As mentioned, the points out at Neville Hill mean running up to Micklefield to access Hunslet East. The train starts off on a morning from Rylstone to Hull Dairycoates then returns to Rylstone. Once in the quarry the rear loco returns to Skipton. This is because the Rylstone branch is one train working and so something has to leave the section to allow something back in. Once the loco is stabled at Skipton the Redcar train then goes up the branch to the quarry. The Redcar loco then attaches to the train (formerly the Hull) and once loaded it leaves for Hunslet. Then the loco stabled at Skipton runs up the branch and attaches to the Redcar and when it's loaded it's on its way. After the Hunslet train has been discharged there it returns to Rylstone where it's loaded and ready for the morning Hull. The train remains top n tailed because of time constraints on a night and also ease of operation. Hope this makes sense?!
