In 2017, I made an unofficial transit diagram covering the Oslo region in Norway. The challenge consisted of combining the metro, tram and train network in one single diagram. Five years later, I revisited the project with several improvements:
1. Showing all the lines on every network, thus making it easier to understand the service patterns.
2. Making it recognisable with the official line colours.
3. Compressing unnaturally long distances between stations.
4. Balancing aesthetics and accessibility. The diagram is clear and easy to read with minimal fuss.
Watch the ten minute long video below for a full overview on the design process.
Alternative version with metro line 5 split up with a fictional line 6.
