Genève / Geneva to Luzern / Lucerne by train

SBB is the main national rail operator in Switzerland, but tickets for journeys by the other significant operators including BLS and SOB can be be booked on the SBB website.

SBB also sells tickets for journeys to many destinations which involve a combination of SBB trains and services provided by the many independent operators who serve the Alpine resort towns.
However, if you will be making a long-distance return day trip, look out for he possibility of SaverDay passes being cheaper than tickets.

Though if you download the SBB app, booking tickets on SBB's mobile services can be simper than using the website.
Also watch out for the fact that booking international tickets can be comparatively quirky.

Omio is an online ticket agency which offers tickets for rail journeys in France, Germany, Great Britain, Italy and Spain.

The three key advantages of using Omio are

• it offers prices in multiple currencies
• it usually offers price comparison with other modes of travel including flights and buses
• when visiting Europe, you can book journeys in multiple countries in one transaction.

The disadvantage of booking with Omio is that it often adds a booking fee to the final price; therefore when it does so without offering a price advantage, SMTJ doesn't tend to offer Omio as a booking option.

Happy Rail is a Netherlands rail ticket agency which sells tickets for both national and international journeys within a range of countries including Belgium France, Germany, Sweden, Switzerland.

HappyRail doesn't charge booking fees in the conventional sense, but if you're not Dutch you can expect to pay additional transaction fees, which will be added to the total cost.

Other forms of payment include Visa debit cards will incur a fee.
