If its still SCR the train can leave at same day around 15:55 PM after arriving at 12 PM like I mentioned and then cover CBE till 23:55 PM and arrive SC at 19:00 PM night and go for PM from night till next day morning around 07:00 AM
If its SR , the train best to leave at morning but might require extra rake. If not make it two night , one day train to reach CHZ at 04:30 AM and leave as return train at 08:00 AM
