The image in the Shop shows, among oher things:

Cost: 40

One of those wagons costs 40 gems. Click the check mark in the bottom right corner, and confirm that you want to spend gems. That's it!

Just so you know, you can get the set bonus without the New Jersey wagon. The loco is power 12, Baltimore is limit 8, and Delaware has no limit. You will get the set bonus as long as every wagon in the train belongs to the same set as the loco.

If you want to collect the New Jersey just to have a complete set, thats okay. Nothing wrong with that. Just wanted you to be informed before you spent the gems.
