The N class was a locomotive produced during 1985 and 1987 with the original order being 10 locomotives. When the costs were check on the "A" class rebuilds from B class locomotives it was shown that they were more expansive to do and the program was cancelled. With the spare parts from the A class rebuilds the order was extended to 25 with the second batch(15 locomotives) using all remaining parts of the B/A class rebuild program. Today i have made a fictional N class(N441) and put it in a livery it may never have served in, Victorian Railways 1950s-1980s livery.
