Attached is a photo taken from the cab of a standard gauge locomotive of a crossing of a two-foot gauge line in Queensland, Australia. Note the manual signal to the right, which the narrow-gauge train must set before crossing the standard gauge line. To the left, another narrow-gauge track parallels the standard gauge. Queensland has an extensive network of two-foot gauge lines serving large sugar plantations, some of which feature double track with automatic block signals, multiple-unit locomotives and lengthy trains with radio-controlled "brake wagons." A brake wagon is a ballasted flatcar with an air-compressor to help control the train composed of unbraked can wagons.
