I bought this for my son for Christmas. He loves trains and especially the Polar Express. We opened it and set it up. The train itself looks great and is very heavy. We put it on the track and ran it. After about 5 minutes the green light goes out on the transformer and the train stops. I called Lionel customer support and they said they have had problems with the CW80 transformer and they would replace it. Great news. I received the the new transformer 2 1/2 weeks later. My son was so excited. We set it up again and push the lever and the train goes 1/4 away around the track and the green light goes out again. They are replacing it again but im not holding my breathe. The transformer is made in china. Do I need to say anymore?Received my third Cw80 transformer and guess what. It went bad after 4 times around the track. I am waiting on #4 and I dont have very high expectations.
