This is a large interactive coaling facility that takes coal in on std
gauge track (stopped unload) and loads std gauge tenders at any one of 6
chutes (stopped load) with animation, smoke, and sound effects. Note
there is extra invisible track off the back end of the delivery track.
This in case you shove a cut of hoppers up the ramp a bit too enthuastically
and overshoot the end of the visible rails. It can't be seen in Driver but
this way you won't crash your session. Many thanks to Dale Pattee of bsnteng
inc. for the script file to make it all work
