the speed of golden temple till mathura is 73kmh/hr which is very good. but what happens after mathura the speed is almost down by 30kmph. this is one of the oldest and one of the best train in india. it almost 14hrs to cover 650km from mtj to asr while compare to bct to mtj this train covers1300km in 18hrs why there is so big difference. i think speed of this train should be around 65-70kmph from mtj to asr.
