Specifications & Design Details

[ncr]

We have read many figures about the subway and also details about the station designs, sizes, depths etc.

But one fact is still missing, as far as I know:

I was wondering what are the distances between the stations, especially the shortest and the longest one between two stations?

[ncr]

Is there any information on when they will introduce the remaining 9 station symbols?

So far, only the stations from Hualamphong to Rama IX have their own distinctive logos (as seen at http://www.angkor.com/2bangkok/2bang...ysymbols.shtml).

The others, I noticed, have coloured bands running along the top of the walls in the platform areas (I saw blue, yellow, orange, red) - is this the same colour code that Wisarut wrote about in the abovementioned article?

1) Blue is for interchange
2) Red is for commercial areas
3) Green for parks
4) Orange for areas of moderate density
5) Yellow for the Royal family
6) Cyan (or azure) is for waterways

[Wisarut]

Khun NCR,

The average distance is about 800-1000m. The longest distance would DEFINITELY be from Kamphaeng Phet to Bangsue and the shortest one would be Samyan to Silom or so.

So this question has been answered on the main page today:

No further symbols for the rest of the stations - July 9, 2004

2Bangkok.com contacted MRTA to ask about the lack of subways symbols north of the Thai Cultural Station. Their Public Relations department said it was because from Hua Lamphong to Thai Cultural Center there were "special or important places" to base the symbols on, but there are "no special or important places from Huay Kwang to Bang Sue."

We asked if the reason really was that two different contractors worked on the line and the one that worked on the northern section did not participate in the symbol project. MRTA's reply: "something like that."

We finally asked if there were any plans to create further symbols for the rest of the stations. The answer: "No. Construction is finished."

It is not surprising no further emphasis is being put on the symbols. The existing symbols were poorly received and are not being used at all in signage or maps.

[ncr]

I found that no, there's no colour scheme (according to location) for the 9 stations without station symbols.

Instead, each of them apparently has its own colour:

Thai Cultural Centre - Blue
Huay Khwang - Orange
Sutthisan - Red
Ratchadaphisek - Pink
Lat Phrao - Light Blue/Turquoise
Phahonyothin - Yellow

(Didn't get any further to check Chatuchak, Kamphaeng Phet and Bangsue today.....)

[Wisarut]

Khn NCR,

Blue Stripe for Chatuchak Park station -> Due to the Interchange Station

red Stripe for Kamphaengphet station due to the weekend market and or Tor Kor

Blue Stripe for Bangsue due to the Interchange with both Northern and Southern Train at Bangsue

[ncr]

Khun Wisarut,

Hmmmm..... so colour code for the last three stations again? Doesn't make sense.

And what does Tor Kor stand for?

[ncr]

On several occasions I took the times between stations with my watch (from the moment when doors closed until they opened again).

Here they are (in minutes and seconds):

Bangsue - Kamphaeng Phet......................1:24 [1:33]
Kamphaeng Phet - Chatuchak....................1:13 [1:21]
Chatuchak - Phahonyothin.........................2:11 [2:23]
Phahonyothin - Lat Phrao..........................1:38 [1:40]
Lat Phrao - Ratchadaphisek.......................1:37 [1:41]
Ratchadaphisek - Sutthisan........................1:24 [1:29]
Sutthisan - Huay Khwang...........................1:35 [1:42]
Huay Khwang - Thai Cultural Center..........1:49 [1:43]
Thai Cultural Center - Phra Ram 9..............1:28 [1:30]
Phra Ram 9 - Phetchaburi...........................1:28 [1:22]
Phetchaburi - Sukhumvit.............................1:37 [1:36]
Sukhumvit - Queen Sirikit Center................2:00 [2:00]
Queen Sirikit Center - Khlong Toei..............1:34 [1:36]
Khlong Toei - Lumphini................................1:21 [1:21]
Lumphini - Silom..........................................1:2 0 [1:23]
Silom - Sam Yan..........................................1:13 [1:16]
Sam Yan - Hualamphong.............................1:43 [2:02]
TOTAL............................................. .......... 26:35

Square brackets []: times taken on a different occasion

Of course this is not an exact representation of the distances between stations as the speed may not be constant, e.g. sometimes there are sharp curves in between stations (Bangsue-Kamphaeng Phet, K.P.-Chatuchak, Chatuchak-Phahonyothin, Lat Phrao-Ratchadaphisek, Queen Sirikit Center-Khlong Toei) where the train has to slow down. But it gives quite a good impression nevertheless.

One and a half minutes seems to be the average value (1:34, to be exact). The Rama IV stretch of the route has the shortest distances between stations. Kamphaeng Phet - Chatuchak could be even shorter than Silom - Sam Yan, considering the former includes a curve, the speed thus being lower.

So Khun Wisarut, Bangsue - Kamphaeng Phet is definitely not the longest one!

Anyway, this shows that for longer journeys, you can roughly estimate 2 minutes per station traveled (incl. time when train is stopped - usually only 20 seconds), which would add up to 34 minutes for the whole trip.

That again, at a total length of 20 km, makes an average speed of 35 km/h (including stops), as stated in the subway specs (and 45 km/h for the time the train is actually in motion).

I presume the Or Tor Kor flower market, right across the street from Chatuchak market.

[admin]

Or Tor Kor is a high-so market across from Chatuchak Market--almost every time you visit you will see a celebrity shopping--the market itself looks like any other Thai market, but the quality (and price) of the items displayed is much higher...

A reader writes: "I have just returned from an extensive trip through Thailand and was amazed. Thailand is a beautiful country with a deep respect for its own cultural heritage, a joy to travel in. Here in the US I represent a small group of people who are trying to get our local governments to implement mass transit in our own city. A question has been raised concerning the width of the standard subway rail- is it the same 3.2 meters found on the railroads in Thailand? What is the diameter of the subway cars? These questions would provide much needed information, thanks for your help!"

[Wisarut]

The following is Skytrain technical data I obtain from
Trainweb as well as Subway technical data from Siemens (Thailand): (tons here is metric tons 1 metric ton = 2240 Lb)

Yoiu better contact with Siemens (Thailand) for this technical issues since Siemens has produced both Skytrain adn Subway rollign stocks.

In a final step and in order to finish this approach, now that we have the average speed, we can of course calculate (hypothetical, approximate) distances between stations (i.e. from center to center). This assumes that the speed is constant (which, in reality, it isn't).

Bangsue - Kamphaeng Phet.......................1053 m
Kamphaeng Phet - Chatuchak......................915 m
Chatuchak - Phahonyothin.........................1643 m
Phahonyothin - Lat Phrao...........................1229 m
Lat Phrao - Ratchadaphisek........................1216 m
Ratchadaphisek - Sutthisan........................1053 m
Sutthisan - Huay Khwang...........................1191 m
Huay Khwang - Thai Cultural Center...........1377 m
Thai Cultural Center - Phra Ram 9..............1103 m
Phra Ram 9 - Phetchaburi...........................1103 m
Phetchaburi - Sukhumvit.............................1216 m
Sukhumvit - Queen Sirikit Center................1505 m
Queen Sirikit Center - Khlong Toei..............1179 m
Khlong Toei - Lumphini................................1016 m
Lumphini - Silom..........................................100 3 m
Silom - Sam Yan.............................................91 5 m
Sam Yan - Hualamphong.............................1292 m
TOTAL............................................. ..........20,009 m

Average = 1177 m

When we factor in the average station length of 224 m (according to the stats published on 2bangkok.com), that makes 953 m between station ends, which corresponds to what Khun Wisarut said above.

Halo, Bangkok,

Below are the official subway route network names of the stations from MRTA, released to your Thailand tourism board office in Orchard Road, Singapore, and I got a copy from the office yesterday:

Bang Sue - Kamphaengphet - Chatuchak Park - Phahon Yotin - Lat Phrao - Ratchadaphisek - Sutthisan - Huai Khwang - Thailand Cultural Centre - Phra Ram 9 - Phetchaburi - Sukhumvit - Queen Sirikit National Convention Centre - Khlong Toei - Lumphini - Si Lom - Sam Yan - Hua Lamphong.

My questions: How many times have MRTA changed the names of these stations ? Why aren't there fixed spellings to these Thai names in English ? I feel they should remain as they are now and not change further. From this episode, I can conclude that Thailand has developed its own variant of English, called Thai English, ie. I call it Thailish, in short, just like Singapore has Singapore English, or Singlish.

[Wisarut]

Khun Gyanc,

The main problem you mentioned is ACTUALLY the Romanization problem since many of Thai people HATE the
official romanization scheme imoposed by Royal Institute (www.royin.go.th) ...

Therefore, they just come up with romanizxatioon scheme to fit their tastes! That it!
