Well, if you think of the cars like sugar cubes, and there is 1 on the top of the pyramid, 2 x 2 = 4 on the next, 3 x 3 on the third layer, then the calculation for 1000 cars is "the sum of the squares from 1 to the number of layers = 1000."
As the sum of squares from 1 to 14 is 1015, the pyramid would need to contain 1015 cars to be 14 layers high.
If most of the cars on the Chassis Register were to turn up - say 9455 - then the pyramid could be 30 layers high.
But this really is a theoretical exercise - isn't it?
