Due to amendments to the regulations governing railway traffic, the rules for calculating the braking weight of railway vehicles in operating documents such as KPH (Brake Test Card) and R7 have changed. In response to these changes, the mRails and RCMS systems have been fully adapted to the new legal requirements. This means that both systems now enable the recording of braking weight depending on the brake setting of the railway vehicle, as well as the automatic use of this data when preparing travel documentation.
The changes result from amendments to the regulations of the Minister of Infrastructure and updates to the Ie-1 instructions (Train Traffic), which clarified the method of determining train braking parameters. The aim of the regulations is to provide a more realistic representation of the braking force of railway vehicles, especially in the case of vehicles equipped with block brakes.
Braking mass and brake setting
One of the most important changes is linking the braking mass of a railway vehicle to the brake setting. In practice, this means that a single vehicle can have several braking mass values assigned to different brake modes, such as P, G, or R settings.
Until now, in many cases, a single braking mass value was used for a vehicle, regardless of the configuration of the braking system. The new regulations introduce a more precise approach, in which the braking mass must correspond to the actual brake setting used when driving the train.
This value has a direct impact on traffic safety, as it is used to determine the braking capacity of the train and for calculations related to train operation.
Showing the braking mass in operating documents
In accordance with applicable regulations, documents such as R7 and the Brake Test Card show the total braking weight of the entire train. This includes both the traction vehicle and all cars in the train.
The value of this mass is influenced, among other things, by the selected traction vehicle brake setting, the technical condition of the cars, and their load. In practice, this means that braking parameters may vary depending on the configuration of the train and operating conditions.
Automatic selection of braking mass in systems
The new regulations require rail carriers to store information in their IT systems about the braking weight assigned to individual brake settings for each rail vehicle. This data is entered into the vehicle file by the operations department.
The mRails and RCMS systems use this information when preparing travel documentation. When the user selects the brake setting, the system automatically retrieves the appropriate braking weight value from the file and includes it in the operating documents. This ensures that the data shown in the documents complies with applicable regulations and the actual configuration of the railway vehicle.
The significance of changes for railway traffic safety
Significance of changes for railway traffic safety Linking the braking mass to the brake setting allows for a more precise determination of the braking capacity of a train. As a result, the operating parameters better reflect the actual operating conditions of railway vehicles.
Adapting the mRails and RCMS systems to the new regulations enables the automation of the braking mass calculation process and ensures that documentation complies with current regulations. As a result, these changes increase the safety of railway traffic and reduce the risk of errors in operational documentation.
