Questions on MRT/LRT

I got a question:
If a train do overnight parking @ overrun, such as @ Pasir Ris, then will there be a TO in that train, and does the TO walk to tracks to return PSR or just left the train "to die"? How the train return to depot / service in next day? Will a TO go all the way to overrun and drive the train?
For EWL/NSL trains don't do overnight parking on overrun tracks.

IF they park at overrun tracks, one thing you all need to think of?
Can the TO get off??

Thanks pals, would u mind advising what the other indicators (prob 6-8?, sorry can't recall all the "titles" on them), and the 2 meters, at the same location represent, please. Coz when i'm riding in the carriage, it's interesting to see them turn on & off.

I'm not sure. Only some
Power on - As long the train is operating, it will always be litted
???????? - Accelerating, not litted means "coasting"
Air-con Fault - If air-con spoil, light will lit
Brake fault - Brake need to be recharged/resetted

Oh, so you mean that for EWL/NSL, only if a train is faulty, they might be sent to overrun tracks and they will return to depot on the very same day?

If it is peak hours. During off-peak hours. A DNB train will tow the faulty train back to depot.

Yea. Then after train service ends a train (could be a normal train or maintenance train) will pull it out and send it back to depot.

If not you will see

Air-con Fault - If air-con spoil, light will lit
Brake fault - Brake need to be recharged/resetted
Acceleration Current - On when train accelerates
Braking Current - On when train using motor brakes
Brake On LOCAL - On when speed limiter is on or when train using friction brakes
Brake Off LOCAL - On when speed limiter is off
Power On - On when the motors are on
Power FAULT - On when motors in for that car is faulty
Line Volt - On when train is in contact with 3rd rail -

1. No, but the tracks do
2. Why is it bad? It works pretty well.1. Then how do the trains get protected against lightning?
2. I didn't say it was bad. Do all cabins run at same power?
Using this configuration, there is additional load on the second carriage.
And so, when it rains and the tracks are "slippery", the train "slips".(Mainly happens on C151)

what is the speed limiter?
Are there any "hand brakes" for trains?

Motor brakes stop the train by reversing the motor. When the speed goes low enough it switches to friction brake.
Hand brakes? Emergency brake lorh.

1. Like a car.
2. Each car takes in power from the third rail. Low voltage control signals are sent from cab to each cars.

Always wonder, we always see flashing/blinking lights at the end of the station near the train driver when he stops the train.
What does those flashing lights mean? and the front of the train has a single yellow light too, what is it for? -

If it's litted up, and also blinking, it means that the train is operating in "RM", if it isn't on, it means it's just in "AM".

Wow. Thanks yellowflip999 and willis_chong (Y)

I mean something that ensures the train doesn't move at all when in station.

Full service brakes is applied. That's normal friction braking applied to the maximum possible.

I jus ony noticed tat the ccl Paya Lebar stn got 3 platforms.Wat is the middle platform used for??

Short working trips and overnight parking.

It was originally planned to be an extension to connect Marine Parade and add an interchange in ERL (ERL is so far the loniest line, has the least interchange based on the announcements). But some people claimed the land around Paya Lebar was too soft to handle such design, so may not be implemented such extension soon.
So for now, it is used as what Willis said.

If it was originally for ERL, then what's the use of the cross-overs before Paya Lebar?

If you don't know what it is used for, don't go around spouting nonsense.
The middle track at Paya Lebar Station has not, and will never be extended to the future ERL. It is meant as a standby track for SMRT to park a train there in cases of breakdown, or during peak periods to operate shortworking trips starting from Paya Lebar Station.
This will be the case for all future RTS lines, unless Planning Division at LTA decides to change the doctrine, like the recently annouced change in thinking for the provision of future RTS lines.
DTL 2 and DTL3 will also have this feature.

DTL 2 where got middle track? Slidings yes.
Based on 1996 LTA white paper, the Circle Line was to be an LRT and it does not turn towards Dakota but terminates at Marine Parade. Most of the details in this line was not changed except the LRT -> MRT and instead of going towards Marine Parade, it detours to Dhoby Ghaut. Dont forget that ERL has lack of interchanges and it is almost certain that this was considered, maybe not implemented at all due to soft soil only, and thats all.
To Flip: Whats the use of the crossovers before Jurong East from Clementi WB?
