Train Station

The train station is a relatively new feature unlocked at level 21. Each train has one wagon not counting the locomotive. A second can be unlocked with 10,000 coins. A third wagon can be unlocked permanently for 15,000 coins. Each wagon represents a demand that can be fulfilled to earn XP, coins and a special key.

Three keys unlock a train station chest, which might grant:
 * 1 free barn upgrade
 * 1 photo slot
 * 1-3 tools
 * 7-14 rubies
 * 25% or 50% growth increase for trees and fields for 4 hours
 * So-called 'adventures', in which the protagonist and one of the girls venture beyond the villages range. Adventures still take up one photo slot.

There are the following adventures for now:
 * "City Boy, Farm Girl" with Mindy
 * "Dickumentary" with Laura
 * "Sproutcock Mountain" with Ginny
 * "Who Cums in First Place" with Sarah
 * "Good moaning, Emma" with Emma
 * "2vs2" with Una, Diana and Mindy
 * "Lord Dreadcock" with Jane
 * "Tami drives a Musclecock" with Tamiko

Keys don't expire if you do not load any wagon on the next train. If you already have two keys and a train arrives with two rewards, claim the first key, claim the chest and then claim the second key - which will be the first for a new chest.

An empty train arrives with a timer of 16 hours until it leaves on its own. If you successfully fulfilled at least one demand the train provides, you can send it away early. No matter if it left empty or with your products, the new train arrives two hours later. If you fulfilled a demand, the trains arrival grants you your rewards and the new 16 hour timer starts once you claimed them. You cannot dismiss the train early if you don't fulfil at least one demand.

You can load a wagon one piece at a time or via 'load max', in which case all that you've got will be put into the wagon, up to the demanded amount. Beware: You cannot regain loaded cargo by any means.
