Walthers Mainline 910-21029 | EMD SD70 - ESU Sound and DCC - Norfolk Southern #2513 | HO Scale

The WalthersMainline EMD SD70 in Norfolk Southern colors, road number 2513, ready for HO scale mainline duty. Introduced in 1992 and built through 1999, this version of the SD70 carries the spartan cab shared with earlier EMD diesels, making it an easy stand-in for a wide range of 1990s freight assignments.

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.
