Work on the construction of circular train, linking Peshawar with Charsadda, Mardan and Nowshera, will begin by December this year.
A Spokesman of the provincial government told Radio Pakistan's Peshawar Correspondent Falak Niaz that the project will be completed at a cost of one point six billion dollar in three years.
The train will have a speed of two hundred and twenty kilometers per hour.
In the next phase, the train service will be extended to Swabi and other areas of the province.
