TC2000G track circuit residual pressure tester is a constant pressure testing tool that simulates the pressure of single wheelset on the track and tests the residual pressure of track circuit.It can produce the equivalent of a pair of light rail car wheel pressure of pressure on the orbit, namely 24.5 KN (equivalent to 2.5 t), may involve the actual state of reaction train shunting is to meet the requirements of the railway maintenance rules an effective testing tool, can effectively detect the shunt bad track circuit, namely "pressure die" problem.
