Do you mean like this? http://www.youtube.com/watch?v=O2oImyCRnpk
The pitch of the deceleration of the train goes very low.

Do you remember the trainset no.?
055/056 also has weird motor sound at the first 2 carriages of departure.
097/098 also has weird motor sound.
This is for C751A... 025/026 has a weird motor sound when decelerating...

I din't see any new video.
If you try to take NSL, you can hear the weird the motor sound if you notice and listen.
In contrast, EWL does not really hear this sound.

Ya I haven't upload, busy nowdays.
If the sounds are coming from the motors, then no matter which line the train is travelling on, there will be such sounds.
For the video on the second post it would most likely be caused by worn bearings in the motor or along the connecting rods.
Faulty motor sound wise, many things can go wrong in the motor. Shall not elaborate too much, but basically it has to do with windings and bearings inside the motor. After some time of wear-and-tear, strange sounds will start to emit and its time to send the motors for a health check.
Other than the motor, voltage controllers/regulators (GTO and IGBT controllers, most commonly used) may also emit irregular sounds if they are of a unhealthy condition, but normally these non-moving parts, when emitting noise, will deem a bigger problem than motors.
Last but not least you have flat-wheels...
Saw 047/048 ytd. The weird sound is very obvious from the middle cars.
another weird motor sound
035/036, when i hear from the int
025/026 C751A - http://www.youtube.com/watch?v=k6hKEOvQRQo
