The line was opened in 1928 by the Great Indian Peninsular Railway under the Bombay Improvement Trust which called for "the opening up of a Railway line running West to South-east and linking up the Andheri and Kurla stations to render available for building purposes vast tracts of land sufficiently close to the city.
"[1][2] Hence, the line linked Andheri in the north with the village of Trombay in the east.
During weekends, the line was frequented by picnickers who used to travel to Trombay to buy toddy or palm liquor.
From here the line headed West along the present C. S. T. Road towards Santacruz with halts at Kolovery and Kole-Kalyan and finally turned north towards Andheri with halts at Sahar and Chakala stations.
The line operated eight steam engines[4] built in Britain by W. G. Bagnall in 1921 and delivered new to the Salsette Trombay Railway.
