A near total rendition of Union Pacific's 800 strong fleet of SD70ACes, with countless branding variations (including Union Pacific's new scheme), ACS/CCS cab signaling systems (for Sherman Hill only), experimental LNG marker lights, and SD70AH variations with differing physics to their SD70ACe counterparts. 
 
To top all of that off, a complete selection of Union Pacific's Heritage and Commemorative SD70ACe units is included.
 
Includes four Nathan K5LLA horns, an EMD Steel Bell and a Graham White E-Bell.
 
It is highly recommended that you read the manual before attempting to operate this locomotive.
