How to take the a rail journey from London to Luxembourg

The variations in journey time partially depend on the connecting time between the trains at Bruxelles Midi/Zuid station.
The quicker journey times are indicative of a transfer time between trains of around 20 minutes.

If you miss the connection in Bruxelles due to a delay on the Eurostar, your tickets will be valid on the next train on to Luxembourg; because seats cannot be reserved on the Bruxelles - Luxembourg trains.
There is 1 x train per hour daily between Bruxelles/Brussels and Luxembourg.

More information is available on our changing trains at Bruxelles-Midi station guide.

At St Pancras:

Eurostar is currently suggesting that Standard Class And Standard Premier ticket holders should be at the Eurostar departure area in St Pancras International 90 mins before departure; and that Business Premier ticket holders should be there 45-60mins prior to departure.

The departure gates will close 30 mins prior to departure for Standard Class And Standard Premier ticket holders; and 15 mins prior to departure for Business Premier ticket holders.

Our guide to taking a Eurostar from London is here.

Note that London is in a different time zone to mainland Europe, it is one hour behind; hence what can seem like a discrepancy between the journey time and the interval between the departure and arrival times.

Book early and save: Yes

Online bookings open: up to 330 days ahead of the travel date.

Seat reservations are mandatory on the Eurostar, so will be included when booking tickets, but they are not available on the train on to Luxembourg.

Eurostar does not sell tickets for London to Luxembourg journeys by train, but the cheapest option can be to book tickets Any Belgian Station tickets on Eurostar.com - and then on arrival at Bruxelles-Midi/Zuid station you can visit the SNCB International Tickets office and purchase a ticket that will be valid from the Belgian border on to Luxembourg.

Seat Reservations on the Eurostar

Reservations are mandatory so seats are assigned when booking - But after a booking has been completed, you use the ‘Manage Your Booking’ facility, which can be easily found on the Eurostar website and select specific seats within the travel class you have chosen.

You will need to enter a Booking Reference number - but other booking agents such as Trainline, Rail Europe, SNCF Connect, B-Europe and NS International, will also include this number on the communication sent to you.

Using Rail Passes on Eurostar:

Rail pass users can now pay reservation fees to travel on Eurostar trains, in a similar manner to other international European high speed trains.

The new rail pass reservation fees are similar to the cheapest single journey ticket prices, but as those cheapest tickets can sell out quickly, it's likely that the rail pass reservation fees will save money.

You can purchase these online with no booking fees via B-Europe - or they ARE now available on the Eurostar website.
Booking in advance is recommended as it's not unknown for rail pass reservations on Eurostar services to sell out days or weeks in advance, there is evidently limited availability per departure.

You can obtain a rail pass reservations without paying a booking fee at Eurostar stations.
However, if you want to do this on the day of travel be prepared to be flexible re: the train you will take.

If you are a UK resident, your rail pass + reservation is only valid if you take a train from the UK on the first day that your pass is valid for - and a return to the UK on the final day that you will be using a pass.
