Protecting rail infrastructure without disrupting operations

Refurbishing the overhead line structures of a strategic railway station on the Paris–Lyon main line

As part of the accessibility programme for persons with reduced mobility (PRM) at Mâcon-Ville railway station, GTA Coatings recoated and provided long-lasting protection for the overhead line supports and gantries on the platforms.

Located on the Paris–Lyon main line at kilometre point 439, the station comprises a passenger building and three operational platforms serving several tracks. The works therefore had to be carried out in a particularly constrained railway environment, directly above and adjacent to live tracks.

The works combined manual surface preparation, treatment of legacy coatings, encapsulation of sound existing layers, application of a corrosion protection system and a signal grey RAL 7042 finish. Interventions took place at night, during temporary track possessions and with the overhead line equipment (OLE) isolated.

The possible presence of lead in the legacy coatings required a specific procedure: protection of the work areas, waste recovery, suitable personal protective equipment (PPE) and a decontamination unit. GTA Coatings thus refurbished the structures in compliance with railway, environmental and occupational health requirements.

Performance & technical know-how

Corrosion protection of overhead line structures

Manual surface preparation by degreasing, brushing and systematic scraping.
PST2 preparation grade to ISO 8501–2.
Treatment of bare areas with WIEKORANT-A2B-DKX-Grund primer.
Encapsulation of sound existing coatings.
Application of a GEHOTEX-W78B topcoat on all structures.
Signal grey RAL 7042 finish.
Treatment of masts, beams, brackets, anchor beams, stays, tensioning devices and associated fittings.

These works restored the protection of the metal equipment and extended its service life in a highly exposed railway environment.

Rail works under tight constraints

Night-time works during temporary track possessions, with the OLE isolated.
Five nights a week with a team of six.
Access to the structures using road-rail aerial platforms.
Staff trained in railway site safety rules and in collision and electrical risks.
Tarpaulins, geotextiles and protection installed on platforms, tracks and ballast.
Specific handling of waste potentially containing lead: marking out, vacuuming, packaging and removal.
Suitable PPE and a decontamination airlock.
Quality monitoring through humidity readings, work sheets, a quality assurance plan and FROSIO inspections.

The site organisation reconciled team safety, lead hazard control, application quality and railway operating constraints.
