pantograph

The connection to a third rail is not a pantograph.

Just put a pantograph on top like electric trains.

The thing that connects a train to overhead wires is called a pantograph.

Jefferson's pantograph goes back well before his time.

This is also why high speed trains can only have one or two pantographs to collect power.

American Type Founders used a pantograph to cut matrices from large engraved patterns.

Didn't realize you're on HN. Your channel is great!Things like the pantograph make me think about computation as a physical process.

We need a separate right of way, with modern, HSR ready stock and pantograph ready lines for passenger traffic only.

Interesting especially the way the use the pantograph to do the charging well away from the passengers.

Induction charging, connection points underneath the car, pantograph.

The most limiting factor is the pantograph/catenery contact; as speeds go up the wire has to be kept at a higher and higher tension to prevent the train catching up to the standing wave it creates in the wire.

One quote that stuck with me is "On reaching the 500 km/h mark, the camera controlling the pantograph condition already shows a continuous electric arc" - you can imagine that under these conditions the wire will wear down much faster than with "only" 350 km/h.

> is there a reason cars don't just have a single blade that goes straight acrossSome vehicles have pantograph wipers which work horizontally, however that's a more complex design than the usual simple pivot, and you can't "park" the wipers out of view when they're not in use so they're more obstructive.
