Goods wagon

Goods wagons[1] (US: freight cars) are railway wagons that are used for the transportation of goods (freight).

Development

At the beginning of the railway era, the vast majority of goods wagons were four-wheeled vehicles of simple construction. These were almost exclusively small covered wagons, open wagons with side-boards, as well as flat wagons with and without stakes used. But over the course of time an increasing number of specialised wagons were developed.

Special wagons for specific purposes or wagons with special features were already being introduced around 1850 by private companies. Amongst these were tank wagons and numerous refrigerated vans. In countries like Germany, wagon hire firms procured large numbers of these wagons and hired them to the end users.

In the early days of the railway goods trains still ran at top speeds of about 20 mph (32 km/h). However the introduction of through brakes using air pipes (such as the Kunze-Knorr brakes in Germany) from the 1920s enabled higher speeds to be safely achieved. Modern goods wagons are authorised for speeds up to around 75 mph (121 km/h) and in certain countries wagons are increasingly equipped with GPS receivers and transponders which provide location monitoring as required. The Deutsche Bahn (DB) even has goods wagons cleared for high-speed rail travel at up to 100 mph (160 km/h). Because the braking distance of fast goods trains is longer than the separation between distant and home signals (as are Express Passenger trains), they may only run at high speeds of 150 mph (240 km/h) with locos on routes with early signalling systems in the driver’s cab (LZB, FZB and ETCS).

German wagon history

In Europe the first agreements were struck very early on between the national state railways (Länderbahnen) and private companies for the mutual use of each other’s goods wagons. And around 1850 the Union of German Railway Administrations (Verein Deutscher Eisenbahnverwaltungen) drew up regulations for the standardisation of dimensions and fittings. The formation of the Prussian State Railway Union in 1881 encouraged the emergence of wagon classes built to standard norms.

One further European milestone was the formation of the German State Railway Wagon Association on 1 April 1909. With the participation of all the German state railways, it created a common pool of goods wagons, which by the end of 1911 had no less than 560,000 wagons. In addition, they all had standardised inscriptions and red-brown livery. In order to standardise future procurements a total of 11 wagon classes were defined (Sheet nos. A1 to A11). These wagons of the so-called standard class (Verbandsbauart) and subsequent developments from them (the Austauschbauart class with interchangeable parts) dominated goods traffic in Germany up to the Second World War and had a significant impact in many other countries which acquired these wagons either through war reparations or simply because they were left behind by the Germans after the two world wars.

From 1939, wagons were developed primarily from a military point of view and were known as wartime classes (Kriegsbauart). After the war, in East Germany, some pre-war goods wagon classes were given a new lease of life as ‘reconstructed goods wagons’ (Reko-Güterwagen) and continued for several more decades in service.

Since the foundation of the Union of Private Goods Wagon Companies (Vereinigung der Privatgüterwagen-Interessenten (VPI)) in 1921 the interests of private transport organisations in Germany (including wagon hire firms, goods wagon builders and repair firms, owners of private sidings) has been represented jointly. The Union has around 100 members, who own 50,000 goods wagons. In 2007 they transported 361,000,000 t (355,298,556 long tons; 397,934,383 short tons) of goods.[2] Other countries have similar organisations.

European wagon history

Since 1922 the agreement for the mutual use of goods wagons in international traffic (RIV) has regulated the exchange of goods wagons in Europe and the Near East. In addition, international goods wagon fleets were created in 1953 in Western Europe with the Europ-Verband and in 1964 in Eastern Europe with the Common Goods Wagon Park (OPW). During the second half of the 20th century, national goods wagon classes in Europe were increasingly replaced by Union internationale des chemins de fer (UIC) standard wagons. Since 1964, all goods wagons in Germany, for example, have to be classified using the UIC goods wagon classification system.

Types of goods wagon

The numerous types of goods wagon are categorised here based on their main design features and in accordance with the international UIC classification system:

Goods wagons for special purposes include:

Railway post vans (Mobile post offices) are not counted as goods wagons.

The UIC’s instructions were sometimes interpreted differently by the various railway administrations, so that it could happen that almost identical wagons were grouped into different classes. In addition wagons had occasionally to be reclassified after slight modifications. For example, an E Class wagon can become an F Class simply through welding on a door.
