After I posted about this fantastic 1978 book celebrating the Moscow Metro, reader Martin Vrba let me know that he had a very similar contemporaneous book about Prague’s Metro, and was kind enough to send along some photos.

Of particular interest is the first map, which shows projected extensions to the 1978 system (shown as solid lines) all the way up to 1990. There’s a few differences, but it’s basically very similar to the system as it exists today. Also, there’s some changes in station names between then and now – the Soviet-era Leninova is now Dejvická, for example.

There’s lots to look at in the other pictures as well – plans of routes, cross-sections and elevations, even a diagram of the tunnel boring machine used.
