Re: Underground station extensions

The dev team seems to not care 
I would say, they have no time to care.
If there would be a patch out there that is working to some degree, the likelihood that something like this comes into trunk increases rapidly. But active programmers are rare these days :/
These request is not trivial to implement (but not very hard either). Some checks needs to be added to prevent tunnels being built through a stairway...
I'd certainly support extension buildings that could be built underground (currently they can only be built above ground). I'd also like additional parameters in the dats which allow platforms to be built either only underground or only above ground, e.g.
allow_underground = 1 or 0
allow_aboveground = 1 or 0
This is definitely a good idea.
