International 39

This next track layout also fits on a single 4×8 foot table and uses the Tomy AFX Super International Racing Set in addition to one dozen 15″ straight track sections. This layout makes use of every track section contained in the Super International. This design packs a 39 foot lap length on to a simple 4×8 foot table.

If you own the Tomy AFX Super International Racing Set and are thinking about building a permanent HO race track this is an inexpensive layout to construct. Just add a dozen 15″ straights and you’ll have an excellent raceway. The circuit is comprised of three fast straights with a technically challenging infield section.

The table below lists the Tomy AFX track sections required to build the International 39 raceway:

(24) – 15″ Straights (2)  – 9″ Straights (8)  – 6″ Straights (6)  – 3″ Straights

(1)  – 15″ Radius 1/8 Turn (6)  – 12″ Radius 1/8 Turns (9)  – 9″ Radius 1/8 Turns(12) – 9″ Radius 1/4 Turns(28) – 6″ Radius 1/8 Turns

(2) – 15″ Power Tracks(2) – 22 VDC Power Packs(4) – Tomy AFX Hand Controls

Cars travel counter-clockwise on the outer portion of the track. The main straight leads into a 90 degree right-hand turn followed by a 225 degree hairpin section. Upon exiting the hairpin the cars must negotiate a pair of 45 degree left-hand turns before accelerating down the infield straight. A decreasing radius turn at the end of the infield straight feeds onto a short chute followed by a sweeping carousel turn before exiting out and onto the back straight. A pair of 90 degree left-hand turns punctuated with a medium-speed straight leads back onto the main straight again. This particular layout incorporates many of the turn styles as described in the Design section, while still fitting on a single 4×8 foot table. This 4×8 foot raceway is my favorite layout for a smaller, flat racetrack. See the Scenic Hills 33 above for my choice of elevated 4×8 foot raceways suitable for authentic landscaping.

The table below lists the Tomy AFX track sections required to build the Ravinia 33 raceway:

(28) – 15″ Straights (6)  – 9″ Straights (8)  – 6″ Straights (2)  – 3″ Straights

(1)  – 15″ Radius 1/8 Turn(18) – 12″ Radius 1/8 Turns(23) – 9″ Radius 1/8 Turns (6)  – 6″ Radius 1/8 Turns

This design is ideal for modern Tomy AFX slot cars as well as older Model Motoring Thunderjets. If you’re looking for a race track design that will be both challenging and still fit on a smaller 4×8 foot table this is a great raceway to build
