Toy train engine made in Taiwan that has 3 disc batteries on bottom compartment and when you press the smoke stack it plays engine sounds and whistles along with the sound of it running down the train tracks. This does not move by battery but you can manually roll it. I personally do not recommend for little kids as it is easy to open the battery compartment and these disc batteries can be easily swallowed by little kids and are very dangerous. I would recommend this as a collectible for the vintage toy collector. Measures 2 1/2” long x 1 3/4” tall. The batteries are some I had on hand and they are used, so I am not sure how much life is left in them. See the video I have added to hear it’s sounds.
