Drive the DD35 Demonstrator in this simulation add-on, paired with the Union Pacific DD35 Add-On. It recreates the GP35 and DD35 locomotives from their 1963 demonstrations across railroads, where only Union Pacific and Southern Pacific adopted them. The DD35 serves as a cabless booster unit, combining two GP35 prime movers and electrical setups on one frame with a shared cowling and 4-axle Flexicoil trucks-each mover drives four axles directly.
Detailed lighting brings authenticity, including number board lights, class lights, step lights, cab and instrument illumination, plus animated doors, windows, and cab mirrors. Train simulation fans who value precise historical locomotive operation will appreciate these focused details.
The DD35 Demonstrator pack, which requires the Union Pacific DD35 Add-On to use, enables you to drive the Gp35 and DD35 as they appeared in 1963 when being demonstrated on various railroads but only Union Pacific and Southern Pacific took on the units.
The DD35 was a cabless booster (B unit) locomotive that consisted of two GP35 prime movers and electrical systems, mounted on a common frame and covered with a single cowling, riding on a pair of 4-axle Flexicoil trucks. As such, each prime mover powered a single set of four axles instead of two sets of two axles, as in the GP35.
