Then, one fine day, the train came and Gedu turned into a brand new town overnight. Thanks to the 1,020 MW Tala Hydroelectric Project Authority (THPA), Gedu today is one of Bhutan's fastest growing towns.
The executive engineer of the infrastructure, Mr V P Arora, said that what he saw in 1997 and 1998 and what he sees today are vastly different.
"Before there was no telephones or STD facilities, we had to go to Phuentsholing to call our families," he said. "Before Gedu used to be foggy almost all the time and now fogs hardly appear. The climate has become much warmer."
Today, the town is bustling with life - the project generated both business opportunities and employment. About 90 percent of the buildings that have come up in the last four years were built by the project authorities, some for offices and some as homes for its staff. For residence alone, the THPA has constructed 843 units of apartments. About Nu 897.117 million was spent on the buildings (including the high school at Gedu) constructed in and around Gedu on a total plinth area of 132,505 metre square.
The cost of the construction of the buildings and the sports infrastructure amounted to about Nu 50 million.
"We have carried out the constructions keeping in mind the traditional architecture and as well as the environment," said Mr Arora. "Some areas of forest had to be cleared for constructions but we have planted many trees, as many as we have cleared."
A total of 122 kilometres of roads was constructed at a cost of about Nu 1222 million, and 15 bridges at Nu 104.5 million. Mr Arora said that the THPA will also widen and improve the highway from Gedu to Phuentsholing at certain places.
Gedu is also supplied with free treated and filtered water from the water treatment plant built at the cost of Nu 30 million. The plant, with a storage capacity of 707,600 litres, can supply to a population of about 5,500.
The construction of a sewerage treatment plant, begun with a cost estimate of about Nu six million, is scheduled for completion by the end of this year.
"In 1998 when I came here Gedu was a small and sleepy place and the shops used to open only at about 9:30 am. Today it opens at 6:30 am," said Mr Vatsal Chopra, the superintending engineer of powerhouse. "Now we also have medical shops."
About 30 to 40 calls are made daily. Gedu today has four booths from none before.
In the beginning of 1999, Gedu had only about three telephone subscribers.
In 2002 it had about 250 while Padechu has 20, Sinchekha 50, and the Tala village about 60.
resident said that he knew of a businessperson who had nothing three years
ago but now had a fleet of trucks.
According to the Royal Bhutan Police at the Rinchending checkpoint, about 500 vehicles (including trucks and light vehicles) associated with the THPA cross the checkpoint daily.
However, some believe that Gedu could face a future similar to Tshimalakha, which has today become a "ghost town". The Chukha Hydroelectric Project created Tshimalakha but when the project was completed, the small town was left high and dry.
Mr Arora said that when any project starts there will be business and where there is business entrepreneurs will be attracted. "The government has to come out with ideas to use the created infrastructure judiciously," he added.
Pema Dorji of Dzorig Gongphel Construction said that Gedu's fate would be different. It was a transit town, located on the busiest highway unlike Tshimalakha, which is situated off the highway.
"One has to take a detour to go to Tshimalakha where the road ends," he said. "And there are no places to go to from Tshimalakha. Gedu will remain as it is, at least if it doesn't grow."
