India has a whole hospital running on track, "The lifeline Express", having a hospital in a train isn't a new thing for india and indian railways. Second, It doesn't require rocket science to install emergency equipments like ventilator, oximeter, infusion pump, Apnea monitor which would be required in treating COVID-19 patients in a coach. EOG or DG sets can be used to power the coaches. It's an innovative Idea and Central Government should think about this. If, God forbid, community transmission starts in india then it would get ugly bcoz we don't have hospitals to accomodate thousands and millions of people.
