This is domestic coal for rail purposes. All offices, shunters' cabins, C and W examiners, and every signal box had stoves. In the case of boxes, either a stove built into the rear wall (as was once the case at Par -note the chimney breast at the rear of the box) or a free-standing one, with oven. Every box required a regular delivery of coal and, in many cases, of water too. In Cornwall Largin, Probus, Gwinear Road, Treverrin, Pinnock Tunnel and several others, relied on regular deliveries of large cans of drinking water (usually arriving on the engine bufferbeam of a local freight) and of coal for heating and cooking. In summer primus stoves were used for cooking.
In the age of the microwave etc., this is now mostly forgotten! At Penzance, the buffers would be the only safe place to stable the wagon.
