5. the IRON PLATE CONNECTORAn iron plate with a length of about 50-60 cm, which served to connect the two segments of the rail rods/pieces on the plate there is a 4 or 6 holes for extra couplers/bolt (Bolt) connectivity, as well as his nuts (Nut). Stem tracks usually only have a length of about 20-25 meters per potongnya, so need to be iron plate connector component connectivity, along with bautnya. On each connection rail, there are fissures thermal expansion (Expansion for Space), so the series will sound is heard through TRAIN "jeg-jeg ... the jeg-jeg" from the sound of the TRAIN wheels pass the expansion gap.Connecting the Rails using the above components known as Traditional Connection Methods (Conventional Jointed Rails). While adults have been known to rail connecting method with a Thermite Weld, known as Continuous Welded Rails (CWR). With the method of CWR, each 2 to 4 pieces of trunk rail can be welded into one long rail without expansion gap, given that each of the CWR has a length of about 40-100 m.CWR is usually applied to the line with a high rate of speed (KA), because the surface of the Rails became flatter and smoother so that the series can pass by TRAIN more comfortable.
