Located on the outskirts of the city, the Transportation Museum has exhibits and interactive games about planes, trains, ships, and cars of the past, present, and future — and a transit nerd's treasure trove of details about the history and model numbers of Hiroshima's streetcars. (Tram #654, which remained in service after the atomic blast, is on display.) Outside, behind the museum, there is a track with odd bicycles to ride. It's great fun for children.
