Purpose: To analyse and identify the advantages and disadvantages of rail transportation operations based on a review of existing methods; to determine the most promising transportation method for further development. To demonstrate the possibility of using the existing flat cars with improved functionality without modernization. To develop a re-usable rail fastener unit (hereafter referred to as RFU) and to carry out calculations and tests on a 13-6903 standard fitting platform model. To ensure that the by means of RFU doesn't exceed the load from the containers. Methods: Development and testing of the RFU and fitting platform in accordance with GOST 33211— 2014, “Specifications for placing and securing freight rail wagons and containers” No. CM-943, “Specifications for placing and securing of cargo” (Annex 3 to the Agreement on International Carriage of Goods by Rail). Results: A promising method for the transportation of 25-m long rails that does not require any special railway vehicles has been selected and validated. An RFU has been developed and its basic parameters have been confirmed based on the results of tests and trial operation. A possibility of using container flat wagons for rails transportation has been demonstrated. The load has been securely fastened and transport safety has been ensured. The use of disposable fasteners has been avoided. The possibility of transporting an empty RFU by any means of transport was demonstrated, as was the convenience of compact stacking and storage. The simplicity of the design (without the use of technically sophisticated and expensive components), the interchangeability of the RFU components and the ease of repair and replacement of individual elements have been demonstrated. Practical significance: The use of the RFU takes the handling of 25m rails and long products to a whole new level.
