Elimination of track settlements and defects

About the Company

Since 2010, Prombudkoliya has been carrying out elimination of track settlements and defects on mainline, industrial, and station railway sections. We provide comprehensive restoration of track profile, elimination of deformations and defects of the railway superstructure, extending its service life and improving train traffic safety.

All works are performed in accordance with Ukrzaliznytsia regulations and DBN standards, using modern track machinery, geodetic control, and certified materials.

Causes of Track Settlements and Defects

Track settlements and defects occur due to ballast wear, loss of subgrade compaction, uneven rolling stock loads, climatic factors, and insufficient drainage. Without timely repair, these deformations lead to track geometry violations, increased vibration, and emergency situations.

Main Types of Defect Elimination Works

Track Diagnostics and Inspection

Visual and instrumental inspections are carried out to identify settlement zones, misalignments, and damage to sleepers or rails. Geodetic instruments, flaw detectors, and track measurement systems are used.

Elimination of Subgrade Settlements

Removal of weakened soil, restoration of the sub-ballast layer, base compaction, and construction of drainage channels are performed. Where required, geotextiles and high-strength crushed stone are used.

Track Alignment and Sleeper Tamping

Mechanized alignment and tamping of sleepers are carried out to restore the design track geometry. VPO-3000, VPRS machines, and ballast regulators are used. Works are performed with high precision based on geodetic data.

Ballast Layer Restoration

Cleaning or replacement of contaminated ballast, layer-by-layer compaction of new material, formation of the ballast prism, and profile leveling are performed. This ensures track stability and uniform load distribution.

Repair of Sleeper and Rail Defects

Damaged sleepers, joint bars, bolts, and fastening elements are replaced. Where necessary, rail welding or partial rail replacement is carried out. All components are checked for proper seating and stability.

Track Stabilization

After defect elimination, track stabilization is performed to fix the new position and prevent repeated settlements. Dynamic stabilizers and ballast vibration compaction are applied.

Stages of Work Execution

1. Track condition diagnostics and defect identification
2. Site preparation and material supply
3. Elimination of settlements and subgrade deformations
4. Track alignment, tamping, and stabilization
5. Geometry control and documentation of results

Completed Project Examples

Settlement Elimination on the Lviv – Mukachevo Section (2023)

Alignment and stabilization of a 6 km track section, drainage restoration, and ballast replacement were performed. Works were completed within 14 days without stopping train traffic.

Settlement Repair on an Industrial Spur Line (Kryvyi Rih, 2022)

Subgrade settlement elimination, sleeper tamping, and track stabilization were carried out. The result was restoration of the design profile and smooth rolling stock operation.

Local Track Defect Elimination at a Station (Poltava Region, 2021)

Sleepers were replaced, track misalignments corrected, and the ballast layer restored. Works were completed within 5 days followed by track geometry control.

Frequently Asked Questions

How can track settlement be identified?

Settlements are indicated by increased vibration, track gauge distortion, uneven train movement, and visible ballast deformation. Instrumental inspection is required for accurate assessment.

Can settlements be eliminated without dismantling the rails?

Yes, works are performed mechanized without removing the rail–sleeper grid, with minimal traffic restrictions.

What is the service life of the track after settlement elimination?

After alignment and stabilization, the track service life is extended by 8–12 years with regular technical maintenance.
