I remember the journey between BSB to SSM in BSB asn passenger. I was 10 year old and that time this passenger run with coal engine between BSB and mgs. After crossing vyasnagar station there is a huge curve to merge with main line of mgs ald line. Large wheels of coal engine was slips while accelerating the train after halt. And I saw this slipping of wheels of engin through window and never ever forget those feelings.
