Based on cars built by ACF in the late 1960s and 70s, these ready-to-run models feature a prototypically detailed body with realistic ladders, brake wheel and see-through end crossover walkway, detailed diecast metal underframe, separate brake system and air reservoir, as well as AccuMate couplers. In addition, the cars feature 70-ton roller-bearing trucks, and accurate painting and printing to match the prototype.
