I recently came across two extremely cool videos while preparing lectures for my transportation geography course. It is pretty cool to see the development of the regions around the transportation network while the network itself remains pretty much unchanged. Worth a quick watch!
The first video depicts the London to Brighton Train Journey for three time periods. In 1953, the BBC made a point-of-view film from a London to Brighton train, 30 years later (1983) they did the same trip again, and again 30 years after that (2013).
The second video is from the Vancouver SkyTrain, with older footage (1985) from BCRTC/Translink, and newer footage (2013) by Celgen Studios. You can get the original Translink footage from here.
