I have just built a Metcalf Sand house and water tower, not bad for the money and a bit of tarting up will be done later. However, I was wondering about the "Sand" house. I presume the chimney meant that the building was heated to keep the sand dry, but who was the sand delivered (in steam days, no particular region) to the house? Would it have been by rail or road, or both? How was the sand then moved to the engines and typically when, by the sack load at coaling?
Come to that, what was housed under the typical water tower. The tank sits on top so I presume there would be some sort of pumping gear underneath?
