RTR ALCO C420 DIESELS
This release of the C420 is a low-nose “phase 2” model. All Phase 2 versions will feature the low/vertical mounted engine air intake located ahead of the radiator area on the long hood. Early phase 2 locomotives feature phase 1-style walkways/sills with stanchions mounted into the top walkway deck (referred to as “Phase 2a” models). Phase 2a production ran from December 1964 through September 1965.
