The existing infrastructure for the Dhaka-Chattogram railway can be used to operate the high-speed train service, the Asian Development Bank or ADB has said.




Planning Minister MA Mannan spoke to journalists following a meeting with ADB Country Director in Bangladesh Manmohan Parkash on Thursday.

“The high-speed train can be operated on the existing Dhaka-Chattogram rail tracks,” the minister told journalists citing the ADB country director.

The government plans to reduce the Dhaka-Chattogram train travel time from 8 hours to 2 hours by introducing high-speed train.

Bangladesh Railway has signed an MoU with a consultant firm to do a feasibility study and prepare design for high-speed railway.

“The high-speed service can be provided based on the existing tracks, which I was not aware of. ADB said they already have a survey done on the issue,” the minister said.

ADB has expressed its interest and the government will look into their proposal, he said.

The Manila-based development bank has questioned the speed of project implementation in Bangladesh.

“I told him to let us know at which point they want us to speed up,” Mannan said.

“They want a speedier implementation of projects in the country. The prime minister wants it and so do I.”

The ADB country director called Bangladesh the ‘top most’ debtor, he said.

According to ADB, it gave Bangladesh $5.8 billion in loan after India which received $4.6 billion in credit.

Acting High Commissioner of India in Bangladesh Adarsh Swaika also met the planning minister.

“They too urged us to speed up the implementation of the projects running under the finance of Indian line of credit,” said Mannan.

“The high-speed train can be operated on the existing Dhaka-Chattogram rail tracks,” the minister told journalists citing the ADB country director.

I truly do not trust this statement that a speedier train can run on the existing light-weight railway tracks. A speedy train needs a heavy steel track expressed in kg per meter length. Other points:
1) Better to use high quality steel lines that can take the heat produced in a speedy train.
2) The unit weight (kg/meter) of the track must be heavier than normal. A light weight track is unable to carry the load produced by a speedy train. There is a Standard throughout the developed world.
3) The soil needs to be stabilized with limestone/cement/quarry waste/stone chips for about one-meter depth below the tracks.
4) BD has an old fashioned joint system that makes huge noise when the train runs. So, improved joints must be used.

I am happy to note that the minister guy did not say speedy trains can also be run by the diesel locomotives. Is this news correct? I wonder, why the ministers of GoB has to state such things on behalf of ADB? Why the ADB spokesman himself does not directly say a word?

What are the ADB directors smoking??

DAC-CTG rail link HSR capable?

Am I dreaming or are they?

a) The line needs to be completely cordoned off, and

b) Track needs to be HEAVILY maintained up to precision specs for HSR.

The Shinkansen tracks are maintained at least once a day with a different track crew inspecting the tracks every 50 km or so.

I doubt some of these ADB guys have even seen the tracks (even new tracks) in Bangladesh.

your understanding of the high-speed rail technology is right.
