This is a prototype map with an interactable Rail Management System screen made
for a TWHL contest.
The idea was dropped but it is functional enough to upload to the TWHL vault as
an example of the dumb things you can do with vanilla Half-Life.
This was intended to be built using TrenchBroom and ericw-tools, VHLT will
complain about leaks because it doesn't handle SKIP textures the same way, NULL
can be used instead.
