IARNRÓD Éireann’s Sperry ultrasonic testing machine was out on March 5, seen here at North Wall having just arrived from Waterford behind ‘071’ No. 075.
The ‘Sperry Wagon’ (the penultimate vehicle) contains track recording equipment, which scans the rails to monitor the integrity of the steel. It often travels around the network in the consist of the weed-killing train, the tank wagons providing extra braking power.
