well i said what i said given facts with train name and stations based on my own experience and let someone give me say i m wrong who has actually had a ride during that time.
it started 4:00pm from karachi and reached rohri/sukkur 9:30 or 9:45 max then it went up to 10:15 then 11:15 and last one i had three weeks back was 12:20.
travel had one stop over around 10min , with 15 mins slow ride due to hyderabad city limits, and also almost 20-30km slow ride for karachi city limits.
although its not the topic which one is faster but i am surprised at your response as if it was your disbelief that can happen in pakistan.
well train i referred to had top speed of 140KM/H then (almost 3-4 years ago) i guess rarely it touched that benchmark that is when PR was overhauled tracks were repaired and now same train is pathetic same distances 8-9 hours with inhouse condition much better than average indian trains but pathetic than how it was.
