For most infrastructure managers, the essential and perpetual task of measuring tunnels and other Railway Infrastructure clearance profiles requires a major commitment of both human and financial resources not to mention the rising and pressing requirements regarding safety and tunnel accessibility.
Data are often collected by manually operated measuring devices (MODs) at very low speed. When the MODs are in use they occupy track capacity which could otherwise be used by revenue-earning trains. The MERMEC Group's Tunnel and Clearance Profile product family offers modular solutions for automatic surveying and real time assessment of such a critical parts of railway infrastructure.
