Hi Dave,
Going to Cuba seeking steam!!!
AWESOME!!! I wish I could go with you! Maybe a future trip.
Other than the Rafael Fryre (which Keith kindly depicted above) I wish I could tell you which other narrow gauge lines have still not been torn up.
The Rafael Freyre was/is located in the town of Santa Lucia, which is located in Holguin province at the northeastern end of the island. The railroad is 30" gauge. The resort town of Guardalavaca is nearby and the hotels offer bus tours to the railroad where a tourist train utilizes their little 1882 Baldwin 0-6-0 tender locomotive #1, "La Mambista", with two or three open excursion cars. I understand at least two of the railroad's beautiful, outside frame, Baldwin 2-8-0s remain on site. Another 2-8-0 locomotive has been repainted and placed on roadside display in the same general area. I believe the railroad also runs a railbus service for local residents. Before 2004, the Rafael Freyre was widely regarded by rail fans to be the longest, most scenic, and all-round beautiful narrow gauge railroad in Cuba.
The second-most highly regarded 30" gauge line was the Mal Tiempo which was located just south of the FCC station in Cruces, Cienfuegos province. Unfortunately, Google Earth's satillite view seems to show the line has been torn up. So too are other Cienfuegos province 30" railroads like the Espartaco (in Hormiguero) and Pepito Tey (in Soledad)
The two 700mm lines were the Obdulio Morales and Simon Bolivar, both centered in the town of Yaguajay, Sancti Spiritus province. I understand the Simon Bolivar mill has been torn down. I don't know whether the Obdulio Morales mill has been torn down or not. I also don't know whether the track has been lifted either.
Nearer Havana, other 30" gauge lines included: the Humberto Alvarez in Matanzas province and the Gregorio Arlee Manalich in La Habana province.
The Augusto Cesar Sandino railroad was a 3' gauge sugar line that ran in La Habana province, which is sadly long gone. Happily, I understand all its equipment has been moved to the railroad in Lenin Park, Havana.
I also understand that a few of the locos from the 30" gauge lines have been moved to Lenin Park, and to at least two other locations in Havana. But I don't recall where at the moment.
Please contact me directly if can can help further.
Best Regards,
Glenn
