Are toy trains safe, or is lead a concern?

Thomas trains were recalled in 2007 due to high amounts of lead, and in a California Watch article (where the photo at left comes from), a dad tests his son's Thomas trains for lead. Fortunately, the trains all tested to be safe -- although they did have trace amounts of lead in the paint.

It's a pretty interesting read if you've ever wondered how experts test for lead or if you're interested in toy safety in general.
