[2] The tramline runs through the Waitakere Ranges from Jacobsons' Depot to Seaver Camp near the dam at Upper Nihotupu Reservoir.

[1] One of the locomotives is a 3 tonne diesel-hydraulic unit, powered by a 40-horsepower Isuzu diesel engine with a maximum speed of about 14 kilometres per hour (8.7 mph).

Another incident occurred on 4 May 2002, when a child fell from a carriage of Rain Forest Express Train No 1337 while it was travelling through Tunnel 29.

The child was seriously injured when he was crushed between the 610 mm diameter water pipeline and the moving train, causing the derailment of a bogie on two carriages.

As a conclusion of a risk assessment, a stiffening aluminium rod was to be installed at the top of the vinyl doors of the carriages.
