This is Comeng motor coach 322M at Belgrave on Sunday 6th February 1999 during the proving trials of a prototype traction control system which I had been heavily involved with over the previous year. Belgrave is the summit of the electrified network in Melbourne and is approached over a long steep gradient, so is a favourite place for test trains to operate to. This route, and this train, was privatised as part of the Hillside Trains franchise (later Connex).
