The metro rail methods have confirmed to be most effective by way of vitality consumption, area occupancy and variety of passengers transported the world over. In addition to, there contain very low floor area occupation, two meters width just for elevated rail and might guarantee problem free quicker journey.
It’s pertinent to say that metro trains have revolutionised mode of transportation in every single place on the planet. These are working efficiently within the US, France, China, Japan, UAE, India and so forth., and now it’s Pakistan’s flip to have a contemporary public transport system in a bid to minimise visitors woes and usher in a brand new period of best-commuting services to the individuals of Lahore.

Orange Line, an automatic fast mass transit system, is the primary metro prepare of Pakistan because the Karachi Round Railway which had closed its operations throughout 1999.
The road spans over 27.1 km size with 25.four km elevated and 1.72 km underground parts. The road is served by 26 stations and is designed to deal with 250,000 passengers every day.
Exim Financial institution China offered a smooth mortgage of $1.55 billion for the venture.
As a way to guarantee completion of the venture in accordance with the excessive requirements and high quality, Punjab Mass Transit Authority, Authorities of the Punjab appointed NESPAK and China Railway Engineering Consulting Group Co. (CEC) as a three way partnership for offering consultancy companies for execution of the venture.
As per settlement, NESPAK was liable for bid analysis, detailed design and development supervision of civil works, whereas, CEC was primarily liable for design session for civil works and evaluation and supervision of electromechanical works.
CR-NORINCO was the three way partnership of China Railway Company and China North Business Company for EPC contractor for electrical and mechanical works. NESPAK carried out design of civil works whereas considering the native pure, cultural, non secular, environmental and different elements. The design not solely meets the purposeful necessities of a contemporary city rail, but additionally supplies a contemporary, protected, snug and handy technique of transport for passengers.
Development work on the venture began in October 2015. Habib Development Providers was awarded the Section-1 of the civil works from Chauburji to Deira Gujran for Rs 21.49 billion (US$ 130 million). ZKB Engineers and Contractors was awarded Section-2 for civil works between Chauburji and Ali City for a value of Rs 11.39 billion.
CRRC Zhuzhou Locomotive rolled out the primary batch of 27 trains on Might 16, 2017. Testing and trial runs started in March 2018. On October 25, 2020, Orange Line Practice was inaugurated by Punjab Chief Minister Sardar Usman Buzdar. Out of the 26 stations enroute, Anarkali and Central stations are underground, whereas the remaining 24 stations are elevated. Elevated stations have a width of 22.50 meters, whereas Anarkali station is 16 meters vast, and central station is 49.50 meters vast. Elevated stations are all 102 meters lengthy, whereas Anarkali and central stations are 121.50 and 161.50 meters lengthy, respectively. Stations characteristic automated doorways between platforms and trains. Public areas of the station are air-conditioned. The Orange Line’s tracks are as per Chinese language Nationwide Requirements and make use of jointless observe circuits.
Mainline observe rail is 60 kg/m whereas rail in depot and stabling yard observe is 50 kg/m. Observe is laid on monolithic concrete observe mattress, with crossovers positioned between each 2 to three stations.
Elastic fasteners have been used between tracks. The utmost pace of the trains is 80 km/h (50 mph). Complete journey time from one finish of the system to the opposite is estimated to be 45 minutes.

To cut back the influence on environmental panorama, stations and bridges are supported by a single pier.
Elevated stations with clear curved glass curtain partitions undertake a mix of straight and curved line, which is straightforward and stylish in appears to be like. The elevated stations are designed using building-bridge built-in structural system with single column piers and lengthy cantilever beams. They scale back the land acquisition necessities.
For underground part, new cowl excavation methodology has been adopted which resulted in about 30% saving in the price of civil works.
Islamic architectural components in Anarkali station rework the station constructing right into a landmark within the metropolis centre. Elevated bridge (viaduct) for the Orange Line boasts a novel and engaging look. The bridge has a singular form which incorporates U-shaped girders having S-shape curved configuration resting over gem formed pier cap on a stable cylindrical pier.
This form has been adopted for the primary time within the nation for development of any bridge. The bridge configuration reduces the structural top, enhances the visible clearness, successfully minimizes noise air pollution and on the identical time it enhances the city skyline. Every pier is supported on a gaggle of typically 9 to 12 drilled shafts of 1200 mm dia and 16 to 25 m size.
The quantity and size of piles enhance at station areas.
The shafts had been drilled with trendy rigs of straight rotary and rotary bucket auger varieties.
A sequence of final and proof load checks has additionally been carried out on shafts for the design verification as properly to regulate the development high quality.
In addition to, each single shaft was additionally examined by Sonic Integrity Tester to make sure top quality of substructure.
The completion of this distinctive venture has added one other feather to NESPAK’s cap.
It’s the first of its sort venture within the historical past of Pakistan. Orange Line won’t solely assist ease congested streets but additionally provide profitable enterprise alternatives.
Like different developed components of the world, frequent residents in Lahore additionally deserve clear, quiet and air-conditioned public transport system. The electrical trains will scale back visitors congestion, air and noise air pollution within the neighborhood of probably the most distinguished monuments.The route additionally affords easy accessibility to guests to heritage websites of Shalimar Gardens, which might assist entice vacationers from throughout the nation and overseas. “The train is a small world moving through a larger world.” …….
