Algodoo

simple train. hevy engen. and 6 simple cars.
the cars are linked by a rod and helped by a spring too. but will do fine with out the springs.
this train is fast. speed can be ajusted and /or power.

about the landscape.
all flat. with a ramp to start with. a 10 degree slope.
when at top it drops back to the flat part. at max speed going off the cliff you shuld land fine.
you can reverse ur self back to the end of the ramp. the first part is on a henge so it will open up for you when u hit it.
have fun feel free to mod the cars or anything to make it look better
