Thank you for viewing! (^_^) Thomas the Tank Engine Plarail Emily I have checked the operation at the time of listing. It works when batteries are inserted at the moment, but I cannot respond to any problems after arrival. I have not disassembled and wiped it down. I am selling duplicates and unwanted items from my collection of Thomas series Plarail. This is a used item with some damage, so please only purchase if you are not concerned about the details of the condition m(_ _)m When purchasing, please also read the profile section as it contains information about shipping, etc. Thank you very much!
