If the driver exceeds the speed limit for a section, the train will brake automatically until it is both below the limit and the driver presses a flashing "Alarm" button.
From MRTC:
For ATP purposes the running line is divided into a series of ATP blocks by track circuits. The train is provided with two speed parameters:-
1. The Maximum Safety Speed (MSS), which is the maximum speed at which the train is permitted to travel within the ATP block it currently occupies.
2. The Target Speed (TS), which is the speed which either the manual driver or the automatic equipment should aim to achieve and which is generally the same as the Maximum Safety Speed for the next ATP block ahead.
If the train speed exceeds the Maximum Safe Speed, motoring is inhibited and an emergency brake application is made.
Adding on: Exceeding of Target Speed can be done, as long as you make it below the MSS before you hit the next block, if not EMG brake will be made upon your train.
Hope this clarifies.

This video is sufficient to explain my stance with regards to wheelslipping during braking.

Some of the things there may not necessary applies to our system. As an example:
- Are the ATP block sign placed before the beginning of every ATP block to notify the TO that he/she has to stop/reach the target speed before that point?
I only see a stopped train on the video
