The 6012 Chennai Dadar express emerges from Tunnel 26 and moves to plunge into the Tunnel 25. The tunnel 25C is inside the hill on the right. The service shaft for the tunnel 25C is located on the other side of the 3rd coach. Although this is a very hot and dry season, note the perennial waterfall caused by the water leaking from the Tata pipelines. This serves as a water source for the villages in the valley.
