In real life I think the location would be worked by a loco and a horse. I have both but the horse lacks animation. So I want to use a mixture of rope shunting, a local 'pilot' loco, and simple push-pull operations. The pilot will be '
Lady Marion'. I have got as far as writing up some cards for wagons and their loads, buying a set of playing cards and even compiling a detailed list of train formations.
I imagine, each freight operation will begin by removing whatever stock is in the sidings before bringing in one or two new wagons and placing them in the goods yard or beside the platform. These will be interspersed by passenger services, which can be a push-pull (one Stroudley brake third) or a slightly more conventional train using a saloon and a brake van. The push-pull having the advantage it can arrive and depart while there are other wagons and a loco on the layout.
The track gets clogged up very easily if there is a goods brake van involved so freight trains might have a red flag on the last wagon instead. I am told the Ffestiniog Railway did this. So "my railway my rules" but trying to find a precedent for individual practices.
