My youngest son John uses the train regularly, mainly to come home from school when he has attended after school activities, but also to go to and from Hereford to meet up with his friends. He has never had a problem with the trains until yesterday when he managed to get on the wrong train. It was a simple mistake. An earlier train was late and arrived at the time John expected his train to arrive. He didn’t hear any announcements and didn’t look at the monitor on the platform.
