People travelling between Lucknow Lalitpur and specifically between Kanpur Jhansi please prefer travelling by bus since the trains are being diverted via Kanpur-Etawah-Gwalior-Jhansi (instead of Kanpur-Orai-Jhansi) and are late by 6-8 hrs.
My relatives UP train was late by 6 hrs. and DOWN train by a whopping 10 hrs.
You will regret this journey if you are travelling in sleeper classes.
