yeah. maybe the 2002,2005 we also dont know which one.
OT abit: Trains will usually move in CM when approaching when it rains..But water can easily spray around.. So when flooring is wet, ppl have to be careful and it not, they may slip and fall
But this does not apply to PSR,JUR and YSH for the time being.

Today's afternoon rain... Rain until so epic... A lot of trains sure overrun today right?

CM mode won't overrun in most circumstances.

Not Really. Most Trains i sit always Overrun in the Morning when raining (when its Dark)
Once i sat the C151 At Bedok No Rain. it was fine. Enter Tunnel Come Out, Like DAMN HEAVY THUNDERSTORM, Come Out of Tunnel only got thunder (ruin my recording lol)
Den Driver CM Mode Brake overshot Kembangan station (Can Hear "zzzz" Sound like Gas or air[E Brake???!!??] ) den stop for 1 min. den the TO reverse adjust Position.

From the way you've typed,
I assume that it was an Auto mode. Since you said after the train came out of the tunnel, it is raining.
There is no way a train can switch its mode while moving.
The service and emergency (figures from Wikipedia) braking speed of a SMRT Series 0 (C151) are 2.8 km/h/s and 4.68 km/h/s, so there is quite a big difference, most likely the jerk from the transition of max normal brake to emergency brake will make people fall down.
If there is a constant 'pssh-pssh' sound, likely its from the re-adhesion action, akin to the car ABS (anti-lock braking), the air brake applying and releasing to prevent wheel skidding especially on wet rails.
It would be due to the design that there is little re-adhesion entirely based on regenerative brakes on any of our trains, as the air brakes are also in charge of the normal braking force... A search on videos online will get the meaning.
Notes: Air brake means using the air reservoir for braking purpose, a padded brake is used in this case. The other type would be a disc brake. This is a form of dynamic braking (spent energy and cannot get back).
Regenerative braking (spent energy and can be reused) means converting kinetic energy into electrical and feeding it back into the system at the same time. A long explanation to go in-depth, but in short it saves energy by giving back energy to the electric supply during braking to be spent on another train's acceleration process. This process also enables the train to slow down, and depending on strength of the regeneration, dynamic (air brakes) braking is also necessary to be used together.
There are some trains in the World which has regenerative braking all the way to 0 km/h, the JR East E231 is one. Dynamic braking system is also carried but reserved for emergency and/or regenerative loss.
Our trains have regenerative cut at 6 km/h (thanks to E5�ん for the info) and dynamic braking is used thereafter.
what bus do the bridging service??
sorry little OT
