Imagine manually rotating an entire train locomotive like this. Old engineering was incredible.

This is a Deutsche Bahn Class 612 tilting train in Germany.Modern tilting train technology was widely developed and tested from the 1960s onward to help trains handle curves more smoothly and quickly by leaning inward during turns, reducing the sideways forces felt by passengers.The technology is especially useful on winding and mountainous rail routes, where building entirely new high-speed lines would be difficult or expensive, and it is still actively used today on many rail networks.📹kilist
