My local short-line is basically a North-South route with a branch to the East. Trains originate at the North end interchange with CSX and serve customers along the line to the South and East terminus. The East branch cuts off at Berkshire Junction, just North of Danbury where 3-4 regular customers get cars.
The daily job called NX-11 is usually 20 or so cars led by a GP-38-2 and a GP-9. On some days they run with a 4 man crew and split the job in two at Berkshire Junction. The GP-38-2 runs as ‘Extra 3600’ and serves the customers in Danbury, while the GP-9 runs East as “Extra 1802” to serve customers in Hawleyville and beyond.
Later in the day the two jobs have a cornfield meet at Berkshire Junction where the trackage and grade allow for easy switching. [If anyone is interested in the track layout at “Shire” I’ll post a digram.] Once the train is all put together, they once again sign as NX-11 and run North.
This line does a fair amount of ‘shoving’ a cut of cars with the engine at the rear over 5+ mile distances. They post a crewman hanging on the lead car who regularly calls how far he can see clear track on the radio. They also do a lot of gravity switching and ‘kicking’ cars to overcome obstacles built into the track work.
I’ve tried kicking cars on my indoor sidings. Found out the hard way that an Aristo bumper won’t stop a boxcar with metal wheels
