If you are trying a ticket in this train and not able to get. Try following option. Get a ticket in Avadh Express, which runs just before it and generally TTE are able to accomodate you in Avadh by charging differential fare between UR and SL. Get down at Dahod. At Dahod, on the same platform on which you get down from Avadh, after few minutes comes 22901. So you can have nice sleep in avadh and then spend rest of day journey in 22901. I have tried it myself once.
you have told about a chain which has just 25 mins of buffer...
If you see route, both trains run back to back from BDTS till Dahod. I have always observed that no overtaking happens before Ratlam. Avadh first reaches Ratlam followed by 22901. At times both meet at Ratlam Platform 5 and Platform 6 and then moves for their respective destinations. Avadh towards Nagda and 22901 towards Mandsaur.
its a chain tip , and it should be discussed in chain category ,,
also , we have to see ticket avl in avadh from bdts to dahod and ticet avl in 22901 from dahod to udz ...
buffer time less is also a big factor
When I travelled recently in 22901, we reached Ratlam and 19037 arrived on the adjacent platform and our train left from Ratlam. Also, at Dahod and in between, I did not see 22901 overtaking 19037
