only train that can be diverted is the indore udaipur express via fatehabad ratlam reason being in MG era this connectivity was via Fatehabad only and for ujjain passengers there used to be connecting train for ujjain from fatehabad.
The other thing that can be done is run indb bhind intercity 3 days via ftd ujjain and 3 days via dewas maksi as a result of which reversal will be avoided and some load will be taken off from dewas ujjain which will get doubled in 2nd phase of indore ujjain doubling. First phase they are taking indore dewas which has more traffic then dewas ujjain
