i think Your Correct . Mainly People Boarding at SC prefer SBC rajadani than to SC rajadani. Because of old Coaches . It is easy to get confirmed berth in SC rajadani except during summer if we book 2 weeks before our journey . The SC rajadani must be given LHB coaches and hand the Train and coach maintainence to SCR. because SCR has one Single prestigous Train like rajadani and Shatabdhi
