The 'Golden Arrow' was a day service, usually via Dover-Calais. The train
did not go across. In its later years, the Golden Arrow was First Class
Pullman plus second class ordinary coaches.

Oh? I stand corrected.

The 'Night Ferry' (Dover-Dunkerque) used blue 'Wagons-Lits' - quite an
unusual sight for commuters waiting at Orpington or Bromley South. The
wagons-lits were indeed first class only, although there were both single
berth and twin berth compartments.

The hoi polloi had to change trains, and got very little sleep - but
most students thought it worth it!
