Growing urbanisation results in growing transport networks composed of underground railways, trams and suburban commuter trains, which have a lot in common: low axle loads, commercial speeds of 50 to 80 km/h, tight clearance envelopes and obstacles such as power rails. As a rule, maintenance, cleaning and measurement work is carried out during off-service hours at night or even during service hours. Noise and exhaust gases are major issues – both in terms of emissions produced by work machines and those caused by the rails’ roughness in service. Apart from meeting these requirements, we offer uncomplicated transport solutions between networks.
