It will be better of railways start a new train between kathgodam and Pune-SF- via Panvel. There is big demand for a diretc train for Nainital. Since Nainital is not on railway, nearest station is kathgodam. The route may be Kathgodam, RamNagar, Bareilly-Budaun_Kasganj-Mathura-Kota-Baroda-Surat- Vasai Road, Panvel-karjat-Pune.
