रेलफैनों की तो बात ही कुछ और है

There is a guideline that passengers travelling from Mahashtra need to produce negative RT-PCR report while entering Karnataka. However, if a train is travelling through multiple states, how someone in Karnataka will determine whether the arriving passenger needs RT-PCR or not? e.g. train can start from Delhi and pass through other states incl Maharashtra and then enter Karnataka. So do all passengers of that train need RT-PCR since the train travels through Maharashtra or only the ones whose journey is starting from Maharashtra?
