We have a TON of these Thomas toys. The recall is for Thomas the Tank Engine wooden railway cars. They found lead in the paint. The full list is on the links below. It looks like mostly red and yellow colored engines/cars.

I'll have to look into this more. My son doesn't play with them much anymore, but I was saving them for my future grandchildren. (I know I'm weird, but whatever! )
