the US.
