Ballast and Formation Work

Rail Works › Specific Works › Ballast and Formation Work

Presenter		Project
Location		Date

Ballast is the crushed stone bed that supports the track and distributes train loads to the formation below.
Formation work involves preparing the subgrade, placing capping layers, and building up the track bed.
Ballast handling generates silica dust from crushed granite and basalt, requiring dust control measures.
Tamping machines, ballast regulators, and shoulder cleaning trains operate on live possessions at speed.
Manual ballast work using shovels and forks is extremely physically demanding and causes back injuries.
Walking on loose ballast is unstable; twisted ankles and falls are common, especially carrying tools.
Rail-mounted plant moving during ballast work creates struck-by risks for ground workers on the track.
Possessions provide limited working windows; time pressure increases the risk of shortcuts and rushing.
PTS and specific task competencies are required for all workers involved in ballast and formation tasks.
Network Rail standards and the safe system of work govern all track bed construction and maintenance.

Plant strikes	Rail-mounted tampers and ballast trains move on the track during work, striking workers who lose awareness.
Silica dust	Crushed granite and basalt ballast generates respirable crystalline silica dust during handling and placement.
Musculoskeletal injury	Manual shovelling and raking of heavy ballast in awkward positions causes chronic back and shoulder damage.

Don't

Hold valid PTS and ballast handling competencies before starting track bed work.
Wear RPE when handling dry ballast to control silica dust inhalation.
Maintain awareness of rail-mounted plant movements on the track at all times.
Use mechanical aids for ballast placement and spreading where available.
Wear ankle-support boots with good grip when walking on loose ballast.
Follow the safe system of work and COSS instructions throughout the possession.
Dampen dry ballast to suppress dust generation during handling operations.
Take regular breaks from manual shovelling to prevent back and shoulder injury.
Stay within the defined worksite limits and clear of adjacent live lines.
Brief the team on plant movements, worksite limits, and the possession timing.

DON'T work on or near the track without valid PTS certification.
DON'T handle dry ballast without dust suppression or RPE for silica control.
DON'T stand in the path of approaching rail-mounted plant during ballast work.
DON'T manually shovel ballast for extended periods without rotating the task.
DON'T rush work because the possession window is running short.
DON'T walk on ballast while carrying heavy loads that impair your balance.
DON'T stray beyond the worksite limits onto adjacent live running lines.
DON'T ignore warnings from the COSS or lookout about approaching movements.
DON'T leave tools or materials on the track where they could obstruct trains.
DON'T assume the possession will be extended; plan work within the agreed window.
