This reduction seems to be affected also by staff shortage.
I think that train drivers who tested positive but have no symptom should work, if they wear masks and their hands are sanitized while working. When we consider that crews rarely talk with passengers and reduction of train may cause crowded trains, it would be better to let them work.
