"2-6-4 tank engine number 790 ""River Avon"" and a class N 2-6-0 goods locomotive number 810, about 1925. These two locomotives had been built for the South Eastern & Chatham Railway. Tank engines did not need a separate tender for water and coal. They could either push or pull trains, which meant that they did not have to be turned around on a turntable at the end of their journey. They were normally used on local lines, as they were rarely powerful enough to haul long trains."
