The first unofficial MetroX map I made was based on the railways here in the Netherlands, and as such is based on official maps of the Nederlandse Spoorwegen, the Dutch railway company. All of the lines are true to life, you could actually travel using these lines, although the more south-east you get, the more likely it is you need to transfer.
