Regarding 2A class.
The coaches are EXTREMELY neat and clean with Best maintenance. I have personally traveled many a times in 2A coaches from Ajmer-Delhi and Vice-versa. Always its very Pin drop silence inside the 2A coach. While travelling towards Delhi , if you have de-boarding at Delhi (Coach Attendant checks out the charts properly for people alighting at Delhi) , then after Gurgaon , he will come and wake you up politely so that you don't miss Delhi which comes at a very heavily slacked , dark and early morning time.
