The original Mahim station belonged to the GIP Railway (today's Central Railway), and the company began services to the station all the way back in 1853, when it started India's first passenger train service from Bori Bunder (in Bombay) to Tannah (now, Thane).

The original station was located near the Mandvi (Custom House) near where the Mahim Causeway starts.

The Mahim route diverged from the main line only near Sion,[3] with the only intermediate station being Byculla, as referring to a timetable published in a Bombay Times (today's Times of India) report published on 8 April 1853.

It was speculated in a report, that the railways would transform Mahim from a simple fishing village, to a port of importance.

Further, to suffice the demand for better local service, tracks between Parel North Cabin and Mahim were quadrupled temporarily, opening for passenger traffic in May 1922.
