An interrupt can name a wildcard signal (any item, any fluid, any fuel, any signal): the train tests the conditions against each item it carries, and the first that passes replaces the wildcard in the target stop's name and wait conditions, so one interrupt sends any cargo to the stop named for it.	`Generic interruptGeneric interrupt`	Dev blog
Since 2.0 a train told to go to a stop that doesn't exist reports "No path" instead of skipping it, and a disabled stop acts as if its train limit were 0: a train already on its way still arrives, and one sent there waits as "Destination full".	`But what if I don't have a ... dropoffDoes it still skip if I disable a stopDoes it still skip if I disable a stop`	Dev blog
A train stop has a priority from 0 to 255, 50 by default and settable by circuit: trains choosing a destination prefer the higher priority, and trains at higher-priority stops leave first. A train the player sends somewhere by hand, or one stuck on the main line with no path or a full destination, gets 255.	`Train stop priorityTrain stop priorityTrain stop priorityTrain stop priorityTrain stop priorityTrain stop priority`	Dev blog
Since 2.0 a train placed from a blueprint switches itself to automatic mode once it is fully built, fuel requests included, so new trains can be stamped down with no setup.	`Easier train dispatching`	Dev blog
