Due to heavy rain late December, the soil and roadbed at the
tunnel entrance/exit have became loose, and some SMRT engineers
were seen doing works at the tunnel portal on Bukit Batok
side.
I started seeing them last week, and yesterday (13th) many
engineers came down and trains have to be slowed down at the area.
Notice as follow was placed in the rack at the platform for TOA
reference.
(marker written)Inform TSC when

Such was the notice.
And so was the soil movement so great that you can feel on the
train? Well, I tested out and took 053 train 222 to BGB, and other
than slow entry, nothing else was out of ordinary, neither did
anything happen when I took 074 train 205 back, other than stopping
to 0 speed in the tunnel twice and seeing the engineers waving the
train past. However, the signal 40/0, signaled by a loud beep sound
(I not sure, but I can guess its absolute zero speed command) was
issued after 205 passed the portal and the TOA braked hard. After
which it was reset with communications to 'TSC' and we continued on
the journey.
You can too try out if you are free!
