Central Railway General Manager Ram Karan Yadav, along with his team, on Friday took to hike the Khandala Ghat hills to conduct a comprehensive pre-monsoon inspection of the Karjat-Lonavala section on the Pune-Mumbai route. This segment, comprising 52 tunnels, towering hills up to 250 meters, and sharp curves with steep gradients, is vital to the Mumbai division's operations.

These mountain stretches have the steepest gradient in the country of 1:37 which means there is a 1-metre rise for every 37 metres.
