article imagePassengers face late arrivals caused by low gas pressure Special

By Ernest Dempsey     Jan 3, 2011 in Travel
Kohat - With natural gas-run vehicles more commonly used for traveling between cities, passengers in Pakistan are getting late in arriving at their destinations as gas pressure remains low in winter.
With the rise in the intensity of cold weather, traveling in CNG-run transport is subject to bothersome waiting periods midway due to low gas pressure at gas stations. This is the case with CNG filling stations serving inside big cities as well as those at the junction of highways leading between cities and smaller towns.
An instance of this inconvenience took place this morning as I traveled from my hometown Hangu back to Peshawar. At Kohat city, some 40 kilometers east of Hangu, just close to the road’s turn that leads to Peshawar, our vehicle stopped at a CNG station to refill the large gas cylinder that lay under the seat ahead of me. While a few accidents of cylinder blasts inside taxis/cars during filling have occurred before, it is generally assumed safe to refill a CNG fuel cylinder in a vehicle with the passengers still seated inside.
The HiAce I was traveling in stopped and waited for at least 20 minutes at the gas station amidst a dozen other vehicles, including Suzuki vehicles and cars, in order to get its CNG cylinder refilled. The reason explained was not new – low gas pressure.
Finally, as we moved on and reached Peshawar, I asked a cab driver whether low gas pressure was the problem now in the city as cold weather had grown more intense. He negated. But as I went out to get my lunch along the main University Road, the line of ten vehicles waiting their turn to get their CNG fuel tanks refilled showed that things were pretty same here as in Kohat. Later, the low gas pressure also showed in a small gas heater, which lit dimly till late in the evening.
As larger public transport vehicles are now turning their engines from diesel to CNG, arriving at destination in winter is generally getting delayed for many passengers, whether within cities or between them. Vehicle owners, however, prefer CNG fueling systems because they are comparatively inexpensive than diesel or petrol.
