EXAMPLE OF COUPLING OF RAILWAY RAIL WAGONS
Types of rail couplings
There are different types of train couplings in the world. But in Brazil, the most commonly used models of rail couplings are:
- Coupler by train model Janney
- Coupler rail model Sharfenberg
- Coupler of train cars model BSI Compact
Janney Model Train Hitch
Invented and later patented by the American ELI H. Janney in the year 1873 the model of train coupling known as Janney was first used by the AAR (Association of American Railroads) as the standard iron coupling model.
The Janney model rail coupling is automatic and “mandibular” type, as they are opened and when the coupling comes into contact, such as in a jaw that in this case would be caught one another. Extra cables are required for electrical and pneumatic connections when using this type of shackle hitch, as it does not do it by default.
Talk to our sales team to learn more about the production of this type of coupling and others. We will be happy to evaluate your metalworking project for the production of couplings from the most varied models.

Compact BSI coupling type
First used by the longest subway in 1978, this type of iron coupling was invented and patented by Bergische Stahl Industrie (currently Faiveley Transport).
The movement that occurs between the train wagons, when using this coupling model, occurs in the pivot because the coupling head is integrally part of the coupling, so there is no movement between the couplers when connected.
The BSI Compact coupling type has three 3 divisions:
Top of the BSI Coupling Compact
Connected in the center is the main pipeline air connection block
Central part coupling BSI Compact
The central part represents a mechanical connection block consisting of:
- head of the train hitch
- in the connecting hole of the coupling head of the opposite train
- in the head guide of the coupling of the opposite train
Bottom coupling BSI Compact
Electrical connection block (electric portion) with the cover closed.
Type of coupling Scharfenberg
The German designer Karl Scharfenberg was the one who invented the coupling model today called Scharfenberg. The coupling of this is simpler than that of the competitor Janney because it needs only a touch between the couplings of the wagons so that they are coupled, as well as in the model of mandibular coupling. In addition, the electrical connections in this model of engagement are already standard of the part, which dispenses extra cables. To uncouple the Scharfenberg coupling model just pull a cable belonging to the coupling.
