You will find the Train station on the left side of the town map. Tap it to learn about the next train arrival and the amount of passengers it will bring. You can upgrade your train station and the train itself at the same time. Upgrade requires bricks, planks and concrete. With each upgrade your train will bring more travellers to the town. At first your train can fit in only three passengers, but a fully-upgraded train will bring 15 travellers to the Fairytale town. Train arrives every 6 hours.
