I'm not sure that I understand your post.

The switches work well, despite being old? A lot of railroaders would tell you to leave them alone.

Why do they look bad? Do they need to be polished? Are they chipped and/or rusty? Could you make one oval of track using all the old tracks? Or could you make a powered switchyard with them?

You have a lot of potential with those items, so be careful not to ruin them.
