At the foot of the building where I live there's a railway tunnel. Until the mid-70s a few service trains still rolled from time to time, provoking a kind of heartquake which afraid nobody, at such an extent that I once lived a real low range earthquake and was the only to remain cool as I hardly noticed anything.

Service diesels replaced the steam but the pressure and steam relief chimneys remained. Until I was 10, when hearing/feeling the rumble everybody rushed to the windows to look at the steam flowing.

That railway's named la Petite Ceinture, the Little Belt, that runs all around Paris since mid XIXth, used for passenger and industrial but also military purpose, the train being never far of the Fortifications that enclosed Paris then.
Unfortunately no project to use these rails again reached fruition and the stations have been sold, most have disappeared or at best transformed into bars or rag shops for fortunate teens and their parents.
Terrains along the track when at open air have been transformed into private gardens.
