A mere 5 min stop per station (elderly passengers cannot be hurried) will result in a  total loss of 5 min x 30 stations or 2.5 hours of train journey time!

Cool, the person travelling from first station to last station will now save a heck lot of time. , But they all need to reshuffle a lot in the train.
