yes,it will be comfortable. no worries, ive travelled a lot from bsp raipur in betwa slot trains and yes if not on time it reaches raipur by 1pm. it actully depends upon different trains. if you look closely at bsp dep. thats a very busy time. 12102 departs at 9:50 followed by 12252/17481. so betwa dont get much preference throughout. if possible try to catch 17481/12252 slot to get more time at raipur.although im sure it will reach by 1pm.
on rare days ive seen betwa arriving on bsp at 8:40am{1 hr before},so yes there are enough slack given.
17481...
more... departs from pf7 in bsp station,and your betwa might arrive at pf8,so its easy for you to shift trains.
