The Green Line (ur|{{Nastaliq|سبز ایکسپریس) is an express train operated daily by Pakistan Railways between Karachi and Islamabad.[1] It is the flagship rail of the organization and has the highest passage priority.[2] The train takes approximately 21 hours to cover a published distance of 1521km (945miles), traveling along a stretch of the Karachi–Peshawar Railway Line. It was inaugurated by Mian Muhammad Nawaz Sharif on 15 May 2015 at Islamabad railway station.[3]
The Green Line is among the trains operating in the luxurious category. It features an AC Parlor Class that resembles the look of a luxury bus. It has two parlor cars, five Business coaches, and six AC Standard coaches. It also has four to five economy-class coaches.
In the wake of the 2022 Pakistan Floods, the train's operations remained suspended since 27 August 2022.[4] With the floodwater receding and rehabilitation of effected train tracks completing, Pakistan Railway announced to resume Green Line's operations in December 2022.[5]
On 28 November 2022, 46 high-speed coaches were delivered to Pakistan Railways by the China Railway Construction Corporation as per the agreement signed in 2021. These modern coaches were employed first in the Green Line.[6]
Green Line Express was re-inaugurated by Prime Minister of Pakistan Shehbaz Sharif on 27 January 2023 [7]
