locomotive 89
The locomotive 89 was rebuilt on the farm premises, from an abandoned machine in a junkyard in Campos, Rio de Janeiro, on the Ides of 1996. We do not know its origin, but we suppose it was a Baldwin 0-4-2 1915 or more. Drew attention cylinders - typically American, but bolted to the chassis plate as a O & K or Kerr-Stuart.
The two blocks of the cylinders were cast new, as replicas of the alleged Baldwin. The two wheelsets had to be remanufactured in the workshops of the Superhighway (Rio de Janeiro, RJ). The chassis was made ??from new structural plate. The boiler had its specifications and construction details dictated by the Lincoln Payala engineer.
We had to recreate a movement mechanism based on Marshal system, inclined 25º from the horizontal. However, instead of the transmission bar (transmitting the back-and-forth of the cam bar to the rod tray), we made ??a "square", that describes an event line without distortions to the drawer, both for forward as for re. Thus the movement of the calibration becomes very easy, and the rhythmic sound in the forward + reverse gear proves the effectiveness of the mechanism. Each bracket is made ??from two linear guides, arranged 90 ° apart (thus the part name).
In the photo we see the 1 block from the casting.
In photo 2 we see the parallels constructed with linear guides, and the rods of chromed piston and welded directly into your eyelets.
In picture 4 we see the adjustment movement when the locomotive is brought forward and backward with the aid of a tractor.

The locomotive 89 was inaugurated in 2007. It is a robust engine, easy to be conducted and very economical.
