Sengundram

Sengundram, known in English as Red Hills, is a suburb in the northwestern part of Chennai, Tamil Nadu, India in Thiruvallur District. The name was derived from the red hills (Semman Kuviyal) that was formerly present in the area.

History
The first railway proposals for India were made in Madras in 1832. The country's first transport train, Red Hill Railway (built by Arthur Cotton to transport granite for road-building), ran from Red Hills to the Chintadripet bridge in Madras in 1836-1837. A town named Sholavaram has a unused airstrip build by British for World War II. It was originally operated by the Royal Air Force as an airbase during World War II. After the war, it was abandoned until the airstrip was turned into a venue for drag racing. Most notably, the Malayalam actor Jayan was killed in a helicopter accident here during the shooting of his film Kolilakkam on 16 November 1980.

After the Madras Motor Sports Club was formed in mid-1950s, Sholavaram was selected to conduct its racing events. According to some estimates, entries across all the various categories of motorcycles and cars together numbered over 800. The state government would ply buses ferrying fans, who travelled from all over India, to and from the track. There was even a thriving black market for forged tickets. Participants included Vijay Mallya's Formula One Ensign or Chandhok's Formula 2 Chevron B42. Since then racing events took place every year and continued till late 1980s until the Madras Motor Sports Club built a new track at Irungattukottai, Sriperumbudur, Chennai.

The Indian Army later recovered the lands, which had been illegally occupied by local residents. The military used the area and the remaining airstrip as a surveillance base. There were also plans to use the airport as a secondary landing location for commercial aircraft.

In 2020 the airstrip was taken over by the Government of India, with plans to construct a new airport under the UDAN scheme.
