Delivery of Mail the mail [[File:icon mail.png|16px]] delivered, 2 will earn Money Tokens [[File:token money.png|16px]] will be given. Moreover, mail delivery contributes to the town growth. Post Offices only appear in [[Ages#EraII|'''Era II''']], the Steam Era. During the transition between [[Ages#EraI|Era I]] and [[Ages#EraII|Era II]], several post offices Post Offices will apear appear in each towns accross 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#Advanced|'''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 proceesses processes will begin. The first process takes Mail [[File:icon mail.png|16px]] that has been delivered to the station, takes brings it to the post office and converts them it into 2 Money Tokens [[File:token money.png|16px]] each at a rate of 1 piece of Mail [[File:icon mail.png|16px]] per for 3 Money Tokens [[Game tickFile:token money.png|game tick16px]]per 80 squares of distance traveled.  The second process produces 1 piece -4 pieces of Mail [[File:icon mail.png|16px]] per 2 [[Game tick|'''game tickticks''']], this . The Mail is then sent to the nearby station, ready for collection by a train pulling [[Wagons#Mail|'''Mail Wagons''']] or by [[Road_vehicles#Mail_Vehicles|'''Mail carrying trucks''']]. The number of Mail [[File:icon mail.png|16px]] 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 [[File:e_energy.png|16px|link=Electrification#Electrical_network_around_the_cities]] if you connect the Post Office to your electrical network [[File:e_energy.png|16px|link=Electrification#Electrical_network_around_the_cities]]. ==Post Office Levels==You can see the progress towards next level in the Post Office Info Window {| class="wikitable"!
