No there isn't any train stuck at Jurong East.
It was around 7:25pm when I reached Jurong East and I thought it
was just the normal crowd but when they started making an
announcement about the Marina Bay train arriving in less than 6
minutes I started knowing that something is wrong. It took more
than 3 trains to clear the crowd waiting at the middle platform,
and mind you, these 3 trains were all packed to the maximum, you
can't even squeeze in if you want to board.
The first train which carried part of the crowd away came from
Bukit Batok (which was the last station before Jurong East, on the
North South Line). The second and third train came from the
terminal I think, as it approached the platform from the other
direction.
First train, from where I was, approached the middle platform in
this direction: <---------
Second and third approached the middle platform in this
direction: ----------->
I hopped onto the third train.
It didn't end there. The train would stop in the middle of the
journey out of the sudden, with an announcement saying that there
is a train ahead.
When I alighted and saw the arrival screen, all Marina Bay
trains (which include the one I took) were all having an arrival
time of 1 min.
It goes like this:
