Couldn't understand the rationale in providing 3 staff section for 500km for 6.5hrs. Cant the staff of KGP Khurda go to Puri and return from Puri? Is it the same for other express trains to Puri? It should be manned by one staff section from HWH to Puri given rest for next duty hours and another section staff should do the return leg.who arrive in morning after taking rest.
