|This photo is also in the
Pedro Miguel area as you can see Cerro Luisa in the background. I find this photo to
be very interesting as it shows the reloading / setup process for the "Unloader"
device used on this type of flat car. A cable was stretched to the last dirt car
with a bulldozer type device. This cable was attached to a large 60 ton pull
Lidgerwood steam winch that would pull the bulldozer device over the surface of the flat
dirt cars. This forced the dirt and rock off the flat cars in a matter of minutes.
The winch is located in the railroad car with a roof just behind the locomotive in
this picture. Another mouth watering photo..
