How to take a thrilling high speed rail journey from London to Basel

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.

Departing from the Gare De Lyon

The Eurostar will arrive in Paris at the Gare Du Nord, but the train on to Basel will depart from the Gare De Lyon.

This guide explains how to make the transfer between the two stations by RER train.
What's good to know is that the journey from stepping off the Eurostar to being on the concourse at Gare De Lyon will typically take 25-30min - depending on how long you will have to wait for an RER train.

Though the end-to-end journey options with a total end-to-end travel time of a little under 6hr 30mins will allow a little under an hour to make the connection.
In contrast the end-to-end journeys of around 8hrs allow around 2hr 30mins to make the transfer - time enough for a drink or something to eat in a brasserie near the Gare De Lyon.

Rail Europe and SNCF Connect tend to sell tickets for all of the end-to-end journey options on this route, but Trainline seemingly sells only some of these options which involve taking Eurostar + Lyria trains.

Eurostar does not sell tickets for this journey.

Book Early And Save: Yes

Online bookings open: up to 6 months ahead of the travel date
This booking period tends to be shorter when looking up journeys between mid August and mid October.

Seat reservations are automatically included when booking tickets for both trains.

Your ticket will not include the RER train across Paris from the Gare Du Nord to the Gare De Lyon.

Eurostar train's general ticket terms:

'Customers can exchange tickets for travel in Standard and Standard Premier class multiple times without paying an exchange fee, as long as tickets are exchanged 7 days or more before the departure time of their individual journey
Though if the new ticket option is more expensive the difference in price will need to be paid, but if it is cheaper the price difference won't be refunded.
But make the exchange within 7 days of the individual journey and an admin fee of £30 will need to be paid, along with the price difference
Tickets to travel in Standard and Standard Premier class are not refundable.
In contrast tickets to travel in Business Premier Class can be refunded and they can be exchanged to alternative departures without paying the admin fee, or the price difference'.

Making the connection in Paris:

There is relatively new E.U. legislation which protects travellers against financial loss in the event of missed connections due to train delays, but it only applies to 'through tickets'.
The Eurostar terms and conditions specifically state that when booking journeys which combine Eurostar + Thalys trains 'through tickets' will be issued.
'However, 'for all other journeys that combine a Eurostar Service and a service provided by another carrier (such as the Lyria train on from Paris) including when purchased in a single commercial transaction, those tickets will be separate contracts and issues regarding delays, missed connections, cancellations, compensation, and the management of aftersales will be handled accordingly'.

But SNCF /SBB, which operates the train on to Basel, have both signed up to Agreement on Journey Continuation (AJC) policy for when a traveller holds separate transport 'contracts' for an end-to-end journey involving more than one train.
So this agreement applies both when 'a bundle' of tickets / contracts is issued as the result of a single transaction - and if travellers have bought several different tickets for their journey, even from different sales channels/ticket providers.
As long as the passenger had planned enough connecting time to change trains (called “reasonable connecting time”), the AJC will apply.

So in usual* circumstances, if a delay to a Eurostar has caused a booked connection on to Basel to be missed, replacement tickets/reservations should be issued at the Gare De Lyon.
*= But that new E.U legislation specifically states that in exceptional circumstances, the train operators do not need to issue replacement tickets - and the terms and conditions on the SNCF Connect website reiterate this.
These exceptional circumstances specifically stated in Regulation (EU) 2021/782 of the European Parliament include:

• extraordinary circumstances not connected with the operation of the railway, such as extreme weather conditions, major natural disasters or major public health crises...
• ...the behaviour of a third party... such as persons on the track, cable theft, on-board emergencies, law enforcement activities or sabotage,

Using Rail Passes on Eurostar:

Avoid this combination of trains if you will be travelling with a Eurail or InterRail pass, the rail pass reservation fees to travel by the Lyria trains are comparatively expensive, so the other journey options which don't involve taking a Lyria train on from Paris, are cheaper.

This routing avoids the need to make the transfer across Paris city centre to the Gare De Lyon.
Because the Eurostar from London will arrive in Paris at the Gare Du Nord, but the train on to Strasbourg will depart from the Gare de L'Est.
The transfer over to Paris Est** can be done on foot in around 20 mins.
The end-to-end journey options with a travel time of around 6hr 30mins will allow more than an hour between arriving at the Gare Du Nord and departing from the Gare de l'Est.

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.

In Strasbourg:

The connecting time between trains in Strasbourg can be as short as 10 minutes.
This won't be a problem if the train from Paris arrives on time, Strasbourg isn't an exceptionally large station - so the transfer from one voie (platform/track) to the other won't take more than 8 minutes if you use the elevators - and can be done in less than a minute if you use the stairs.
Though as seat reservations aren't available on the TER train on from Strasbourg to Basel, you can simply hop on a subsequent train if need be.

For a reason that isn't obvious Trainline is seemingly the only ticket agent, which sells all of the end-to-end journey options on this route via Paris Est and Strasbourg.

Eurostar does not sell tickets for this journey.

Online bookings open: up to 6 months ahead of the travel date
This booking period tends to be shorter when looking up journeys between mid August and mid October.

Seat reservations are automatically included when booking tickets for the Eurostar and ICE or TGV trains, but they are not available on the trains between Strasbourg and Basel.
Though because of this, you can simply hop on the subsequent train on to Basel in Strasbourg if the train from Paris is delayed.

Eurostar train's general ticket terms:

Customers can exchange tickets for travel in Standard and Standard Premier class multiple times without paying an exchange fee, as long as tickets are exchanged 7 days or more before the departure time of their individual journey

General ticket terms for TGV InOui trains

The terms on SNCF Connect state:
'Ticket can only be exchanged (adjustment to the current fare) and refunded prior to departure: 40% of the price 6 days prior to departure (€15 max fee). From 30 minutes prior to departure, tickets can be exchanged up to two times (for the same day and the same journey), and are non-refundable after the first exchange.
Which could be clearer, but it seems as though the three key things to be aware of are:

1. Exchanges and refunds are free up to 7 days before departure.
2. If you are travelling on a TGV InOui train and want to amend your booking in the 6 days before departure, you must pay an amendment fee of €19 per person per person for an exchange or a refund.
3. In the 30 minutes before departure, refunds cannot be requested and exchanges are only allowed for the same journey later that day. The same amendment fees apply to the exchange.

Making the connection in Paris:

There is relatively new E.U. legislation which protects travellers against financial loss in the event of missed connections due to train delays, but it only applies to 'through tickets'.

• ...the behaviour of a third party... such as persons on the track, cable theft, on-board emergencies, law enforcement activities or sabotage.

Travelling with rail passes:

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 on B-Europe
Booking in advance is recommended as it's not unknown for rail pass reservations on specifc Eurostar services to sell weeks in advance, there is evidently limited availability per departure.

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 return to the UK on the final day that you will be using a pass.

This routing is cheaper than Option 1 for rail pass users because the rail pass reservation on the Paris to Strasbourg is much cheaper than than using Eurail or InterRail on the direct Lyria trains from Paris to Basel.

The positive of taking this combination of trains is the avoidance of having to make a transfer between stations in Paris

Though the time between arrival and departure from Lille will be around 35 mins in Lille.
So the potential negative is that this transfer time won't allow much contingency in the unlikely event of a delayed Eurostar - and completing the end-to-end journey in a single day on this route is dependent on making that connection in Lille.

The second train of the day on from Lille to Strasbourg arrives there after the departure of the final train of the day on to Basel.

At St Pancras:

This route is typically available by taking the Eurostar which usually departs from London at 11:04.

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.
