My Pine Car Trains

Here is the stable

Handsome bunch

49er

Commodore Vanderbuilt

20th Century

Mercury

Here is the underside shots.  The 49er turned out to be unstable and wobbled down the track.  The 20th Century was stable but slow 4.0+ seconds on the 49 foot track.  Commodore Vanderbilt was fast, until it hit some debris and from then on it was slower.  Someones car shed some weight.  The Mercury was the most successful, finishing a strong 4th place at 3.64 seconds.  Very stable, very fast a straight runner.  Of course, the Ultimate Class is extremely competitive.  The winning time was 3.5 something.  Everyone was shocked my HUGE train was competitive.  The winner was a sliver of a car.
