The WalthersMainline EMD SD70M in Union Pacific colors, road number 3929, ready for HO scale mainline duty. Introduced in 1992 and built through 2004, the modified SD70M pairs the SD70 platform with a wide nose and North American Safety Cab. This model is based on the Phase I version.
This one arrives with ESU sound and DCC already installed, so it runs on either a DCC or a conventional DC layout with prime mover, horns and bells working from the first lap.
Underneath it is the same drive Walthers puts in its Proto locomotives: a 5-pole skew-wound motor, dual brass flywheels, all-wheel drive and pickup, and a die-cast chassis that gives it the weight to pull a real train.
