Hi,

I found this short 2+ minute video quite fascinating.
I have been researching drive systems for early electric locos, and found this clip.

The video can be viewed at https://www.youtube.com/watch?v=iHcWrWWlKe4

Maybe you will like it too.

Incredible drive system. It even took a misaligned turnout without any problems. Look at the turnout at 0:30. How does any train make it through such a turnout?

I know the whole thing is an artist's conception, but the artist that came up with it, must have no idea of how a train runs, or how turnouts work.

Hi,
The video is about the drive system.
The track is merely as you say "an artists conception".
I too noticed the switch blades were not aligned correctly, but in my opinion it does not detract from the message.

Mind you, there is nothing new under the sun.
Which is why I mentioned E04 (1933) and E17 (1927), both had a flexible drive system (made by AEG or Siemens too).
I think of it like a motor vehicle CV (constant velocity) joint on the drive shaft.

Not completely new, but miniaturization allows solutions that were not possible in the last century.

For high-speed trains the unsuspended masses have to be as low as possible. The ICE 3 has motors mounted between truck (single suspension) and car frame (double suspension). And all this under the feet of the passengers.
All fast locos have suspended motors and need a power transmission that allows for some movement. E 16, E 17, E 10.
