The track system plays a vital role in an ecological analysis of the railway. If points fail, trains will have to wait but still have to be supplied with electrical power. Siemens electromechanical point machines help reduce delays caused by failures and maintenance and ensure trouble-free operation of the track system. The S 700 saves on lubricants and fuels and prevents leakage losses and the resulting pollution of the soil.

An additional benefit for operator and environment is the point diagnostic system Sidis W. It is a computer-aided early warning and control system that enables the operating status of the system to be monitored and therefore allows the points to be maintained when their status demands it. Unnecessary starting is thus avoided.
