As an Aston fireman in the late 50s early 60s I think the trains you mentioned was the Lichfield day pick-up. The coal trains were picked up from Lichfield after being left by Burton men who then took a train of empties wagons back to Derby. From Aston we used to travel light engine to Lichfield we then spent a couple of hours shunting, about 12 o'clock we would start working back with a mix train to Shenstone where we again did some shunting, dropped off some wagons and pick-up some empties we then preceded to Fouroaks where we again shunted, we could be there for an hour or two, we then set off to Sutton where we shunted, dropping off wagons and picking up empties, our last stop off was Erdington, shunted, pick-up empties, we now set off for Aston Goods where we ran round the train and push it into the goods yard. That's us done, back to Aston, finished. The Diesel shunter a Aston goods would then shunt the coal wagons into Windsor St Gasworks. The engines that we used on these trains were mostly: Class 8s, 5s, and Crabs.
