Ideally for the comfort of the Steam Crew Coal should be stored at a suitable height for being shovelled into the Loco. Some Sheds use Small Conveyors from a ground level site, others use a digger. This is my Coal Facility at Alexisbad. Made up from left over bits of Pola or Piko Tunnel Mouth Brickwork and the Top from Newquida Wagon left overs. An all Stone or Wood Construction Facility would work just as well.
At the real Station in the old days an Open Wagon with Coal was placed in a dead Road between the Running Lines and the Loco sat on the Running Line with the Coal shovelled across. These days they appear to manage a half day on the Selktalbahn, coaling up again in Gernode half way through the Running day.
My Diesel fuelling facility at Gernrode is a Tank that I picked up at a Show (ok I know it should be Diesel but it is not normally seen from this angle). The Pump was found somewhere or other many years ago at a Shop. One of those things that when seen was pounced on, May have even been a Pound Shop thing.
