As a result bringing a pet to Britain with you is not really worth it unless you will be staying for a long time. There are lots of options to choose from so here is a brief guide to some of them. Trains The UK rail system has recently been privatised so now there are a variety of rail companies operating. As a result, if you are going for a long journey across the country, you may find that you not only have to change trains as you travel, but rail companies as well. However, you should be able to buy all your tickets from any train station or from larger travel agents so you should not have to worry about searching out the relevant company's office.
Rail travel can be expensive, but there are various reduced fare options available.
Make sure that when you book your ticket you ask for the cheapest option and bear in mind that if you book 7 days in advance you can make some substantial savings. There are numerous ticket types available with different rules and restrictions for each. So the best advice is to ask at the nearest train station. You need to buy this pass before you enter the UK or Europe so ask your travel agent for advice and costs. Once you are in the UK, some other passes are available which give reduced fares - ask for details at any rail station.
