I can't for the life of me work out how to get any of the vehicles I buy onto a line I set up. How do you assign convoys to a line? Every time I have selected a line, then press "start" in the depot dialogue, a little box pops up saying "Where do I go? You must give this convoy a line or assign it to a schedule before giving it the go order." Any ideas what I might be doing wrong?
1. Select your vehicle
2. Click on the second bar that says <not assigned to line> and select your line, or alternatively press "new line" and make a schedule for a new line
3. Press "Assign Line." The "Serves Line" info below max speed should change from <not assigned> to the line you want.
4. Press "Start"
Note that if you modify your line after you assign it to a vehicle in a depot, you may have to re-assign the line to the convoy, so it is best to do these steps in that order. I hope that solves your problem!
