The "Wooden Railway Troublesome Truck and Crates" and "Troublesome Truck and Paint" have been recalled by Fisher Price due to choking and magnet ingestion hazards.

The manufacturer says the small plastic piece containing a high-powered magnet that connects one train to another can detach or become loose, posing choking and magnet ingestion hazards.
