Hi Russ,
Nice subject and idea you have brought up here. I have seen one in HO that work fairly well. Personally, I like the flat switching better. Another friend of mine had a nice little yard, about the size you described. I would use an engine that didn’t have a fly wheel. He had Kadee couplers and magnetic ramps. I would uncouple the cars over the ramps and then push them fast enough to roll a ways down the track. The non-fly-wheel engine would stop fast and allow the cars to roll into the yard tracks. It was very similar to how we used to switch in Stockton yard. I would like to try a flat switching yard on my layout.
Flat switching, as it was called, required speed. We would start by gathering up a rail, which was really going into a yard track and couple up all the cars. Then we would pull out a cut, a predetermined number of cars from the whole track. The number of cars would depend on where and how many were going where. Some cuts could be as long as 50 cars. Most were in the 20 to 30 range. The foreman would decide, by looking at his list of cars, how many to switch. Once the cut was pulled out of the rail, he would give a kick sign. The engineer would run the throttle up to run 8 and make the engine go as fast as he could. The pin puller would be at the car that was to be let go of and lift the uncoupling lever. The cut of cars would get up to 10 miles an hour or so and the foreman would stop the move. The engineer would stop the cut as fast as he could. The car would roll free down the lead to the track listed on the list. The fieldman would line the switch for the lead and have the next car lined into a different rail. This would go along until the cut had been completely switched. The pin puller would then take the engine back into the rail and get another cut of cars. This would continue until the whole rail was switched out. Some times a 70 car train would take 70 minutes to switch, while other times it could be done in an hour, depending on the number of cars let go at a time. In Stockton, we had a slight hump on the lead, but we still needed to really kick the tar out of those cars. Stockton wasn’t a huge yard, but it did have 27 or so classification tracks. With a good crew, we could switch out 300 or more cars in a shift. Often we would switch out a rail and then gather up the cars and put them on a departure track. What we were doing then was blocking cars and putting them in order of the work. The cars to be set out first went into the rail first and so on till the last cars were put in for the destination of the train. The best engine I ever pulled pins on was a GP-9. Buy the time I became an engineer, the best engine was a GP35. We had one that really move fast and would drag a cut of cars to a stop fast. Those days are long gone now. We aren’t allowed to get on or off moving equipment. Stockton is now the realm of Remote Control Locomotives.
