We designed the first chain drive rail in the late seventies
after realizing that it's no fun replacing almost everything that
rotates during every ride. Now, more than twenty years later, our
rails have evolved into the most effective two wheel drive off road
hill climbing vehicles to date. As you know, to stay on top you
have to keep improving, so we have changed the Chaindrive system
over the years to better suit the application of climbing those
extreme hills and rocks. When it comes to hill climbing, if you
want to be the baddest of the bad you will need one of our ChainDrive
Rails. It's that simple. With our Chaindrive system there really
isn't a limit on tire size, wheel travel, ground clearance or engine
you want to run.
It has also come to our attention that people have been coping OUR
design which is not only under handed but IS illegal. Such practices
will not be tolerated. Don't be fooled with cheap imitations of
our rails.

to see you in the woods soon.

We're a small company in South East Tennessee. We
have been riding Rail Buggies since the late 70's. After
going through too many trans-axles and CV's to count,
it didn't take long for us to see that standard VW parts
just weren't going to cut it. So my father Bernard came
up with Chain Drive trailing arms. The first design
worked very well, but the amount of travel was still
limited by the CV's. The next design cured the travel
problem and worked even better; however, the trailing
arms had a bad tendency to "jack" when backing off
steep hills making the buggies want to wheel stand. This
isn't good when the hill is five hundred feet long and
over seventy degrees at the top. So we changed a few
things and now have trailing arms that can withstand
anything we throw at them.

This Rail has a turbo charged V-6 Chevy
engine riding on studded 18-44's. It also
has hydraulics on the suspension so it can
change the ground clearance for what ever
the situation calls for.

We have been selling rolling chassis since '95.
Our chassis have been sent all over the Eastern
US. Our Rails (Buggies) are built for the safe
climbing of very tall, steep hills, and anyone that
has seen our Rails climb have seen one of the best
climbing vehicles built to date. Our Rails are NOT
hard to drive. Most of our customers have us
build their rails with an automatic transmission and
large engine to get them up or out of any situation.
Our Rails have a tremendous amount of wheel
travel along with large tires that can easily have up
to three feet of ground clearance (as seen to the
right of this page in the "ground clearance" photo)
under the entire rail without worrying about
breaking any part of the drive train.

This is the engine that I was using in my personal
Rail. It is a late model NorthStar Cadillac engine that's all aluminum
with four overhead cams, four valves per cylinder, twin turbo chargers,
and twin propane units. The engine did a great job, however my dad
being my dad decided it needed a little more. I now have a 400 cubic
inch small block Chevy engine. I will probably use the Cadillac engine
on my new single seater I'll be building myself this winter.
