Picture if you will a wayside station in a dip between two vicious gradients, in fact it is Pinwherry, on the G&SW route to Stranraer.

Now to get out of Pinwherry, most locomen took a run down the bank, and then went hell for leather up the other side. This was a risky business, especially with loose coupled goods trains, and if a driver was not careful, a snatch could develop, with the attendent breaking of a coupling. Well, one night it happened on the last goods of the night, and half way out of the dip, half the train broke away, and rolled down the bank, through Pinwherry station, and back up the other side. Then came to a stand and back the way they had come, through the station, and back up the other bank. Stopped and ran backwards again. This process continued until the momentum was exhausted and the wagons came to a stand in Pinwherry station.

Sleeping at the station was a permanent-way inspector, whose laconic comment was that this was the busiest country station he'd ever stayed at, with a goods train every ten minutes for half the night.
