# Sampige line

The Sampige line is a planned Bengaluru Suburban rail line running from KSR Bengaluru to Devanahalli and the Kempegowda International Airport. The 45 km (28 mi) long broad-gauge line was approved in 2019 and in 2024 was in the tendering process. The line which is also referred as 'corridor-1' is planned to be constructed in two phases C1A and C1B respectively.
The C1A section runs from KSR Bengaluru to Yelahanka Junction railway station. While the C1B section starts from Yelahanka Junction and ends in Devanhalli town in the north. C1B also includes a 5.5 km (3.4 mi) branch line towards the Airport. The line is named after the regional flower Sampige (Magnolia champaca) in Kannada.

## History

While the earliest proposals lacked a suburban railway line linking Bengaluru to Devanahalli, it was only after the inaguration of a new international airport near the northern town of Devanahalli that a line was considered within the proposal. The 'Call To Action' report in 2010, had the proposal of the line Yeshawanthapura Junction to Chikkaballapura via Yelahanka Junction and Devanahalli. In the next proposal by RITES in 2012, consisted a line from Yelahanka Junction to Doddaballapura while passing 6 km (3.7 mi) from the Airport. A branch line connecting the same was first mooted under this proposal Later in 2019. RITES submitted a revised project report that included the latest plans for the Devanhalli and Airport line.
On 7 October 2020, government of India approved the four corridors of Bengaluru suburban rail project including the KSR Bengaluru – Devanahalli line and its Airport branch. The line was then named after the regional flower's Kannada name Sampige. While the construction works commenced on Mallige (line 2) and Kanaka (line 4), Sampige line had been pushed below the priority list according to the Karnataka's minister of Railway, V Somanna. As per the minister, Sampige and Parijaata lines presented their own challenges involving technical and administrative work in which, the government's special purpose body K-RIDE lacked. In 2024, a revised alignment plan was submitted to South Western Railway and the approval was awaited. The line was divided into two packages: Package 1A (KSR Bengaluru to Yelahanka, 17.63 km (10.95 mi)) and Package 1B (Yelahanka to Devanahalli, 23 km (14 mi).
