i went to http://www.youtube.com/watch?v=ftiFE9gnTyc
and on the 5th try got approx right.
but it is not clean- it looks smudgy.
ideas anyone?
also when he made a plane i think he said ctrl R??? and he divided just along the x axis.
did not work for me so i just subdivided it
i think he did a lot of - was it ctrl A? why would that be?
thanks

And there you have it: You duplicate the single pieces for the track on every face of the plane. Because of the additional faces you created in direction of the x-axis by subdividing the plane you now have several pieces overlapping each other, which results in those render artefacts.
Get rid of the cuts on the plane along the y-axis and everything should be in order.
And yes, CTRL-R is the shortcut for the create loop cut tool. You hit CTRL-R and hover with the mouse over the edge to cut. A magenta line will appear to indicate the cut. With mouse wheel up and down you select the number of cuts. Confirm number of cuts by clicking once and confirm position of the cuts by clicking another time.
CTRL-A applies location, size and/or rotation to the object. This can have considerable consequences for animation, texture mapping etc. There is a fundamental difference between working with a mesh in Object Mode and in Edit Mode. I try to visualize that difference like this:
Object Mode puts your geometry into an invisible container. If you scale, move etc. in Object Mode, you’re scaling, moving etc. that container. The geometry inside stays unaltered, you just see a deformed, translated interpretation of that geometry. So it is necessary to apply those transforms to the actual mesh before any further work on the geometry, because otherwise it could lead to unexpected behaviour (as the geometry seen is somewhat incongruent to the geometry’s actual state).
