The Perlman era NYC operations management training program was of 18-months duration. Time was divided about equally between the transportation, M//W, and M/E departments There was some variation in departmental time and scheduling based on the experience of the individual trainee and the time of year.
For M/E, time was spent at the two heavy repair shops at Collinwood and Beech Grove as well as at one of the major engine terminals, including being assigned to accompany one of the traveling "diesel weasels" (inspectors) as they rode both freight and passenger trains.
For M/W, time was spent with mechanized track gangs, welding gangs, C&S people, B&B people, and with a Track Spvr in the assigned territory.
For Transportation / Operations, assignment was to the Terminal Supt. of a major hump yard, Trainmaster at a flat-switching facility, and Road Trainmaster of the assigned division. Short familiarizations stints to the system offices for power assignments and car utilization were included, and the initial safety training was given at Detroit under the tutlegae of a super fellow named (IIRC) Jimmy Harrison. Operational rules instruction was given by the district to which the trainee was assigned.
An additional benefit of the program was that as the trainee progressed, he might be assigned to a system or district project dealing with locomotive or car utilization, scheduling, or other operational problems.
Upon completion of the assigned program, the trainee would be offered a position in one of the departments. for Transportation / Operations, this was as an Asst. TM or Transportation Inspector.
