(Back in) Time Tunnel
I love it when people find old transit maps still in situ at stations. This Northern Line map at Embankment dates from sometime prior to 1999 (the year that the Jubilee Line platforms at Charing Cross closed), but is still in place today — this photo was taken on February 21, 2013.
Note also the beautiful 1914 green glazed tiles next to the map.
Luxembourg Rail Map, 1999
I guess when your entire country is the size of a large city, you’re allowed show your rail network in the form of a subway map.
