- 27 -(1) The narrow-gauge Delta Railway, with a total length of 952 kilometers. (2) Lower Egypt Railway (109 kilometers). (3) Fayoum Railway (169 kilometers). Balaghal said that the output of these companies in 1911 was good, with net revenues reaching £1,170,000, compared to £1,110,000 in 1910. Their capital value is about £2,400,000. The increase is evident in the number of passengers and the volume of goods. Furthermore, the narrow-gauge Delta Railway shares 40 kilometers of the broad-gauge lines between Cairo and Helwan. Since its inception in 1905, it has incurred about £80,000 for renewing the line and starting with a lesser line. Although the revenues of this line have increased, it has not yielded the expected results due to the significant expenses incurred to make the railway operational. Substantial expenses will still be required before it truly meets expectations. - 11 - Petroleum Extraction In 1911, researchers continued their search for petroleum oil on the Red Sea coasts. Although they did not find new sources or drill new wells, progress in these sources was significant, leading to profits and many matters related to exploration, prospecting, and future financial arrangements. The only sources yielding oil for extraction are located in the area where the Anglo-Egyptian Oilfields company established a complete system for storing crude oil and shipping it directly onto tankers. This company was formed in the past eleven months and represents the share of the Anglo-Persian Oil Company and the share of the Anglo-Siam Petroleum Company. The drilling of exploratory wells continued in other directions, yielding results from testing that offer hope for opening new oil sources in those areas.
