"Steam was generated in a locomotive type boiler containing 32 tubes 1 3/4" dia. the heating surface totalling 50 sq. ft with a grate area of 3 sq. ft. The exhaust steam was passed through the ash pan to deposit any moisture in suspension and then through a heating coil in the smoke box. This was to render the exhaust practically invisible".
"Standard channels 6" x 2 ½” were used for the chassis framing and cross braced. Rear main springs were 'four feet long with secondary springs above them two feet long permitting a large movement but well damped. The fore-carriage mounting the front axle was in effect a rectangular frame pivoted at its centre thus providing three- point suspension. Steel wheels 3' 2" dia x 9 1/2" tread were used for the rear and 2' 911 dia. x 5 1/2" tread for the front on a wheelbase of 10' 3". "
