Monitoring the Geometric Position of Transition Zones to Increase the Quality and Safety of Railway Lines

Transition zones on railway lines are localities with gradual changes in the construction layers connections between a fixed track and ballasted or wide various objects, e.g., tunnels, bridges, culverts, etc. The different type of transition causes shock wave when train passes, which can cause undesired effects stability its construction, durability, passengers’ comfort. For this reason, opera-tors pay increased attention to inspection these sections. research deals description zones, methods, results their monitoring experimental sections corridors. Innovative aspects measurements made using precise geodetic instruments as well continuous KRAB trolley. analyses show whether geometric spatial position is ensured.
