Identifying misbehaving bogies: expert software in complete automated LynxRail

“Misbehaving” bogies are dynamically unstable bogies that can affect not only vehicle and equipment performance, but can also cause infrastructure damage and derailments. Dynamic instability of bogies is caused by a range of factors, including incorrectly aligned wheelsets. The primary manifestation of dynamically unstable bogies is hunting. This paper presents a wayside system that feeds information into an expert software system to audit misbehaving bogies. The wayside system uses machine vision technology and sensing devices Hunting and tracking bogies are identified as soon as the train has passed the system. The system gives an operator immediate warning of dynamically unstable bogies, and early warning of suspect bogies. The software is used for condition monitoring, and it also identifies dangerously unstable bogies. As a result, operators are able to minimize failure risks, and vehicle and infrastructure damage. The system was tested by TTCI in Pueblo, USA.
