i have 1980 time table where we could see neelanchal exp took only 5.30 minute to reach Kanpur from New Delhi , few years back only Rajdhani was taking such time or below than ,Kudos to Railway ,they have taken so much initiative in last couple of years and speed increased otherwise railways stuck after independence unless BJP started ruling. Other example Himgiri Exp departed 5.45 from howrah and reached Patna 12.18 , only 6.30 minutes and still Rajdhani is taking much time than 1980
