thats the 20955/56 Mahuva superfast express.
Between Ahmedabad and Bhavnagar there are buses available and now 2 trains are also available for a distance of 270 kms. Many people prefer buses and some may go in trains to Bhavnagar as they are recently started.
Other places like Okha, Porbandar, Somnath are farther than Bhavnagar from ADI,BRC, ST as Sabarmati Botad route is one of the shortest route to reach Ahmedabad from Bhavnagar

more... people prefer bus over trains as it drops them at their doorstep (village). In fact in India people in rural areas find bus and tempo type ricksha more convenient than trains as they don't halt at every single station or every village hasn't a railway connectivity too.
Agreed that the places like Palitana Okha Porbandar, Somnath, Bhuj- other places of Kutch require massive rail connectivity to BRC ST but this possible by having more rakes, smaller terminal stations and developing alternative stations in major cities of ADI- VAPI belt to avoid congestion there.
