The Scottsdale Railroad Museum will debut its new exhibit this week as it celebrates the city’s annual Railfair, which highlights vintage railroad displays and equipment.

As part of the Arizona Capitol Museum’s rotating exhibit, visitors will be able to view the inside of the Arizona Merci Car during the Railfair for the first time since the display began in 1989, according to a press release.

The Railfair will take place Oct. 7-8. The Merci Car exhibit will be featured as part of the Scottsdale Railroad Museum, which has undergone recent renovations to prepare for the new display.

The Merci Car dates back to after World War II when the residents of France filled 49 railcars with donated items as a thank-you for America’s support during the war. A car was delivered to each state in the U.S.

The Merci Car exhibit will feature personal items from France’s residents, including toys, books, clothing and thank-you notes to the U.S., the release said.

The Railfair will feature model trains, vintage railroad equipment displays and special presentations on the railroad and Arizona’s history.

The exhibit admission is free during the Railfair and is $2 for those age 13 and older. Children under 12 with a paying adult are admitted free.
