Walthers Item #: 910-19570

Power your priority HO freight behind these WalthersMainline(R) General Electric 8-40BW diesels! Built especially for the Santa Fe for high-speed intermodal service in the late 1980s and early 1990s, they were the only versions of the four-axle Dash Eight built with the then-new North American Safety Cab (also known as a wide cab), creating the 8-40BW. Many joined the ranks of the BNSF Railway in 1996 and were gradually bumped into local service in the early 2000s. Some were sold to short line operators in 2010, and many remaining units on the BNSF were rebuilt for local service after 2019. Fully assembled and nicely detailed, features of these engines include:

• One time run of these roadnumbers, order now - limited quantity available!


• Prototypes in service from late 1980s to the present


• Available with ESU Sound and DCC for DCC or DC layouts
