Train/Metro/Bus Hub
Trainstation, several Metrostations and a huge Busstation all in one place.
I recommend putting the Busstops where the small trees are, the Metrostations where the large trees are, the Busdepot where the small bushes are while the bushes mark the front of the building and the Trainstation is pretty obvious.
Everything should fit perfectly in the gaps of the road/walkway. Simply delete the dirtroad.
You should only need one Busdepot so you can use the second space for a Park or something.
