A new air compressor is installed into Union Pacific GE AC4400CW No. 6891 inside the Backshop at UP’s Burnham Shops at Denver, Colorado, on the evening of December 17, 2015. Normally this can be done with overhead cranes inside the Diesel House, but the GE locomotives that were meant to be converted to AC6000CWs were equipped with larger radiators, making installation of internal components below the radiator more difficult. A forklift in a more open area of the shop does the job.
