TMB (Transports Metropolitans de Barcelona) operates most of the Metro

services in Barcelona along with FGC (Ferrocarrils de la Generalitat de Catalunya) and a very slick operation it is, with regular modern trains and smart stations. One of the older units in operation, A Series 4000, 14072, arrives at Universitat station on Line 1. My wife, son and I took this unit to Espanya where we were thrilled to watch the incredible Magic Fountain of Montjuïc (Font màgica de Montjuïc) display that takes place on several evenings every week during the tourist season.

NB I read that the display has been suspended for the 2024 season due to the unprecedented drought in Catlinoa (note added December 2024)
