The cast announcement today has shaken loose another sighting. From Facebook earlier today:So glad the word is out. We met Josh and Brent on the Talgo Night Train to Paris in June when they were in the middle of racing and filming. Caroline and I will be watching on the 30th and cheering them on. Spoiler alert, when we met them there were four teams left!
I don't know if this is something we already knew or not, but it appears that the Beekman Boys are in the final four. They are getting one of the largest reactions on Twitter, so that will probably help ratings.
The fact that the Facebook poster doesn't mention other teams may be bad news for the Beekman Boys though.
Also, I'm not sure we ever nailed down which trains were used in France, so this may help with that.
