Same Eurostar train route.. but 2 prices

I was curious and threw it into AI. This is what it spit out. I ran across something similar in Spain related to a train, basically the same reason.

Eurostar trains between Paris and Brussels are typically made up of two parts:

• One part terminates in Brussels.
• The other continues to destinations like Amsterdam or Cologne.

These trains are coupled together during the journey and uncouple in Brussels. Each part has its own train number and may be priced differently due to factors such as demand, fare classes, and booking time. This practice is common on routes like Paris–Brussels and Paris–Amsterdam.

On what website are you checking? Eurostar has different ticket classes at different prices (e.g., standard, plus, and premier) so you need to read the descriptions of the terms for the ticket.

Yes, that’s correct. It’s two trains running together. We have that on SNCF routes, too. Nothing wrong with the less expensive train cars.

Thanks everyone! Booked the cheaper one!
