S-6 has 36 Seats allotted to Moradabad from NDLS and 6 Seats in 3 AC. Not sure about 2-AC. Since I work Mon-Fri, This is the best train for me to return to Mbd from Noida.. It takes me 40 mins to reach Gzb station from my office. This train is always on time and reaches Mbd before or right time. And Since S-6 has quota, I always get my preffered seat.
