1943  . . . as the roaders could not reach further than a mile or so, rails were laid on the skid road and a weird type of locomotive developed that would climb hills, rails, or practically anything. This mechanical abortion dragged the logs for miles between the rails, which were merely laid on a skid road; this locie, due to its climbing ability, was called a Climax.
1956  Curley also drove a lokey at Daddy Lamb's homeguard camp at Menzies Bay--around 1921. . . .
1964  The trammer now, however--and he has other titles--is the driver of a battery or trolley-powered engine known as an electric mule, a motor or (more frequently) a "loci."
