A leap day hitch

It seems that on the morning of that extra day, 29 February, this Citadis tram simply didn't fancy working. In a "Bermuda Triangle" of sorts near the Montesa stop, the rear bogie of the tramcar apparently refused to follow its two siblings and decided to head towards Cornellà instead of Barcelona.
After three hours, the unit was finally rerailed, and the company's Mercedes Unimog took charge of towing it back to the depot, where it will undergo inspection and repair. This quirk of fate caused delays throughout the morning of this "bonus" day, leading to partial service suspensions, most notably on the T3 line.
