One tip...when you deplane at B check the departures screen for your flight out of A. If there is a symbol that looks kinda like a red dot next to the gate...that means you should DEFINITELY take the train when you to the A concourse.
If you look at this "half map" the red "express train" dot symbol on this map is what they have next to the gate number IF you should take the train once you get to terminal A, if there is NO dot...it is faster to walk to your gate (using the moving walkways/travelators) once you get to terminal A.

When you take the escalators up from the light/sound tunnel you will see the elevated train track/platform area.
If you watch this video:

It mainly shows the fountain but you see the train also at around 44 seconds into the video... The escalators up to the train are visible behind the flight info screens underneath the platform/station area...
