In 2011, Glassfiber Products NorRail delivered and installed railings in the train workshop hall of Mantena AS in Sundland.

Approximately 300 m of fixed and sections of demountable railing were delivered. The railing should be easily removable during maintenance and repair of new Flirt trains. The first Flirt train was put into service on 1 May 2012. Due to the danger of high voltage, electrically insulating railings have been chosen. profiles which also has high strength and low weight.

Mantena AS carries out repairs, modifications and maintenance of all types of electrical and mechanical components in various rail vehicles. Modern facilities have facilities and equipment for professional maintenance. See their company presentation at the bottom of the page.
