Global Pass train reservation help

Eurail passes allow travel on the majority of trains in Europe but there are some operators that are excluded, the 13.42 is one of these.

While most trains are free to use without any additional payment some trains have compulsory reservations with a fee for the reservation. High speed trains in Spain, France and Italy are reservation compulsory with fees starting from €10 per seat.

If you want to compare to the standard ticket cost without a Eurail pass you can go to the operator websites such as https://www.renfe.com/es/en 

The Eurail site and app only shows passholder reservation prices.

A good place to compare prices with and without a pass is Rail Europe. I would recommend paying in Euros (they charge a hefty conversion fee for other currencies). You can specify a Eurail pass in the search box.

Here are prices for 1 person. The cash price (without a pass) is €88 - €154. The cost of a seat reservation, with the pass, is €10 - €13.

(There’s a sight quirk with Rail Europe. It will show you second class reservations if they're cheaper, so click on the ‘Upgrade’ button to make sure you're in first class for a few € more)
