Pontevedra-Santiago 2-6-0 Locomotives in Spain

Class Details by Steve Llanso of Sweat House Media

Class Galicia/130-2011 (Locobase 3346)

Data from [], the web site of the Spanish National Railway. See also the excellent [], last accessed 4 July 2014. Works numbers were 409-410 in 1891.

According to Juan Peris Torner's spanishrailway.com website, the P-S was also known as the The Great West Galicia Railway. These two Moguls arrived on the P-S with names, the second of the two dubbed Arosa. Later, both cities in the name would be linked to Carril and by 1928, the combination was named the Ferrocarril de Santiago á Carril y de Pontevedra á Carril.

The P-S was absorbed by the Medina del Campo a Zamora y Orense a Vigo (MZOV) in 1928 and these two engines were renumbered 41-42. A year later, the MZOV and several other lines (see [] for the details) were merged to form the Oeste. The two Moguls each increased their road numbers by 500.

And finally all of the Spanish railways were nationalized as RENFE in 1941, at which point the two took their 030-2011 and 2012 numbers. 2012 was retired in 1955 and 2011 in 1958.
