Jim and Beardog, Thanks for the reply. I may try the gentle washing with dish soap and be careful around the stamping. Thanks also for the compliment. I have been setting this train up under the Christmas tree since I was younger than 10 and my brother did it b4 that for my Uncle Walter. When he passed a long time ago, I inherited it. He was nice enough to give it to me, and I have treasured it since. I keep it on my dresser, and often still run it at Christmas. Take it out off the dresser and put it on the track, and it still runs like a top. Perfect. Over a hundred years in our family! We are very fortunate to have it.
