NZR B class (1899)
 The B class of 1899 was a class of steam locomotives that operated on New Zealand's national rail network. An earlier B class of Double Fairlies had entered service in 1874 but as they had departed from the ownership of the New Zealand Railways (NZR) by the end of 1896 the B classification was free to be re-used. Despite early difficulties they were amongst NZRs' most influential designs.
