The Lionel Northern Pacific GP-9 No. 2349 would be produced on a BLACK body that was painted GOLD with RED rubber-stamped striping and heat-stamped lettering in 1959 and 1960. This engine was equipped with Magnetraction, a horn that was operated by a D Cell battery, a three position directional unit whose control lever was adjustable from underneath the chassis, and a single vertical worm drive motor that powers two axles. The body was lighted at both ends that have operating disc couplers. Reproduction shells have silk-screened lettering. There are no variations.

All of the Lionel GP-7 units will operate equally well on O and O27 gauge track.
