More than speedup this train needs more lucrative originating station either PRNC or JBN or KIR.
SHC alone cannot fill 2 daily Intercities (Rajyarani, IC) & 1daily overnight train for Patna. Non COVID time me bhi this used to run with many vacant berths regularly.
Abhi wala time is ok. 11 pm departure from SHC & 5-6 AM arrival at PPTA is ok. Isse fast hua to passengers ki neend poori nahi ho paygi 😂
