Blonde Girl Strips Her Red Underwear On The Railway

Rails are produced in fixed lengths and need to be joined end-to-end to make a continuous surface on which trains may run. The traditional method of joining the rails is to bolt them together using metal fishplates, producing jointed track. For more modern usage, particularly where higher speeds are required, the lengths of rail may be welded together to form continuous welded rail (CWR).
Jointed track
Jointed track is made using lengths of rail, usually around 20 m (66 ft) long (in the UK) and 39 or 78 feet (11.9 or 23.8 m) long (in North America), bolted together using perforated steel plates known as fishplates (UK) or joint bars (North America).
