Walthers Mainline 910-19711 HO Scale EMD SD60M Diesel Union Pacific UP 2447 DCC & Sound

Introduced in 1984, the SD60 used the standard EMD cab through 1989 when regulations mandated wider "safety cabs." These later units, designated SD60M (Modified), used two different cab styles over the years; a three-piece windshield was standard through 1991 when an improved design was introduced with a two-piece windshield, which was used through the end of production in 1995.
