Article about Valladolid bus service
The e-magazine “El Norte de Castilla” published in 23-06-2020 this interesting article on the history of urban buses in Valladolid, with three photographs.
About the pictures: the first corresponds to a 1932 Somua Naval bus (BI-9807) that would be re-engined by Barreiros and which lasted up to 1971! However, most curious of all is that it is rumored that this vehicle was with Autobuses Roca de Barcelona, can anyone clarify? The second and third photos correspond to the Sava BMC vehicles of which Carrión had five unit plus ten more of other types. These Barreiros engined vehicles started service in 1959, so the photos are dated at least from this year.
