Overview
The 0-6-4 wheel arrangement appears to have only been used on tank engines. The earliest known example was the Moel Tryfan narrow gauge locomotive built for use on the North Wales Narrow Gauge Railways. It was a single Fairlie type built by the Vulcan Foundry near Manchester in 1875. It was followed by the R class and S class, built by the Avonside Engine Company of England for the New Zealand Railways Department between 1878 and 1881.
