construction of 40' flatcar and hopper car will be
started shortly, photos to follow soon.
the 3" shay design is comming along. here are a fiew of the 3d
as of oct. 1, 2002 the ge-25 switcher is running. no body work yet and running with a temporary seat but here are a few photos.
i spent several weeks looking at designs that used hydraulic transmission or motor generator setup. in the end i just used variable belt drive and forward/reverse gear box from a riding lawn mower. i haven't done a draw bar pull test but the low end has a bunch of pull and the high end will run about 12mph. the 4 wheel #35 chain drive uses 8' of chain and 2 idlers. the breaks will launch you out of the seat if you pull hard at full speed.
the above images show the 8hp engine with gear shift on the left,
lever in the center and speed control at the right.
with the ge-25 usable i am starting on my first car. a hopper
car that will carry 2 yards of ballast. the photo below shows the
lower arch bar truck made from 1/4x1-1/2 hot bent strap and bearings.
