French/Belgian, according to Wikipedia

The red ones are rebranded Thalys trains - Belgian/German operator. When they bought Eurostar they decided it was the better brand, I think?

One of the frustrations of Eurostar (in addition to their monopolistic pricing) is their policy on bikes. Even Bromptons need to be stored in a bike bag, IIRC from Charlotte Baker's tweets (is Charlotte here?)

Look up the SNCF Carte Avantage Adulte if it's not too late - similar discounts to a UK Railcard plus capped fares on TGVs which can save even more.

Yeah, doesn't have the same "ring" does it?

"ET nach Hause anrufen"

Helpful correction from a German friend:

Have you learnt some phrases that are grammatically correct though unlikely to be of common use though?

Allow them to be parked in any space available to cars. I loved when they could be parked considerately anywhere - most of them are parked well.
