Rapido HO GMD-1 w/stripes
1600-Series (6-Axle) GMD-1A
In 1988, CN began a comprehensive rebuild program of 15 of its 1000-series, six-axle GMD-1 locomotives to provide the remaining prairie branchlines with reliable, lightweight power. The rebuilds were performed by CN’s Pointe-St-Charles shops in Montreal and included: upgraded 645C power assembly; anticlimbers; ditch light brackets; straight exhaust stacks; upgraded sanding; improved traction motors; and Wabco 26L brakes. Most importantly, the units received a john in the short hood! The batteries were moved to the sides of the cab. To make switching easier, the units were oriented short-hood forward.
These locomotives were classified GMD-1A, or GR-612a. They operated primarily in the Prairies until their next rebuild between 1998 and 2000. More on those below.
Our model features operating ditch lights on the short hood end.
1400-Series (4-Axle) GMD-1B
CN followed the 1600-series rebuilds in 1988 with the 1400-series rebuilds in 1989. The main difference between the 1400s and the 1600s were the fuel tanks and trucks. With the closure or selloff of most of CN’s lightweight branchlines, there was less need for six-axle units with their reduced pulling power.
The GMD-1B received a larger, 2000 gallon fuel tank and the four-wheel Flexicoil trucks taken (in most cases) from retired GP9s.
The 1400s operate long-hood forward, and our model features operating ditch lights on the long hood end.
