Toowoomba Range rail tunnels lowering
John Cleverdon <johnc@...>
A little off-topic, but as some of you may be aware, the heritage rail tunnels in the Toowoomba Range are to be lowered to allow higher-clearance trains through them.
A professional magazine I get mentioned use of laser scanning as part of the lowering of these tunnels.
