I was told a 'toilet' story a while ago by one of the old hands. Apparently there was a steam loco driver in a yard who needed a dump, so he squatted down by the side of his tender at track level to do his business.
While he was there, his colleagues went the other side of the tender, and passed a long firebox shovel through, positioning it under the drivers bum. When the driver had finished, he stood up, and the shovel was extracted. Apparently the driver spend ages looking for where it had gone!!
