With a length of almost 200 metres, the PM 200-2R formation rehabilitation machine is the largest machine ever to be built in a Plasser & Theurer workshop.
The constructional achievement lies in part in the organisation of the many different transport tasks to be performed within the machine: all conveyor lines are clearly laid out and kept as short as possible. The machine is operated by the German firm Eurailpool who gained extensive experience previously with the rehabilitation machines PM 200-1 and AHM 800 R.
In August 2002 the PM 200-2 R introduced a new era of rail-mounted substructure improvement. This is the only machine that recycles the excavated ballast in the machine and additionally washes the ballast with high-pressure to release the cohesive particles on the ballast virtually 100%. The quality and quantity of the reconditioning thus reaches a previously unknown standard.
