The first reaction to seeing this fantastic MOC by monstrophonic is likely "whoa, there's a train hanging out of that building" followed shortly by some internal calculations of the plausibility of this scenario. The thing is, this really happened. On October 22, 1895, in an attempt to get back on schedule, the driver of the Granville–Paris Express entered the station too fast and when the brakes failed the train burst through the buffer stop and station wall, coming to rest on the street below.
