The two lines of the Great India Peninsula system approach one another from Allahābād and from Madras at an angle. They are carried separately down the steep mountain edge of the Deccan Plateau by two passes, the Thalghāt and the Borghāt, which have put the skill of engineers to the test. The junction is in the narrow coastal plain at the foot of the mountains. Thence the rails pass by a bridge over a sea strait into Salsette Island, and by a second bridge over a second strait into Bombay Island.
