Parking Garage System.

and you would not see the cars there , only the income of the parking

and i also need to overwork the json then , but at moment it is hard to do that , because i need a position for every car , i hope Joscha will add something that we just can add 1 position for x cars

Not at moment , but maybe i can do that if the Parking Ssytem of Joscha is complete finished , at moment it is just the first version of that.

Does this now work so it earns money (on Edge where the mod support is in place)? If so, how many spaces does it provide?

No , that is just deco

Will this help increase transit capacity?
