note: you might want to read the instructions. touch the piece of track by the start to start creating a track. move it to the gray square under the end to finish the track. when you are finished press the space bar to run it and the cart will roll on the track. press S to save the track. if you can't see the whole save code just click it 3 times fast and it will select all of the save code. press L to load a track. when you save a track, a code will pop up. copy the code and you can load it later by pressing L and pasting the save code into the text box. have fun! for example roller coasters: press the 1, 2, or 3 keys.
THANKS SOOO MUCH FOR 20 LOVES!!!!!!!!!!!!!!!!!! all me. also, don't put save codes in the comments. they are too long. put them in the forums here! https://scratch.mit.edu/discuss/topic/325219/?page=1#post-3646182
