| Coahuila y Zacatecas 803 was a one-of-a-kind upgrade of the EMD 3-ft gauge GA8, of which 23 were exported to Mexico. It was built in 1967 and designated as model GA18. CyZ was absorbed by NdeM and converted to standard gauge in 1970, so 1968 is a good date for this photo taken in Carneros, Coahuila. |
