Remarks:    This type of locomotive was an attempt to produce a passenger version of the versatile little 'F'. All principle dimensions were identical to those of the 'F', but it lacked in adhesion.
In 1893-94, three of the 'L' class 2-4-0 T locomotives had been rebuilt at the Newmarket workshops with a larger boiler and enlarged cylinders to a 4-4-0 side tank arrangement. This new design was classified 'La' but again the limited coal bunker became a liability. The answer was to provide a larger coal bunker and a trailing pony truck giving them a 4-4-2 T wheel arrangement, and a further four 'L' class were converted. Three were not rebuilt but sold to the PWD in 1901-1903. Three new 4-4-2 T locomotives were built in 1902-1903 and when the conversion program had been completed in 1903, the classification, for all ten locomotives, was changed back to 'L'.
5 x La class built Nasmyth Wilson in 1887 for NZ Midland Railway Co. were taken over by NZR in 1900.[45" drivers, 140 psi, 9.8 grate, 506 heating surface, 25.0 tons, 19.2 tons adhesive.6,450lbs TE.
