The RPM-RS-900 was designed for formation remediation and for processing track ballast, and is the longest machine in SPITZKE’s technology park. Its strength lies in its versatility. Formation rehabilitation, ballast cleaning and ballast recycling are all achieved within a single machine complex. The ballast is excavated, recycled, re-laid, compacted and stabilised. The soil is excavated, the new FPL material laid, profiled and compacted. All operations are rail-bound, without blocking the adjacent track. This enables short track possessions and high track availability.
