What is the smallest operating railroad car you’ve ever seen? Have you ever seen a moving train so small that bits of dust on the track can stop it?
Incredibly diminutive trains are coming to the San Diego Model Railroad Museum in Balboa Park! Each car is about two inches long–the size of your finger!
A new Z scale permanent exhibit is being built in the museum and should be completed later his year. As a sign in the museum explains, this cool project is being supported by a grant from The Norris Foundation.
Z scale model trains are so tiny a complete oval layout can fit inside a briefcase. They have a scale ratio of 1:220. They’re even smaller than the N scale trains one can see in the museum’s incredible Pacific Desert Lines layout, which is operated by the San Diego Society of N Scale.
A sample Z scale layout is already on display (above photo). Plans for the not-yet-built layout can also be viewed…
