(This is historical picture kept here just for a reference)
Both the Post Office look and its processes have been updated during the large city update in June 2021
Post Offices on the map will trade Mail between themselves, or rather between the stations having a Post Office in their catchment zones. Delivery of the mail will earn Money Tokens . Moreover, mail delivery contributes to the town growth.
Post Offices only appear in Era II, the Steam Era. During the transition between Era I and Era II, Post Offices will appear in each towns across the map. Post Office has fixed reserved size of 2x1 squares even if at level 1 the actual building is only 1x1.
Mail delivery follows the same rules as passenger delivery, depending on the Passenger Destination parameter in Game Settings. The transfer between different trucks and trains happens automatically similarly to transfer of the passengers. Do not use Full load / Unload commands for mail.
Once a post office is within the catchment area of a station, two processes will begin. The first process takes Mail that has been delivered to the station, brings it to the post office and converts it into Money Tokens at a rate of 1 piece of Mail for 3 Money Tokens per 80 squares of distance traveled.
The number of Mail produced depends on the level of the Post office. Post office has 3 levels changing automatically as your city grows. Moreover, at level 3 there is an extra electrification bonus if you connect the Post Office to your electrical network .
