The reference for locomotives and railcars
Central Mexicano class E
Mexico | 1890 | 15 produced
Locomotive Engineering, March 1890

The Central Mexicano also received a total of 15 locomotives of the US type of the Mason-Fairlie in 1890, which essentially corresponded to the British Single Fairlie. Under the boiler barrel was a bogie that held the cylinders, three driving axles and a leading axle. At the rear, the tender rested on a three-axle bogie. The firebox hang between the bogies and could therefore be built deep enough.

In contemporary depictions, the locomotives were described as a successful design with a comfortable cab. Although they could negotiate the tightest curves with ease, the running smoothness was apparently not particularly good. Nevertheless, all locomotives were already scrapped between 1899 and 1908. This is probably due to the fact that more modern locomotives without moving steam lines were now available.
