			Road stops have 16+4 random bits. Bits 0 to 15 are a property of the station as a whole, and bits 16 to 19 are different for each tile.  To get tile-based randomness, therefore use randbit=10 and nrand of no more than 16 (since only 4 random bits are available per tile).

			Also note that none of the above triggers will actually trigger unless prop. 0D has at least one bit set.  Triggers 01 will be triggered for any of the cargo types set in prop. 0D, but trigger 02 will only be triggered if all of those cargo types have no more cargo waiting. Triggers 04 and 08 are triggered no matter what cargo types the road vehicle transports, as long as prop. 0D is not zero.

			Triggers 04, 08, and 10 only affect the tile on which they occur, as well as the random bits of the station, but not other tiles.

			Because the 'occured triggers' are only stored once per station (not distinguishing tiles or cargo types), adding 80 to
			random-triggers does not make a lot of sense.

	=== Industry tile triggers ===		=== Industry tile triggers ===

	Industry tiles have 8+16 random bits. Accessed through random action 2 type 80, you get 8 tile-specific bits, and accessed through random action 2 type 83, you get 16 industry-specific bits. The triggers are the same for both. Triggers 02 and 04 are triggered for all tiles of the industry at once. Every tile can rerandomise both its own random bits and those of the industry. That is every tile can specify some bits of the industry to ~~rerandomsize~~, and the union of all those bits will be rerandomsied at the end.		Industry tiles have 8+16 random bits.
