The Union Pacific EMD SD60M 2-pane window variation has been customer painted by another party in the lightning bolt scheme and numbered 2501. This is a June 1992 production from Ajin Precision of Korea and imported by Overland Models, Inc. The model has no lights and MV lenses are installed. A customer installed ESU Loksound V3.5 is installed. The model runs rough likely due to its 28 years age. The model is in really nice condition and appears to only be lightly used.
