. @notjustbikes @RM_Transit 28 minutes they finally get to the Nueiwmaarkt riots and why the metro is the way it is. Because line 50 and 51 were not built as metro. They were snel tram. In fact as recently as 2017 the lift at Sloterdijk said "perron sneltram".
Noord Zuid line needed the technology to bore a tunnel through swamp. That's why the original lines were cut and cover.
