Pa Sak Chonlasit dam in Lopburi province

Pa Sak Chonlasit dam in Lopburi province

Pa Sak Cholasit dam in Lopburi province เขื่อนป่าสักชลสิทธ์ จ.ลพบุรี. Pa Sak is the name of the river. A small part of dam and reservoir are in Saraburi province จ. สระบุรี.

Accessible from Lopburi by bus 601 (33 Baht, 01.12.2014 10:03 from Narai roundabout to 11:08 near the dam where hwy 3017 turns south). The bus starts in Lopburi bus station and goes to Wang Muang วังม่วง in Saraburi. Ask the bus driver to let you out near the dam, there is no sign (but an arch in the distance) and no water to see, about 1.0 km walk.

There is a van line 14 Bangkok - Pa Sak Chonlasit Dam - Wang Muang.

View from dam to observation tower, museum and recreation area (railway station is behind the trees). 

View from observation tower (labeled as museum, entry 20 Baht, 8 floors) towards dam. In the tower, there are pictures of exhibits from the museum in Lopburi, nothing about the dam. The building you can see is the museum about the dam, free entry.

Exhibit in recreational area:

Various restaurants and shops, this is sunflower root (?) แก่นตะวัน natural and dried (to make tea?) price per bag 100 Baht (same price for natural and dried).

A tram across the dam (25 Baht, 12:15-13:03) leads to the Saraburi side with a sitting Buddha statue.

There is a railway line that goes along and through the reservoir (but not across the dam that holds the water) which is on the title page of "Unseen Thailand" (a friend owns a copy, I have yet to get my hands on copies of both (?) editions, got a table of contents from internet for part 2). 

This line is a bypass in the Northeastern railway line between Kaeng Khoi Junction ชุมทางแก่งคอย and Bua Yai Junction ชุมทางบัวใหญ่. There are 8 local trains that pass the station every day, and 6 of them stop at the station. 

Trains to Nong Khai and Ubon Ratchathani no not go via this line. One fine day I will ride on the local train for the experience (part of a bigger project: I will try to ride train on every railway line in Thailand and go to every terminal station). From observation tower, I could see the part of the railway line on the water, but was too lazy to walk (about 1 km each way). 

Details and satellite pictures here: 
Railway station on google maps.

With the dam begun in 1991 and inaugurated in 1999, the railway line must have been built. But why was it built on a bridge (additional cost compared to land)? And why did they build a railway line that has only 8 passenger trains per day? I did not witness any activity on the railway line, so there are no freight trains.

SRT (State Railway of Thailand) has special trains every year in December to this dam and to sunflower fields in Lopburi and Saraburi province. Poster for this year's trips:

(Between Dec 6 and 28 2014 every Sat, Sun and holiday, total 9 trips. Information from a friend who will go: starts 6:30 am, back at night, 300 Baht.)

  1. 1.aboput the railway: was there before this artificial lake was made-so they had to find a solution for it.
    2. trains to NgHai DO run via this line-some, but mstly the overnight=nothing to see. To Ubon of course not.
    3. on the forum of 2bangkok/.com are tips for riding every passenger line- this is not that difficult, except for 1 stretch which only has 1 goods/mixed/pax train mo-fri and ends at a village without HTL nor travel back (from Surat-some 40/50 kms, intended to go to Phuket). This does mean you often need to use buses from far ends (f.e. Kantang, beyond Trang).
    Also the Supanburi branchline now has the prob of no return, (they once did extra trains when the then PM came from there), but that town is easy enough to find HTL and also to see various things, like the museum built like a dragon.

    1. They could have relocated or abandoned the line, cheaper than elevating it.

      I checked and indeed, two trains to Nong Khai pass the dam at night, but no stop at the station (but in Lamnarai).

      Suphanburi is easy to go to (train in the evening), but inconvenient to return to Bangkok (train early morning).

  2. That BOOK(let) you show the cover of, I ahve at home, there once were yearly guidebooks (just 59/69 bt at 7) to entice Thai to see their homecountry. dates from some 5-6 years back now, I guess.

    1. Now they are scarce, haven't seen them in second hand bookshops. Articles are in Thai with abstract in English.

  3. No handsome young male visitor this time on your pictures ?

    1. There were some dozen Thai adult visitors around and a school class (about 10 year olds) from Ang Thong. Nobody caught my eye.
