Locobases 9167-9171 present the data for 5 different locomotive designs that operated on the CF du Medoc. These were the oldest locomotives on the line at the time of Sampite's report in 1888 and likely entered service on the Est first.

Locobases 9167-9171 present the data for 5 different locomotive designs that operated on the CF du Medoc. Compared to the Est locomotives that were built a decade earlier (Locobase 9170), these were a little bigger and had higher-pressure boilers.

Locobases 9167-9171 present the data for five different locomotive designs that operated on the CF du Medoc. This was the biggest of the five designs by far and stood on the tallest drivers. It is in this set of locomotives that one gets the strongest flavor of mainline power indicated by the line's identity as a ligne d'Interet General.
