Das Rollgeräusch von Güterwagen ist die dominierende Schallquelle im Schienenverkehr. Durch den Einsatz von Verbundstoff-Bremsklotzsohlen anstatt von Grauguss-Bremsklotzsohlen wird das Rad weniger aufgeraut und das Rollgeräusch um ca. 10 dB reduziert – für das menschliche Ohr bedeutet dies etwa eine Halbierung des Lärms. Eine Reduktion des Rollgeräuschs der Güterwagenflotte führt zu einer flächendeckenden Lärmminderung entlang aller von Schienengüterverkehrslärm betroffenen Strecken. Anlässlich des ab dem 13.12.2020 wirksam werdenden Verbots des Betriebs lauter Güterwagen auf dem deutschen Schienennetz [1] wird in diesem Artikel der Fortschritt der Umrüstung der Bremsklotzsohlen seit der Zulassung der Verbundstoff-Bremsklotzsohlen im Schienengüterverkehr betrachtet. Die Maßnahmen zur Migration der Technologie in den Markt werden beschrieben. Ergebnisse der Evaluierung des Standes der Umrüstung wie auch Umrüstzahlen auf Basis des nationalen Fahrzeugregisters sowie erste Erkenntnisse aus dem vom BMVI initiierten und vom Eisenbahn-Bundesamt durchgeführten Lärm-Monitoring zur Entwicklung der Schallemissionen von Güterwagen werden präsentiert.   Summary The rolling noise of freight wagons is the dominant noise source in rail traffic. By using composite brake blocks instead of cast iron brake blocks, the wheel is roughened less and the rolling noise is reduced by about 10 dB. A reduction of the rolling noise of freight wagons leads to a comprehensive noise reduction along all lines affected by rail freight traffic noise. On the occasion of the ban on the operation of noisy freight wagons on the German rail network [1], which will come into effect from 13.12.2020, this article examines the progress made in retrofitting of brake blocks since the approval of composite brake blocks in rail freight traffic. The measures to migrate the technology to the market are described. A result of the evaluation of the status of retrofitting as well as retrofitting figures based on the national vehicle register and first results of the noise monitoring initiated by the BMVI and carried out by the Federal Railway Authority on the development of noise emissions from freight wagons are presented.

Since the economic deregulation of freight transport operations internationally, it has been necessary to have a workable knowledge and an understanding of the types of freight wagons that can help to be instrumental in the efficient and effective market participation of rail technology in the freight transport market. The article identifies and describes the most commonly used rail freight wagons for commercial purposes internationally. The investigation has indicated that subsequent to the economic deregulation of freight transport, there are nine rail wagon types manufactured and commonly used internationally. They are: (1) covered wagon/van; (2) refrigerated wagon/van; (3) flat wagon; (4) tank wagon; (5) container wagon; (6) open wagon; (7) hopper wagon; (8) side stanchion and centre partition wagon; and (9) motorcar wagon. The study revealed that the following three factors mainly dictate wagon design: (1) characteristics of the freight to be transported; (2) physical railway characteristics; and (3) the type of freight terminals and handling equipment necessary to efficiently and effectively accommodate and support rail freight transport.

The railway is the fundamental means of transport, especially for freight. It has a substantial contribution to the sustainable economy of the country and the region at large. However, some factors have been affecting the performance of rail operations; especially for freight, to the extent of reducing the modal share from rail to roads. This has been resulting in high road maintenance costs and underutilization of the available capacity in the railway. This research has studied the factors affecting the Tanzanian railway network in the performance of rail freight operations. The focus was on the corridor from Dar es Salaam to Isaka because it serves most of the landlocked countries such as Uganda, Burundi, Rwanda, and Eastern DRC. The study used the Performance Measurement theory with the Balanced Scorecard model. Data analysis was done by the Linear Regression statistical method with the aid of SPSS version 20. The results of the study show that derailments, washouts, and rail freight wagons maintenance capacity directly affect the performance of rail freight operations. TRC, therefore, needs to strategize measures for ensuring that derailments and washouts are very much reduced. A plan for quick recovery must be in place in case a derailment or washout happens. Also, TRC should enhance its capacity for maintaining the rail freight wagons to ensure its optimal availability. Railway should be viewed as a potential area for investment because it supports the growth of other sectors as well. If constraints are minimized in the railway system; the performance of rail freight operation will be high and many customers will be attracted to use the railway as a preferred mode of transport, hence, the modal share to the railway will increase.

Rail transport is a very important type of transport. Due to its environmentally friendly nature it is necessary to dedication him considerable attention. The article stated the need for the implementation of innovative solutions for wagons. This article presents precondition to increase market share of rail freight. Considerations that must be met by modern rail transport were presented in details. The main focus was on provide assumptions to implement innovative wagons and their areas of influence.
