The Royal Train has two locomotives, and several carriages, and in fact is longer than some passenger trains!

And why not! If Her Majesty has the longest motorcar ever built, then why not also have a great big train to travel around Her Kingdom!

It also has two drivers, one of whom can be seen here. The other one was present, but not visible in this picture.

This is the information panel located just to the right of the driver's door, for anyone interested in these things!
