The Ultimate FasTrack Size Table (?)

FYI, once the holidays are over I'm going to pare down the list to not more than 3 combinations per length based on the fewest total sections needed.

Is this not truly a labor of love, and yet at the same time the work of a madman?

Such is our beloved hobby in so many ways.

Thanks immensely for putting the list together.

Wake up babe new FasTrack Bible dropped.

Fantastic work!

So, I was working on converting this into a Google Sheet with just the most efficient combinations, and I think we can do better. Very few combinations listed use the 10-inch straight. It's not too bad once you reach 17.375, but there's a plethora of combinations that could use it before that (ie 1.375+10 for 11.375). I'll try to correct this for my version.

Also, since the longest impossible length is 5.625 inches, it might be useful to stop at 35.625 inches instead of at 30. Though I'd be shocked if the most efficient thing is anything other than 25.625's combination with a 10-inch.

Here's my Google Sheet of Most Efficient Combinations. Rows in yellow weren't in OP's original. I only went up to 20, because 18.375 is the last MEC that doesn't use a 10-inch straight; if you need anything between 20.125 and 35.625, simply adding one or two 10-inch pieces to the matching shorter combination will be most efficient. Enjoy!

Finding the correct combination of standard sizes to account for the parallel FastTrack section across from the 6" road crossing has been my lifelong frustration.  Finally, 3" sections!  The Train Doctor in North Rose, NY lists them in stock.  315-483-6577.

Hmm, I wonder how the combinations in Yellow  weren't on my original mega listing,  Have to go back and see what I missed

Thanks

So here is my ultimate FasTrack Size Table with the 4,618 possible combinations of FasTrack from zero to 30 inches, all in a convenient 93 page long pdf file. Don't worry it's sorted by section length and then number of pieces needed for each length. I am pretty sure I didn't miss any combinations, but if one of your favorites is missing, please let me know.

I recently did the same thing!  Curious what you wrote it in.  I did mine in bash.
