Rapido Trains 40037 HO Scale EMD GP40 Diesel Western Pacific "Zephyr" WP 3511

Rapido is proud to announce the EMD GP40 locomotive! The GP40 series was considered the gold standard of four-axle locomotives, with over 1,000 examples built for 30 different railroads in North America. EMD began production in late 1965 with an order for the New York Central. The final locomotive in the series would roll off of the line in 1971 for the Chesapeake & Ohio, number 3794. In between that time period, the Penn Central would amass the largest fleet with the Baltimore & Ohio coming in at a close second. After 1971, production would continue on with the successor: the GP40-2.

This first run will bring you many never-produced-in-plastic variations, such as: nose and Gyra/Mars lights, stepwell variations, Canadian versions and slugs. The Missouri-Kansas-Texas (MKT) Railroad converted a heavily-damaged GP40 into a unique one-of-a-kind road slug, number 501. Rapido will be producing 501 in both MKT and Union Pacific - complete with a working motor.
