This is the interactive coaling facility on the Uintah Railway in Carbonera,
Colorado that takes coal in on any gauge track and outputs it to 3 ft gauge
gons at any of the three chutes. There is insuficient clearance for a loco
to take on coal except at the chute that is not underneath the structure.
In the real world there was no provision to store coal above the chutes.
Empty gons were spotted below and trams dumped directly into them. The same
is true of a loco taking on coal. Trams held about 1 ton each. Any gauge trams
can be used by changing the kuid for the three input tracks to the rail only
track of your choice.
Note: To avoid crashing a session I strongly reccomend adding sections of
invisible track off the ends of the three tracks on top as the to unload
trams are trigger points are very close to the ends of the built in tracks.
EDIT: Corrected a clearence problem.
