The NZR EO class of 1923 were electric locomotives used on the steep Otira to Arthurs Pass section of the Midland Line in New Zealand. They were primarily needed for pulling trains through the 1 in 33 grade 8.5 km (5.3 mi) Otira Tunnel which was too long and steep to allow steam locomotives to be used.
