Visit the Web site of one of the general booking agencies that services all the rail networks in the United Kingdom, such as Britain Express. You will be able to book your travel with one transaction, even though several different rail carriers might be involved. You can also book train travel from Cambridge to Edinburgh by calling Rail Europe at (888) 382-RAIL or by visiting the link below.
Choose to simplify the number of stops you make by using London as your center point. This may add an hour to the time you spend on the train, but it may reduce the time you spend in the various stations.
Ask a travel agent to assist you with booking the most efficient routes if you get too confused by all of the possibilities.
Purchase an unlimited rail pass to travel through the various cities of the United Kingdom at your own leisure.
Book your tickets one leg at a time from each station. This may not be the cheapest method of travel, but it certainly offers you the chance to improvise your routes as you go.
Stick with second-class travel to keep the costs low and the energy level high as you switch from train to train.
Spend the money that you save on your second-class carriage by choosing flexible tickets whenever possible. A restricted ticket, which is non-refundable and non-exchangeable, might be wasted if you miss a connection at one of the stations due to delays.
Use the Kings Cross Station exclusively as your base if you choose to switch trains in London. The Cambridge train will take you to Kings Cross, and trains to Edinburgh are available in almost every London rail station.
