In December 2016 two Alstom metro trains were presumably damaged in and crash. During the project János Sziklai provided engineering and technical consultancy services. At first we carried out an assessment of the vehicle condition, evaluating the damage, deformation caused in the car body, the underframe and the car body and bogie connection. After the preliminary visual inspection we performed various measurements, such as: crack detection in locations that were exposed to larger forces during the crash; the geometrical and dynamical metering of the underframe and car body; endoscopic survey of the vehicle driver cabin.
