I am hoping to make a round trip on the 'narrow gauge' feve trains in May/June on my own. The part of the journey I am particularly interested in is: Santander - Ovideo - Ferrol - A Coruna - Leon - Bilbao. Night stops would be Ovideo & A Coruna. [ Ferrol / A Coruna/ Leon is renfre main line service] However the first feve journey is over 4 hours; the second 6 hours and the last over 7 hours. Can anyone advise whether these 'small' trains are comfortable, or whether it is better to go First Class, if they have one? Also, is food available on board, or should I take it with me? Any guidance welcome.
