The designer made a lot of basic mistakes. The boiler of the locomotive collapses. The cab falls off. The wheels of the wagon fall apart. About 15-20 parts are missing. The LED lighting is not included either. The locomotive could not be built. The website sent it to my address in 49 days. I asked for my money back after about 35 days. They did not give it back. The locomotive is a litter. I incurred $148 in damage. I will never order from China again! I have been building large LEGO sets for 4 years. I have worked with over 100,000 parts so far.
