The museum's centerpiece is a 14.4-meter model railway diorama at 1:87 scale, where night trains, narrow-gauge steamers and freight trains start up on their own several times a day and run through miniature mountains, tunnels and stations. Other rooms hold hand-built 1:20 locomotive models, an 1869 Morse telegraph and engineer Anghel Saligny's desk, reached through a short tunnel. Steam locomotives, including the 1869 Călugăreni, stand in the entrance courtyard.
