Signal box opened to control an Up and Down Main style crossing loop on the completion of the
Uniform Gauge line from Kyogle to Merivale St (South Brisbane). The loop was converted to a fully
interlocked Main and Loop style installation in 1944. At this time an extension 4 ft long was added
to the Sydney end of the building to accommodate the larger interlocking machine.
The signal box was closed with a signal rationalisation project between Casino and Glenapp as part
of a plan to install Train Orders. A new automatic loop was constructed at this location.
Queensland Railways constructed the signal box to their own design with the addition of an awning.
Although Glenapp signal box looked like a NSW Railways Type E, it was in fact a standard Queensland Railways timber signal box with the addition of an awning. The signal box was originally mounted on a cast concrete pit. The 1944 extension can be identified with the absence of a pit extension. No landing was provided. RT Taaffe
