The track is the road of the train. The track is connected by different railway parts. The parts connecting the track are especially important.
Splint is railway accessories in railway transportation is very important, its main function is to connect two orbitals, due to the particularity of railway transport has created the separability of railway transportation, so in the rail joint must use plywood play loose connection, in order to prevent the orbit, to ensure the stability of the orbit can be continuous when there are vehicles bearing force of the locomotive track. There are a number of ways to connect a railway to a track, the traditional method is to attach the track to a steel rail of about 20 m, with a connection (also known as a seam) between the tracks. It is a steel plate about 60 cm long with four to six steel bolts at each end to keep small holes in the railway. The rails between the rails, about 6 mm wide, are called expansion joints. Road splint is an important part of rail transit, its connection is tight, to ensure the safety of the train, to ensure the safety of pedestrians.
