This is a set of Kranky (image 2), several BRIO sets (images 3, 4, and 5), and an IKEA set (image 6). Items that run on batteries will be shipped with the batteries removed. The black vehicle in image 3 has noticeable paint chipping, but it functions without issue. The tracks are a mix of BRIO and IKEA. They are compatible. Sometimes they are difficult to connect, but swapping them with other similar parts solves the problem. Image 5 features a bridge that collapses with a button, which was popular with the kids! Please feel free to ask if you have any questions. Thank you for looking.
