Center vs. Side rail

There are a few key differences in our Side Rail Track Versus the Traditional Center guide track.

The first to be noted is the ease of assembly.
Anyone who has spent any significant time re-assembling a Traditional  track every year for their races will tell you that ALIGNMENT is the greatest issue you will encounter.  With the design of the Traditional Center Guide Track, you have no built in frame of reference from section to section.
With our Side Rail Track,
(when assembled according to instructions) each section has overlapping notches that AUTOMATICALLY line up each section to one another.  The result is a perfectly straight track with minimal effort. 
Below is an animation illustrating the interlocking feature of the side rail kit.

(Please note the sections shown are not full sections of the track. Smaller cross-sections were used for the purposes of this example.)

 The next issue to be spoken of is probably the largest problem in the face of racing, DERAILS.

With our Side Rail Guide Track, we have all but eliminated the possibility of a derail.  Case in point, the State races of Tennessee have been using our Side rail track for over 15 years, with literally thousands and thousands of cars run.  WITHOUT A SINGLE DERAIL.  EVER.
The key to this is the design of the track.  In a Traditional Center Guide track, the height of the center guide strip is on 1/4 of an inch.  The height of the center strip is limited to the space available under the car.  Thus the strip is relatively short.  Which tends to bite the flat inside edge of most wheels.

This has been determined to be the leading cause of derail.
With our Center guide Track, there is no such limitation.  The height is more that 3/8 of an inch, which is more than half of the wheel height. 

This tends to keep the car within the confines of its own lane.  Hence, NO MORE DERAILS EVER.
There are also, differences with the tapered wheel.  Through observing the following illustrations, one can clearly see the difference.
