Hi
I'am recently doing a school project and I need schematics and explanation for the
1)Pantograph
2)Electrical System
3)Electrical and Pneumatic brakes
4)Doors
5)Couplers
I also need a photo showing the undergear of the Siemens Train for both the M car and the T car. If you can, please label the name and the function of the different components.
Thank you.

Not diagrams of the Siemens specifically, but there are plenty of technical descriptions of railway technology at this website:

Thanks but I've already been there
Oh and also does the Siemens AC drive use GTO's or IGBT's?
And do they use Triple Valves or Distributors?
