Perhaps a business school for training appraiser skill. Consider that shops in the old econ (broken though it is...) used appraiser skill. A law school/library for training persuasion, negotiator, etc?
actually.....
It's possible I could have figured something out for transit but it's clunky at best and impossible at worst.
Workshop: Transit Loading Platform
Workshop: Transit Depart Platform.
Require "metal rails" made out of special iron power axles. You need two rails linking the two stations.
Perhaps a creature called a "minecart" could be placed in a restricted path between the station platforms. It would then travel between the two stations (FPS isses, I know, pathfinding would suck, major problem).
A reaction would have to require a preset number of items as reagents to be placed in the loading platform. These would then appear in the depart platform. The reactions would be "Load 10 X" Where X is any type of item. There would be a load 10 stone, load 10 whatever. Only certain things could be transported this way as listed in preset reactions.
The trick would be:
1.) The minecart "creature" (Needed?)
2.) Requiring a workshop to need power for the "rails" (power axles)
3.) Having reagents in one workshop produce things in another distant workshop.
