APC Anchor Rail Fastener System Vs KB-65 Rail Fastener System
Jan 20, 2022
The APC anchor intermediate rail fastener created by the Moscow State University of Railway Engineering (MIIT) is one of the non-interlocking elastic fasteners and is intended for use on the seamless track of cargo-stressed lines of mainline railways.
The mass introduction of the APC anchor rail fastening allows, unlike all other types of rail fasteners used on the Russian railways, to solve two main tasks facing the network's track economy for a long time, namely:
- Switch to the sparsely populated technology of the current path content. Dramatically reduce the likelihood of theft of rail lashes of a seamless track (with all the consequences that follow from this), the causes of which are associated with structural deficiencies of fasteners used in Russia, and mass failure of terminal and embedded bolts due to their unsatisfactory content.
- Switch to a low-traffic technology current content path. Dramatically reduce the likelihood of theft of seamless track rails (with all the ensuing consequences), the causes of which are associated with structural shortcomings of the fasteners used in Russia, and the mass failure of terminal and embedded bolts due to their unsatisfactory maintenance.
The main advantages of APC Railfastening in comparison with KB-65 Rail Fastener System

- Ensuring reliable fastening of rail lashes from longitudinal movements without periodic twisting of the fastening elements, in this regard - a significant reduction in operating costs for the current maintenance of the track. Technical and economic calculations carried out using data from the South-Eastern, Moscow and Oktyabrskaya railways showed that the savings in operating costs of more than 100 million rubles per year for every 1000 km of track;
Less elements: it has half as many parts in the fastening unit (9 vs. 21), which provides savings of 16.43 tons of metal per 1 km of travel;
The weight of removable elements is 3.6 times less;
Ensuring a more stable maintenance of the track gauge in width;
Ensuring the alignment of the railway track at a level of up to 25 mm (KB-65 - up to 14 mm);
Due to a significant reduction in the loads in the area of interaction between the anchor and the sleeper, compared with the loads when using embedded bolts in the KB-65 fastening, creep or vibration resistance is sharply reduced, which ensures the service life of the sleeper for more than 50 years;
2.1 times reduction in the labor intensity of work on the assembly of the rail-sleeper grating with the fastening of the APC on the link-assembly base (manual assembly option);
The possibility of fully automated assembly of the rail-sleeper grating through the use of automatic assembly lines operating with a capacity of up to 1000 m of the rail-sleeper grating in an 8-hour work shift . The annual economic effect of the centralized assembly of the reinforced concrete grating with APC fasteners at the Liskin plant "Special Concrete concrete" is 67,500 rubles per kilometer of finished products.
The calculation does not take into account the savings from the reduction of: land plots, industrial, warehouse and household premises, reduction of utility costs, maintenance costs of utility networks, electricity consumption, in addition to reducing the wage fund, the reduction of social security costs, etc. is not taken into account.
The main disadvantage of ZhBR and APC fastenings is the insufficient provision of a stable gauge in curved track sections, especially in steep curves. The reason for this is the poor quality of the polymer fastening elements.
