Editing v0.31:Wagon

Wagons '''cannot''' cross [[door]]s{{verify}} (even if the doors span an area ordinarily wide enough for the wagon to pass) or upward or downward [[stair]]s, though wagons can move across downward stairs covered by a [[hatch cover]].  Obstructing [[boulder]]s must be smoothed ( {{K|d}} - {{K|s}} ), and [[tree]]s must be cut down ( {{K|d}} - {{K|t}} ).  [[Shrub]]s do not obstruct wagons, and neither do [[ramp]]s, [[bridge]]s, [[road]]s, or [[floor]] tiles. (However, ramps covered by a [[hatch]] do obstruct.)  The impassable tiles of [[workshop]]s and other buildings will obstruct, but the passable tiles of those buildings will not.  Any buildings which are normally passable, including [[restraint]]s and [[trap]]s, will not obstruct wagons either, nor will creatures, whether restrained or free.

After a trade depot is built, you can use {{K|D}} to check wagon accessibility. The decisive element is that you see the 'depot accessible' message on the right. Accessibility is calculated from your depot, not the edge of the map. Even though you see a green area around your depot, it may not be accessible. You need to make sure the path extends all the way to some edge of the map. The display is somewhat misleading in that a one tile wide green path is sufficient for the 3 tile wide wagons; the green {{Raw Tile|W|2:2:1}}s represent only the ''center'' of a wagon although the whole 3x3 can fit around it - so a three-tile wide path, which can fit a wagon, will only show up as one-tile wide line of {{Raw Tile|W|2:2:1}}s.  When the route they would take goes over hills (ramps), it's hard to eye whether it is continuous all the way to the edge of the map, so be sure you see the words "depot accessible" on the depot access screen.
