1991 - commissioned section of track with rail-sleeper grid with anchor bonding (APC)
2-kilometer-long test section was created on the path distance Eletskaya South Eastern Railway. Its operation for 10 years has demonstrated high reliability anchor-rail fastening.
The use of concrete sleepers spring staple ARS-4 is a completely new advanced technology instead of using loops, with 1KB klemno-bolt bonding.
The transition to this high-tech construction bond is many times increases the performance of the way with substantial economic efficiency - at every kilometer of ways to save at least 15 tons of metal. Also significantly increases the safety and speed of trains due to the guaranteed reliability of the spring attachment rail to the tie.
Serial introduction of a new design of the APC during overhaul of the way started in 2003. Liski (the largest railway junction in South-East highway) at the "Spetszhelezobeton" was first started production of a new type of sleepers.
In 2006 came into operation the first in the world high-tech production line automated assembly track rail-sleeper grid staple ARS-4. When operating at full capacity automated line capable of delivering 25 thousand per month. Sleepers equipped with APC. During the year it will provide overhaul 667 kilometers.
