Train Specs questions...
-
Hi,
This might seem to be a pretty redundant question... in fact, it is a redundant question. I am just curious: what is the height from the floor of the MRT to the horizontal bars on which the handgrips are attached?
Really redundant, but just interested to know... that's just me lah... always want to know such irrelevant facts.
Well... thanks!

Floor to handrail centre 1930.05mm g6 tolerence, at 25 degrees celcius.

Ah... 1.93 metres? That's quite high up... didn't really expect it to be so high. I guess my ability to judge height is greatly in need of tuning.
Anyway, how often do you see people with their heads touching these bars, or exceeding it? I have only seen it three times... these people can really see from one end of the carriage to the other without much obstruction. -
no lah. mai di siao siao.
it should be around 1.85m. -
Take the north south line stretch especially between orchard and somerset. Alot of ang mos need to bend down to even enter the train..Originally posted by q0652227:Ah... 1.93 metres?

7cm not a lot. Anyway, the old SMRT website had a lot of train specs related stufff like length of train and so on, but i dunt tink the new one got

Hmm... yah... I remember those information. They are no longer on the new site? Well, at least Wikipedia and sgWiki has them, although, of course, they do not provide this horizontal-pole-distance-from-ground information. Haha...
1.85m seems more like what I would estimate. I actually made some bars in a 3D program, and placed some humans inside (actually, just skeletons). I made one human my height, and raised the bar to 1.93m away from ground. Seems a bit too far from my head. I lowered it to 1.83m; a bit close. So, I raised it by two centimetres, and it seems ok now.
But it could very well be 1.93m. -

Haha... just one of my make-no-sense wish to find things out... even if the thing I am trying to find out does not have much importance.

Ok... along almost the same line as my previous question: How tall are the MRT's doors (the doors allowing passengers to board/alight)?
Haha... yet another trivial question... you would think I am trying to build a 3D model of the train or something. Actually, I am indeed thinking of doing it... haha... -
It will certainly take up lots of time, if you make 3D. Normally, I make MRTs with paper and paper tracks and it takes me like 4 hours.Originally posted by q0652227:Ok... along almost the same line as my previous question: How tall are the MRT's doors (the doors allowing passengers to board/alight)?

Yah... it is time-consuming indeed... especially if the final product is to look as realistic as possible...
So, anyone knows the height of those doors? -
Can you post some photos of your MRT paper models?Originally posted by SBS9889U:Normally, I make MRTs with paper and paper tracks and it takes me like 4 hours.
We would like to see your work.

Its not MRT actually, its a LRT for my fantasy train company:Originally posted by C751B:Can you post some photos of your MRT paper models?

can be easily solved if u bring measuring tape and board one train to measure....Originally posted by q0652227:Yah... it is time-consuming indeed... especially if the final product is to look as realistic as possible...

Haha... I actually thought of bringing a measuring tape too; however, it would look extremely strange if I were to board a train, and then starts measuring the train in front of other passengers...
Well, perhaps I might do it. If you see a passenger with using a measuring tape to measure the train, that passenger will most likely be me... -
Tell you what : Take the train at late night (like after 2300) then there will be less passengers and disturbances for you.Originally posted by q0652227:Haha...

I actually asked SMRT about this question and they say they cannot giv the specs due to security reasonsOriginally posted by q0652227:Ok... along almost the same line as my previous question: How tall are the MRT's doors (the doors allowing passengers to board/alight)?

actually it depends on location la.. even after 11pm train also packed to the door, all the late shoppers rushing home..Originally posted by SBS9889U:Tell you what : Take the train at late night (like after 2300) then there will be less passengers and disturbances for you.
go marina bay lor, can play physics experiment also, throw rubber balls... -
I only tried measuring trains in Japan, where they are more used to these weird things.
Measuring a train, taking tons of photographs and asking the train conductor about the specifications of the train is not considered abnormal in Japan. They are more than willing to tell you.
Some extra sharing, just bought the book I have been 'chasing' after for some time, on the 25th April 2005 train derailing disaster at Amagasaki, Western Japan.Its really a good publication as it provides vital information about physical effects as the train enters a turn, many pictures and diagrams. All of it is in Japanese, but I would still consider it a good buy as Japan is more or less the 'train paradise' in Asia and in the world. -
So, is that possible to ask KAWASAKI about the specifications of the MRT trains?Originally posted by jetabt767400:Measuring a train, taking tons of photographs and asking the train conductor about the specifications of the train is not considered abnormal in Japan.

Not very possible, as Kawasaki or any other companies would look on this as trade secrets. Information would be made known when they are supposed to be. Otherwise we would have to wait or try to search on our own. However, many info about these trains were already made public.

To my understanding, the maximum speed of the trains are set at 80km/h. This works like the speed limiter in cars and all vehicles in Singapore. The true gearbox maximum should be around 100-120km/h, but it is not necessary as acceleration is not fast. Gearbox is made by ZF.
The weight of the car is indicated as 30700kg per car, but we do assume that for motor cars it is more heavier. The arrangement of power is 4M2T, meaning 4 motor cars and 2 trailers, but they are merely the front and rear most cars, with controls.
Built around the Japanese system of ATO (Automatic Train Operation), the 'driver' does not really need to control the speed, but the train is accelerated to the maximum permissible in that zone. If there is a train in the zone ahead, the train would start to decelerate in command increments of 10km/h, until 0. Hence on normal operations, the 10 lights from 0 to 100km/h (I peeped the maximum speedometer reading) would light up.
These information are no means classified, but some enlightenment from my research on trains. I am more into Japanese rail system although you can tip me on other systems worldwide. -
I can only find the train diagram of another Kawasaki EMU,
C321 from TRTC(Taipei Metro, Taiwan), which is similar to our C151.

Thanks for sharing. Anyway these designs by Kawasaki company are one of the best I have seen. Metro trains in Tokyo or in Japan have the same problem; they are too lightweight, making them prone to derailment. Weight is sacrificed for acceleration, whereas speed is not the real demand in this case.
Bullet trains have the same weight as our MRT train, about 30-35 tons. This characteristics, plus the standard gauge of 1435mm makes them safe.
Many trains in Japan weighs like 24 to 26 tons, which is considered light. At high speeds like 120-130km/h it becomes very dangerous. Examples are the Series 207, 120km/h (which image was tarnished by the 25th April accident last year at Amagasaki) and Series 223, which maximum speed was 130km/h, the highest in all the 'local' trains in Japan. Series 223 runs on Special Rapid services, which I have tried when I was in west Japan. I too took the Series 207 (even the immediate sistership to 207-17, 207-16, which was the first car in the Amagasaki accident) and found that 207 have the most lateral movement, like shaking from side to side, enough to throw a person off balance!
The first time I took Series 207 was in 2004, then in December 2005 when I visited Japan again, I took the Series 207 puposely to check on the conditions of the trains after the accident. Drivers of the 207 trains (I presume) were briefed not to exceed 115km/h, so I never saw the real capability of the train. But Series 223 was different, as there had been snow in the area and delays were frequent, drivers drove right up to 130km/h, sometimes exceeding it! However, I am lucky to have survived overspeeding trains, taxis and buses, but accidents would not happen when such things do not at the first place!
