Feature request title
Build expanded vehicle depots
Description
For more diverse airport operations, I want to be able to build not only a terminal,
but buildings for other purposes. One of these buildings would be the Expanded Vehicle Depot.
What makes this building different from the existing Vehicle Depot?
You build a building just like building a terminal, but instead of being a terminal,
it allows me to place parking spots for vehicles (Different sizes).
Why would I want this?
- It allows me to decide how big the depot should be and how many vehicles it holds
- It allows me to (in the future) add i.e. a staff room for the vehicle drivers, or a maintenance spot, or a refuel spot
- It lays the groundwork for tenant buildings (See my other feature request)
