Surveying Rail Vehicles

GLM Lasermeßtechnik is a service provider for scheduled and unscheduled rail vehicle surveying. The surveys are carried out in accordance with DIN 27202-10. GLM measures your category A rail vehicles (e.g., locomotives, freight cars, and related vehicles) and category C (e.g. passenger cars and light railroad cars with bogie). GLM surveys require the following preparations:

• The axles must be removed from the railroad cars so that the pivot or the spring bracket holes are exposed.
• The measuring points must be cleaned.
• Category A vehicles must be (approximately) in a leveled reference position.
• Category C vehicles must be in a stress-free reference position.

Optical surveying instruments (measuring station) and specially developed software are used to determine the dimension (DIN ISO 286-1, diff actual size to nominal size). In case of series measurements, GLM can program electronic test sheets for the customer. The expected measurement accuracy is in the range of 1/10 mm.
