The NZR Q class were a pair of 2-4-4T type tank engines built by Rogers Locomotive and Machine Works in New Jersey. They were similar, in appearance, to the earlier K class of the same manufacturer and were purchased by the Rakaia & Ashburton Forks Railway Company^[1] for working their newly constructed railway to Methven from Rakaia, which later became the Methven Branch.^[2]
