I don't know what the current model is, but was able to find that this unit is formerly Chaparral Steel 240. That appears to be one of many variants of a "low emissions diesel" models prevalent in industrial switching operations today, likely rebuilt with a Tier IV compliant powerplant (and possible exhaust treatment to attain Tier IV).
