As far as I can tell, answers are as follows: 1. Allowed if vehicle has "Go to depot (stop)" order iI said it's ok to make a vehicle to START acceptance - that must be stopped after or make to the destination, to unload or transfer don't stopping vehicle leads you to breaking the "cheating" rule, and an admin can act as he want 2. Allowed if vehicle is stopped I fucking hate to repeat myself 3. Allowed but cargo cang only be loaded from Pentwood West later. each vehicle on OpenTTD must have a purpose on the game: Load at one place and unload/transfer on another place as understandable, the unload must be on a place that accepts the cargo and transfers must have a use (on the moment, taken to other place - or to use later)
