"All aboard for Hogwarts": Many readers of this blog will soon be sending sons and daughters back to school for the semester. Your child may or may not be headed to Hogwarts, but Hogwarts is just one of the many destinations serviced by Scotrail.When I talk to people about a trip to Ireland and the rest of the British Isles, travel by rail is seldom a topic of conversation. It should be, especially for a couple. For a larger group, hiring a driver often makes sense economically. Americans are more comfortable on the road but in the British Isles, rail is often the way to go.
