This machine has been developed to simulate the contact between an overhead electric line and the train pantograph contact strip. It is capable of 200km/hour sliding contact speeds. A rotary arrangement of segments from the overhead line is used, loaded by a stationary pantograph contact strip. It is designed for investigating the effects of speed and contact load on both the contact strip and copper wire. The machine includes a 'pocket' into which features such as neural section joints can be installed to study these components under service speeds and loads, but in the controlled environment of the laboratory.
