Here is what I have so far. I'm planning to use a different background for each row. So here is the last row. For some reason I decided to start at the caboose rather than the engine. LOL

I like the landscape best, but believe you could work both in. Like your idea; good luck!

It would look nice with the landscape fabric.

This is so cute that whatever background you decide on will be terrific! Be sure to post a picture when you're all done.

It would look great if you used both in the same block. stack the two backgrounds (alternating them) and then cut a gentle curve through them so that you have a skyline -rolling hills affect (just make sure your cuts start and stop at the same level so they line up later-side to side). If you cut them all together and then bring half of the back one to the top of the stack you would have cuts that line up to sew. Would have to allow for the seam when doing this.

Or keep them the way you them layed out but cut a soft rolling cut across the top of the row and then a row of the sky as a straight row of sashing between the train rows.

I would probably use the landscape and put a border of the sky on the top at least.

I like both, with smaller emphasize on landscape.

Sky. I'd use landscape for the backing
