One can see the bag of the air suspension and regular tread brakes - not disk brakes.The disk shaped item on the left axle may be a tachogenerator to measure the wheel speed.

A very beautiful & informative snap. Air Tanks & Auxilary Air Tanks, Wheel Axles & the Groves covered which will join to the groves of the electric motor & lastly Disc brake system.

The technology used in this kind of Couplers is one of the best foolproof technology.

I zoomed up the high res image and the coupler reads "Schaku" which is most likely the name of the German manufacturer. All I know about a Scharfenberg coupler is that it helps in automatic coupling.

Yes, there are instruction and announcements both in Hindi and English - on the stations as well in the trains.

Hope there is also an English version of it.

Looks like a Scharfenberg coupler.

Yes. The catenary maks is similar. Can anyone tell us differences? Thanks!

Seems like the metor uses the same caternary arrangement as the Indian railways.

I did not notice these wheels during my visit to see the prototype. I thought that the basic guidance is by the standard undercarriage being used on the rails. What is the exact purpose of these wheels?
