Number 32 from 1939, a two axle Tr (tractor) class is seen in Henderson in 1964. Originally it had a Parsons petrol (gasoline) engine, but in 1958 this was replaced with a Detroit Diesel 4-71 series engine developing 78 kW (105 hp) at 2,000 rpm, with the power train via an Allison torque converter. The remains of this particular loco, one of 16 similar ordered by NZR from Drewry before WW2, are stored in the Tokomaru Steam Museum.
As electric motors have much better torque than mechanical ones, diesel-mechanical transmission on railways world-wide has been almost completely confined to low speed, low tractive effort needs in yards or to railcars.

Unreal, particularly since unlike its counterpart in the United States, Canada Post makes a profit ($98 million in 2012)...
In an attempt to cut costs, Canada Post has announced plans to scrap all home deliveries, making Canada the first country in the G20 to be without a door-to-door service. Once the cuts are implemented, only some business addresses will get post through the letter box – not even residents of cities such as Vancouver, Toronto and Montreal will receive mail at home.
