The Great Circular Indian Railway Challenge + extras

I am planning to take on the 'Great Circular Indian Railway Challenge', in which I visit the railway stations at the extreme compass points of the nation. These stations, from what I have understood, are Dwarka (West), Udhampur (North), Ledo (East) and Kanyakumari (South). In addition, I want to do a couple of other interesting trips that I have heard a lot about. The first is the 'Dhulghat Spiral' and the other is the Igatpuri ghat section. Information about these is given below for your review.

I am looking out for companions who can go with me on this trip. It is a lot more fun than going alone. I have done the first cut of scheduling this trip and I believe that it will take about 17 days to complete it. Tentative start date is 17th Aug, 2011, returning to Bangalore on 3rd Sept, 2011. The cost for the train tickets alone will run to about Rs.10,000-12,000, especially because there are a couple of Rajdhani Exp legs involved and also because I want to travel at least once by 1st Class AC in Rajdhani Exp (currently the Delhi-Guwahati leg). You will have to add food & lodging expenses to the train ticket costs. Lodging should be very minimal because the train will be our 'lodge' for the most part.

I am also looking for causes that we can advertise or raise money for during this trip. Any ideas from my to-be companions are welcome.
