rail dowel is used to secure both ends of the track to the joint. A rail dowel is a bolt inserted into a hole in a railway tie with a sharp nut embedded into the lower surface of the tie. The size of the rail dowel varies with the requirements of the rail profile. The appropriate diameter and length of rail dowel can be determined according to railway standards.
