About TS Marketplace: DD35 Demonstrator Add-On
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.
