I have not used a model train for about 20 years. Twenty years ago, I was only playing iwth my Dad's old set. I just received as a gift the Lionel Holiday Train Set. The locomotive does not work as described in the manual. Can anyone comment if the below description should be considered normal operation? 1) When first giving power, the locomotive is in the neutral postion. 2) I power down, and when I give it additional power, the locomotive is in reverse. 3) When I power down again and back up, the locomotive is in neutral. 4) When I power down again and back up, the locomotive is finally in forward. Is this normal, or should I have it serviced? Any comments would be appreciated.
