Abstract
The diffusion of brake-shoe system has made it necessary to study brake–wheel–rail interactions. This study aims to elucidate this topic with an innovative small-scale test rig, the ‘4-contact machine’. A test procedure is designed in which an ER7 steel wheel is coupled with a R260 steel rail and two different brake-shoe materials (cast iron and sintered material). The results show that the 4-contact machine reproduces the effects of wheel–rail–brake shoe contact and damage similar to those observed on a railway wheel at the end of its life, highlighting marked differences in behaviour between the two brake materials.
期刊介绍：
The Journal of Rail and Rapid Transit is devoted to engineering in its widest interpretation applicable to rail and rapid transit. The Journal aims to promote sharing of technical knowledge, ideas and experience between engineers and researchers working in the railway field.
