I got a question:
What is the ECP in station means (Not the expressway -- East
Coast Parkway hor!)
The image was snapped on Paya Lebar CCL, near the exit towards
SingPost / nearest to existing EWL exit / the exit that leds to a
bus-stop that has bus services terminating at the East (Eunos -
154, Changi Airport - 24, Marine Parade -43, 76, 135, 155, etc) The
thing next to it, B1C05, is an ECP of dunno what. Does this tells
that the middle track of Paya Lebar was at least
planned to extend to somewhere else, even though most likely it
would be Marine Parade?

Future Existing Connection Point (My Guess).
My reasons to support my answer :
