Inspired by this schematic map of the Sydney Suburban Network from 1969 (June 2012, 2 stars), I decided to create a retro-looking map of the rail network in 1950 in a similar style.

I think you’ve nailed the look and feel of this piece quite well, although – like me with my digital recreation of a 1939 map of the Sydney network – you’ve discovered that modern computer-designed artwork can look way too clean to pass for something made over half a century ago, despite the weathered paper texture you’ve added.

The system still looks very recognisable – there’s a few more branch lines than today and the City Circle is still incomplete – but this map shows the majority of the Sydney Trains network we still use today.
