It's fun to learn about this stuff but wow, that music/sound fx and announcer combo make it almost too hyped up to retain any information.

I'd love to see a Siemens Vectron electric (Freight) locomotive in Burlington Northern Santa Fe, Norfolk Southern or Union Pacific Colors.

Somebody needs to fix the title and your math. Did you divide 25,000 volts by 120 for household voltage to get 200 homes? Voltage is not the unit for power consumption. This is like saying that at 100mph, this train is as fast as 2 cheetahs. The units just don't add up that way.

The four systems are Pentagraph, Third Rail Pickup, Two Rail Pickup and Return with is used with the Pentagraph or in two track territory, and the last one is Diesel. Each country has a different system so the engines need to be adapted for each border.

Third rail is pretty uncommon in mainland Europe for anything other than metros. The four systems he was talking about would have been different AC and DC voltages used in various different countries.

What is a "pentagraph"? The locomotive only has four pantographs. Not five...

It's dumb we cannot agree on one type of electrical system

25 kv 50 Hz is where it is at. The gold standard for electrification.

How silly is that super dramatic music and narration in context with this interesting but rather mundane and non-dramitoc topic? Please stop over dramatizing stuff. You're supposed to be THE Smithsonian!

There are plenty of interesting facts about pantographs that they could have used - like how on high-speed trains, the power lines have to gently zigzag so that they wear the carbon contact down uniformly instead of cutting a groove in the middle, or why carbon is used for the contact in the first place, or the specifics of those four different power systems. But they didn't do any of that - just, "this is a pantograph!" "this pantograph is toast!" "OK, we are lifting the pantograph!"
