The Well-Oiled Machine

In modern electric and diesel rolling stock, the interaction between the train and the tracks often results in wheel wear, squealing and track damage. This article describes a new device that could help keep wheels lubricated, greatly reducing these problems. The new wheel flange lubrication system uses technology to deposit just the right amount of lubrication fed from a sump mount underneath the train. The system also uses global positioning system tracking and draws information from a regularly-updated database of problem areas. The lubricant is delivered as the train approaches critical bends. The system needs to be programmed for each rail route a train will be using and is best fitted to captive trains running the same regular route. A demonstration project using the system was successful and the first installation on a working network is expected soon.
