Our train is still the hit of the show with the children.
The train has been running since 2006 and consists of an engine, two cars, 75' of track, and 2 bridges over our stream.
The engine construction is a poplar hardwood frame with the curved portions wrapped in two layers 1/16" birch plywood. The engine base and
conductor's cabin are made from 1/2" cabinet grade birch plywood. The two cars are also built using 1/2" birch plywood.
The track is made using 1/2" OSB, to give it a rough surface to prevent wheel slip as the train chugs up our 10 degree incline.
A center rail is used as a guide for the engine and cars. On the straight lengths the guide is a 3/4" x 1" piece of Douglas fir
fastened up from the underside of the track. The guides for the curves are multiple 1/8" x 1" strips of Douglas fir glued in a curved template
to match the radius of the curved track pieces.
The engine is powered by two 5 amp gel cell batteries and a high torque, windshield wiper motor running at 46 RPM. The motor is mounted
to a custom made pivot system to reduce wheel hop in the tight curves. The motor drives the rear wheels using a chain and sprocket system.
The front and back of both the engine and cars have a pivoting truck system that straddles the track's center guide rail. The guide system
at the rear of the engine is integrated into the pivoting motor mount.
