When a state govt announces lockdown, it means all services regulated by state govt shut down till the lock down period validity.
But for those services regulated by centre (e.g. railways), it has to make a separate to union govt.
If it agrees then good but if not that central services are controlled to work in tandem.
Here, patnaik govt have made a request...
more... to center to stop all transport services touching the state in that period.
How much curtailment centre makes is to be seen.
Anyways, if the rail service doesn't touches Odisha in any case you need not do anything, will get refund automatically
