To find out whether your child's Thomas & Friends wooden toys, like the red James engine above, are among the 1.5 million targeted for recall: Call RC2 Corp. at (866) 725-4407 or visit the U.S. Consumer Product Safety Commission Web site at www.cpsc.gov for a list and photos of the affected toys.

Two-year-old Tyler Vigna’s favorite Thomas the Tank toy disappeared during naptime Thursday.

His mother, Diane, hopes he doesn’t notice. But she had little choice after hearing the RC2 Corp. and the Consumer Product Safety Commission voluntarily recalled 1.5 million wooden railway vehicles from the Thomas & Friends Wooden Railway product lines.

The recall followed the discovery of lead paint in 26 products – most painted red – made in Chinese factories. The toys affected were manufactured between January 2005 and April 2007.

The recalled products represent about 4 percent of wooden railway units sold domestically, according to the CPSC. Parents were urged to take away the toys, because lead paint is toxic and could lead to significant health problems. No reports of illness or injury have occurred.

“We’re going to be packing up a lot of stuff,” said Adina Morse, a Lawrence mother of two, including a 4-year-old who’s an avid Thomas the Tank fan.

Since her son’s birth in 2003, he has received a toy from the product line for nearly every holiday. Though he is past the chewing phase, she said, the family won’t take a risk with lead paint.

“It’s absolutely a concern,” she said. “Especially with toys made out of a country where there are no checks.”

Patty Davis, spokeswoman for the CPSC, said, “It is our understanding that one of the Chinese factories changed paints in January of 2005.”

Local stores have removed the items from the shelves. For The Toy Store, 936 Mass., the recall affected less than 10 percent of its Thomas the Tank line, according to employee Pete Mapes.

Target carried five of the items that were included in the recall, said Lena Michaud, the store’s spokeswoman. She said customers could bring the toys back to the store.

Davis said parents should keep their toys to request an exchange from RC2 Corp.
