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?

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...

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