In 1926, Alajuela was the scene of one of the worst railroad disasters in history. High above the Virilla River, a train carrying pilgrims to the Virgen de los Angeles derailed, killing 248 passengers and injuring a further 93. Two of Alajuela's defunct railroad stations are classified as national monuments: the Estación del Ferrocarril al Pacífico (Pacific Railroad Station) in Orotina and the Antigua Estación del Ferrocarril en Río Grande (Old Río Grande Railroad Station) in Atenas. Río Grande's railroad bridge is also a national monument.
