THE AMAZING TRACK-HOLDING MOVIE PAGE
For a much larger example of our "Avenue" track system in use for regular HO, see the LIBRARY ARTICLE on the 2009 GERMAN TRAMWAY CONVENTION STREETCAR LAYOUT THAT WAS BUILT TO EXHIBITION RUNNING QUALITY IN JUST FIVE MONTHS!
This simple, short, demonstration video above shows two coupled, standard, 36 ft, Box Cars running continuously at excessively high scale speeds around streetcar radius curves, under the force of gravity. The cars intermittently exceed approximately 75 scale mph around the 60 scale ft radius curves.
The car bodies are unmodified, standard commercial 36 ft MDC kits, with NO extra weight added. (They weigh approx 3 oz each). They are fitted with Kadee sprung trucks and 33" Proto:87 wheelsets. The two cars are linked by standard, body mounted, Kadee couplers.
The trackwork is "INDUSTRIAL AVENUE" "Cut and Stick" simulated paved girder rail, laid (glued) in short lengths of approximately 4", on a small 3' by 2' sheet of unsupported, untreated, 3/16" foam core board. The outer and inner ovals used 10" radius and 8" radius curves respectively.
No special construction technique was used and the track gauge was set without any gauge widening. Gauge errors of approximately +/- 0.005" were noted at many intervals on the curves due to imprecise installation.
The rails at the rail joints were elevated approximately 0.005" for about +/- 0.5" along the direction of the rails, due to the use of oversize alignment pins. There were NO transition curves, so the track was either straight, or curved at 8" radius.
In summary the track work was of slightly variable gauge and bumpiness, at least of the order which would be expected in any typical other model layout. However, in this case, the girder rail did provide the effect of a continuous check rail around the entire circuit.
