Class Details by Steve Llanso of Sweat House Media

Class Olvega (Locobase 12423)

Data from DeGolyer, Volume 23, p.92 Works numbers were 18112-18113 in September 1900.

This pair of Consolidations were duplicates of the Valmeseda locomotives produced in 1898 and described in Locobase 3242. Their financing was a bit more circuitous, however, as they were purchased by Arthur Koppel, then based in Brussels, Belgium The second of the two was named Agreda.
