What Have You Done To My GP50?
UPY 2100 is a brand-new genset locomotive, designed for yard work and transfers.
In a previous life, it was MP GP50 3514, acquired in 1980 to power hot intermodals on the Chicago-Houston corridor. It was retired by the UP and converted by Motive Power Industries in April 2006. The genset is equipped with a CAT 3516C diesel engine, with Tier 2 compliance, which includes EFI fuel injection and aftercooling.
