3-An important station of the Cholistan or Colony Railway Line laid down from Samma Satta, Bahawalpur to Fort Abbas via Yazman.

Tehsil level offices of all important departments i.e. Police, Agriculture, Social Welfare, Education, Food, Forest, sports, irrigation, electricity, telephone and branches of all the national banks are operational here.

[1] Keeping in view to provide an effective infrastructural facility in the form of state controlled communication, a 124 miles project of a railway line from Samma Satta to Bahawal Nagar via Fort Abbas was started in November 1926.

The project of remaining 80 miles from Fort Abbas to Samma Satta with the prominent stations of Mansoora, Quresh, Yazman and Qattal Ammara was completed during the period of next four to five years.

In 1943 Yazman was conferred upon the status of Notified Area Committee (NAC or Sub Tahsil) along with its neighboring cities of Hasilpur, for Abbas and others like Bahawal Nagar, Sadiq Abad, Chishtian and Haroon Abad with a subsequent extension up to 31 March 1947 and a Naib tahsildar was posted who was also ex-officio chairman of the Committee.

The construction work of Yazman City was started through the auction of plots for commercial and residential purpose by the state administration.

The state administration report for the year 1946–47 reflects that “the construction of water courses in Yazman is given due importance.

Yazman is indicating a permanent low profile of development due to poor situation of the communication.” The provision of communication facilities was a major motive in this area.

Apart from the railway line (discarded after only five years), lorry service was started between Bahawalpur to Fort Abbas and Yazman on the non-metaled road which continued up to the merger of the state in Pakistan till 1955.

Some parts of Cholistan are open plain spaces, locally called “Dahars” where soil is alluvial and suitable for cultivation.

The other parts consist of sand dunes, called “Tibas” rising at some places up to 100 meters with vegetation peculiar to sandy tracts.

There are more than 400 archaeological sites that were once populated as per survey report of Dr. Rafique Mughal which was carried out in the winter of 1978 and published in an international magazine.

With the passage of time, its feeder channels changed route thus the vast tract of irrigated land converted into desert now called Cholistan.

Their sub-clans include Laars, Chatta, Thathyala,Cheema, Warraich, Rehan, Ghuman, Sidhu, Uppal, Janjua, Rathore, Bhatti, Leghari, Lashari, and Dashti.

The most visited ancient site is Fort Derawar which is situated in the middle and on the interlinked old communication network of the Great Desert of Cholistan.

Another Raja Diwa Sing sought permission from his maternal uncle Sardar Jajja Sing to construct the fort at a bank of Hakra in Cholistan which was granted and its erection started in 837 A.D. Due to unknown reasons, Raja Jajja ordered to suspend the process of construction.

In 1825, Nawab Sadiq Muhammad Khan III built a mosque in front of it on the true model of Jamia Masjid Dheli.
