Pardon my ignorance, but what do the red and yellow arrows on the platform signify? Do the passengers know its meaning?

Karan, the doors of the DMRC rakes stop exactly where these arrows are situated. The red arrow is to indicate to the travelers inside the way out and the yellow one is to indicate to the people waiting the way to boards the rake. This was done so that there would be no inconvenience, but since this is India hardly anyone follows it. This inconvenience is deeply regretted!

Apu sir, any specific reason for this arrangement? Can the same panto be used for OHE cable and rail? Also the height between top of coach and OHE looks very less.

The rail type OHE conductors are common in Tokyo's Metro trains. One of the reasons for having a rail-type conductor is reduced hassle of maintenance of OHE equipment inside the tunnels. Rail-type OHE is easier to install and nearly maintenance-free.

Let me point out one thing. This rail type structure only supports the OHE wire. The metal rail does not generate the electricity if that is what some of you are thinking. And yes the same pantos can be used for this too.

Ah Sid! No one ever said that metal rail can "generate" electricity. Generation of electricity is the job of thermal power stations :-). Metal rail can only feed electricity. As for your statement the "rail type structure only supports the OHE wire", it is not clear what you mean.

Rail type structure supports the OHE wire, i.e. carries the wire.

The track has no ballast (understandable, even KR has ballastless sections) and no sleepers too! Is it that way only on underground sections? Also, where does the track derive the stability that ballast and sleepers provide in the absence of both?
