What's a city without a train station. We needed a quick way to get to our games anyway. The station comes with 4 overground lines and 2 underground. To date, there is only one line which doesn't go anywhere yet. There is a villager working at the ticket desk, and another in the back office (there was 2, but one escaped and decided to make himselve at home in my house, so I fired him). There are also 3 ticket machines.
The ticket machines are basically dispensers with a button and filled with minecarts. Works quite well I think.
Pictures are from when we first built the city. So there have been some changes to bits.
