 The exterior is decorated with Socialist Realist paintings.Music emanates from the wagon's darkened interior, and, upon crossing the threshold, the viewer finds a mural depicting an idyllic Soviet city, peaceful, harmonious, and prosperous, with a blue sky filled not with clouds but apparently with an airshow of biplanes, hot-air balloons, and zeppelins.Benches are placed opposite the mural, allowing the viewer to rest and take in the music and imaginary scenery.
