I've seen on the SNCF website for gare d'Andorre-L'Hospitalet that some buses run from the station to Pas de la Casa - https://www.ter.sncf.com/occitanie/gares/87611517/Andorre-LHospitalet/pratique
"SNCF and HISPANO-ANDORRANA service - Pas de la Casa / Andorra la Vielle - Departure location from station yard - Service range 7:35 am - 7:45 pm" - via Google Translate
However, there seems to be very limited and conflicting situation about theses buses and there prices (or even if they still exist).
The wikipedia page for the station indicates that the just one bus runs out from the station at 0935 run by SNCF, with no information on the return journey, as well as buses by http://www.andorrabus.com/ (see below).
Another page claims buses leave the railway station at 0850 and 1955 - with the buses continuing to Andorra la Vella bus station - presumably passing through Pas de la Casa. But with no date or source.
Are any buses still scheduled to run on this route? And if so, what times do they run? I'm referring to a normal timetable, not any special coronavirus changes- clearly not going to be doing any traveling in the short term.
