Explanation:

Perambur is served by three railway stations: Perambur, Perambur Carriage Works and Perambur Loco Works. It is one of the earliest British settlements in Chennai, mainly because of the railway establishments during the 1850s. Perambur is noted for the largest presence of Anglo-Indians in Chennai (and arguably in South India) because of the erstwhile British settlements in and around Perambur, during the construction and running of the Integral Coach Factory (ICF[2]). The ICF is located only in Perambur and Kolkata in India. Perambur houses many Malayalis who work for the railways. St. Joseph's Syro-Malabar church is a Catholic church in Perambur which serves the Malayalee Catholics of north Chennai.
