Rail Europe (formerly Loco2)

Rail Europe (which used to be known as Loco2) is a great app for buying train tickets in Europe. I have used this app to travel from Paris to Barcelona, from Barcelona to Valencia, from London to Bristol, from Milan to Venice, from Venice to Florence, to Andalusian cities like Malaga, Granada, and Seville, and to other English cities like Liverpool, Manchester, Leicester, and Nottingham. Here are my thoughts on the app after using it:

Environmentally friendly-
The app's old name, Loco2, refers to its environmental friendliness. Trains use less carbon dioxide than other methods of travel, so the Loco2 name is a play on words for both "locomotive" and "low CO2." Although it has changed names, it still has kept its environmental conscious mission.

Easy to use-
The app is very easy to use. First, you pick your starting point and you destination, which can be general or specific, such as "any station in London" or "Victoria Station." Then you can choose the date and time and click search, and it will give you a variety of different options.

Multiple transport methods-
Although the main focus of Rail Europe is obviously train travel, it will also search some bus options. This makes it a great place to start regardless of the method of travel you are planning on taking. I used the bus option when I was traveling in Andalusia, as there are not great direct train routes there.

Low prices-
Rail Europe uses something called "Pricehack" for many train routes that helps to reduce the cost of train tickets. When you have to connect trains and purchase directly through the train company, sometimes you will be charged more. However, with Rail Europe they will combine the cheapest possible fares, resulting in a cheaper price. This has helped me get cheaper tickets multiple times.

Bottom line-
Whether you use the website or the app, Rail Europe is a great resource to use when traveling in Europe. It is the first place I check when looking for train or bus travel. If I need to get from city to city in Europe, the only site or I use as much as Rail Europe is Google Flights. I highly recommend checking out Rail Europe if you are traveling in Europe.
