Taupo Totara Timber Co
The TTT ran an extensive tramway system from Putaruru where it had its planing mills and timber yards, to the main breakdown mills at Mokai and from there out into the bush. The 50 mile long "mainline" from Putaruru to Mokai was built to a high standard and included a large wooden bridge across the Waikato river. The "spiral" section of the line featured reverse curves of 1½ chains with check rails, and gradients of 1 in 16. The Putaruru to Mokai section was operated as a common-carrier. The Putaruru to Mokai section was built in steel rail, but the lines into the bush were wooden.
Locos at this time included a Dubs 0-4-0T ex NZR old "A" class (A71). This
ran on the largely level section of line between Putaruru and Lichfield. The rest of the
line was run by a Climax "A" and a couple of Heislers.
In 1921 the government commissioned a report on the TTT line, with a view to purchasing the line and extending it to Taupo. That report includes the following information:
The government concluded that the cost of upgrading the line to NZGR standards would be too expensive. The civil engineering required to ease the grades and to increase the minimum curve to at least 5 chains was extensive.
