The best part of Cities Skylines is just watching the city go by, watching trains zoom by, pedestrians come and go from the station. See several trains from different routes all venture into a station or down the express rails. Set to relaxing music, take a journey through the fictional Cities Skylines city of Jajaberg (a mixture of Scandinavian and Australian design) and into the bustling suburb of Tronberring. I have updated the graphics for this, now in 4K (hope to get a new 12gig GPU for Christmas) would will make the experience even better. My city (population 640,000) has more than 80 different train/metro/monorail lines that spread across all 81 tiles.
