A heavyweight observation at the Illinois Railway Museum An observation car (often abbreviated to simply observation) is a type of railroad passenger car. It is almost always operated as the last car in a passenger train.
Configuration
An observation's interior could include features of a coach, lounge, diner, or sleeper. The main spotting feature was at the tail end of the car - the walls of the car usually were curved together to form a large U shape, and larger windows were installed all around the end of the car. On older cars, the rear end of the car consisted of a large canopied porch-like area
The interior of a lightweight observation At this end of the car, there was almost always a lounge where passengers could enjoy the view as they watch the track recede into the distance.
History
When passenger trains were still the preferred mode of intercity transportation in America, observations often were used by those campaigning for public office, especially for the Presidency of the United States. The candidate's train would pull into town and stop with the observation end at the station, then the candidate would appear on the observation's platform to deliver his "stump speech". The observation platform made a perfect temporary stage for just such an event.
Industrial design
While the cars manufactured by companies such as Pullman-Standard conformed to somewhat standard designs, some railroads created their own distinctive designs for ovservation ends. For example, the Milwaukee Road's passenger trains were often rounded out with either a Skytop Lounge or a Beavertail observation. The Milwaukee's observations were easily recognizable as the observation end of the cars were not only rounded, but also slanted toward the front of the car, often with windows extending up from the normal window height to the roofline.
The Western Pacific Railroad built combination dome-observation cars for use on the California Zephyr. The railroad touted this combination car type as "the best of both worlds" in passenger amenities.
