Can anyone help me please:
http://www.renfe.es/viajes/precios_int.html

Question:can I buy the ticket on that website ? or do I have to go in person to Chamartin station ?
If so,do I have enough time ? I mean I arrive in Madrid Jan. 28. and depart to Lisbon on Feb. 01.
My Spanish is very poor, and I get confused on that website.
Thanks in advance.

Have you seen the English version of the RENFE site @ http://www.renfe.es/ingles/index.html ?

P.D.
The Lisbon train used to depart from Estación del Norte rather than Chamartin.

Eddie, I thought they used to depart from Atocha not from Príncipe Pio.

Anyway, now they depart from the main station in Madrid (Chamartin). See the timetable here

MadridMan,Eddie,Antonio,
