Corridor

Corridor (Fr. corridor, from Ital. corridore, Med. Lat. corridorium, a “running-place,” from currere, to run), a main passage in a large building, on which various apartments open. In public offices, prisons, workhouses, hospitals, &c., the corridors are usually of severe simplicity; but in mansions and palaces large corridors (galleries) are often adorned with works of art, whence comes the term “picture gallery” applied to many collections. The term “corridor carriage” is applied to the modern style of railway carriage in which a narrow passage connects the separate compartments, the object being to combine a certain degree of privacy for the traveller with access from one compartment to another whilst the train is in motion.
