Falna have Waiting Room Facility. I used it in MAY'2013. U have to request station master to open it. Retiring Room are not available but lots of Lodges are available around station.
one Jain Temple is situated just 2 min walk from station with staying facility with all amenities i.e. Food, ac or non ac rooms etc with very nicely maintained. This temple is called GOLDEN TEMPLE and even water in taps comes in Golden Colour.
