The Cumberland Southern Railway's operating sessions are conducted using a variant of the "Conductor's Wheel Report" method. This method is described in detail in an article by Jim Hediger published in the May 1984 Model Railroader.
There are no waybills, car cards, or computer generated switch lists. The only form used to govern car and train movement during the operating session is the "Conductors Wheel Report". On a prototype railroad, the wheel report tells what's in the whole train, while waybills cover the handling of each car. Our wheel report lists car types across the top and the stations and individual industries (car spots) down the side. The wheel report specifies which car type gets set out or picked up at each particular industry in each station, but does not go down to a level of dealing with a particular car by its reporting marks. The value at the intersection of each row and column specifies what type and how many of each type of car is to be in the train for handling at each station, and car spot.
Each train's wheel report specifies the routing of the train from station to station and the total number of each type of car to be included in each train. When the train is assembled, it should be blocked in order of station sequence. That is, cars for the first station directly behind the engine, cars for the second station behind these, and so forth. The actual movement of the train from station to station is noted by the sequence number entered in the station sequence (stn seq) columns on the left hand side of the form.
Upon arrival at each station, the operator must switch the cars in his train spotting them at the specified industries and must also retrieve a like number of cars from each car spot.
An example of a CONDUCTOR'S WHEEL REPORT form follows.
