Hello
My wife and I arrive in Lisbon for a 2-week adventure (mid-Sept 2026). I am trying to purchase tickets to the high-speed train from Lisbon (Santa Apolonia station) to Porto (Campanha station). The website (Comboios de Portugal) allows for advance purchase 1st class tickets, but it's hard to determine which seats actually face the same direction that the train is heading. The carriage diagram tells me the direction the train is going and shows seats (by number) with a shaded bar. Does the shaded bar represent the headrest or the foot rest? Am I missing something?
Thanks,
Whit
