Full title and description

SN RK 3.03-14-2014 — "Railways" (СН РК 3.03-14-2014 «Железные дороги»). This Kazakhstan national construction standard specifies requirements for the design, construction and operation of railway infrastructure (main tracks, additional tracks, reconstruction and strengthening of existing lines) for the 1520 mm gauge.

Abstract

These construction norms establish functional and operational requirements, performance (working) characteristics and technical rules for railway lines of 1520 mm gauge intended for passenger and freight traffic. They cover track structure, earthworks, drainage, upper and lower track structure elements, and parameters related to axle and linear loads and maximum operating speeds for different train categories.

Scope

This standard applies to the design, construction and operation of new railway lines, additional main tracks (second, third and fourth tracks) and the strengthening or reconstruction of existing public railway lines of 1520 mm gauge. It covers infrastructure designed for axle load on a rail from a four-axle wagon of 245 kN (25 t), a linear load of an eight-axle wagon of 103 kN (10.5 t), and train operating speeds up to: passenger trains — 200 km/h; freight trains — 120 km/h; accelerated freight and refrigerated freight — up to 140 km/h (inclusive).

Key topics and requirements

• Definitions and terminology specific to railway infrastructure (upper and lower track structure, earthworks, ballast, sleepers, etc.).
• Functional requirements for route capacity, alignment, and intended traffic categories (passenger, freight, high-speed parameters).
• Working (performance) characteristics: permissible axle and linear loads, track geometry tolerances and allowable speeds for different train types.
• Design rules for track structure (rails, fastenings, sleepers/plates, ballast), drainage and protection of earthworks.
• Requirements for reconstruction/strengthening of existing lines to meet higher load or speed classes.
• References to related national and intergovernmental normative documents and normative links used by designers.

Typical use and users

Primary users are railway infrastructure designers, civil and track engineers, construction contractors, infrastructure owners/operators, railway planners and regulatory authorities in Kazakhstan. The standard is used when preparing design documentation, tender specifications, construction supervision and technical acceptance of new or reconstructed railway lines within the stated scope.
