Signalling function control; Østfoldbanen Østre linje

As preparations for the Norwegian ERTMS Pilot line project; 5 of the stations on the line was rebuilt to allow for centralized traffic control. The scope of work included complete function control of the 5 stations; including the old NSI relay interlocking and trackside objects. Several level crossing installations were also included in the scope; both legacy relay installations and interface towards new BUES-2000 installations. All work was done by personnel certified as "Sluttkontrollør F" by Jernbaneverket.
