I have a set of some heavy aluminum norfolk western passenger cars that lionel produced. They are not the silhouette ones rather they are lighted with people in them. I really like them but would like to make them more realistic with diaphragms on them. Has anyone ever retrofitted yours? If so where did you get the parts and how did you affix them? I took a picture of the back of the baggage car. I will be in York if anyone knows if the parts available there.
Thanks.
