these are the current public buildings i have:
-general store
-police station
-inn/tavern
-minecart station(unfinished)
-park
i dont know what more to add yet, i am building a larger public area in the wealthy area of my city, so things as a library and a hospital don't exist in the lower class public area.

the minecart station isn't finished yet,i have built my city for the largest part on water, so i have to lay tubes while underwater, i't boring becouse it is not visible on the surface^^.
i have laid tracks leading to a stop in the church,inn,police station and ofcourse the station. i have made switches, but i don't have them wired yet, becouse i lack a main grand station, wich i'm going to build in the upper class public area.
i have added a bakery, which is my last building. the only thing left to do is updating the corners of the buildings with tree-wood, wich looks better as just planks
