Speedkiller is a fan-fiction Thomas & Friends Series 5 episode that first aired in 1998.
Rusty is given the tedious job of spraying weedkiller on the rails. Meanwhile, Rheneas has to fetch another coach after a huge influx of visitors, making him late. He has to slow down at a steep hill for some hedgecutters too, spoiling his chances of a good run at it. Because of the weedkiller, Rheneas eventually grinds to a halt and slips down the hill. His crew put sand on the rails and Rheneas makes his way up. Though the passengers have little time to enjoy the scenery at the lake, they are pleased with Rheneas' brave efforts.
