Under the contract PKP PLK will receive three 09-3X Dynamic Tamping Express units and a Unimat 09-4×4/4S Dynamic plain line and switch/crossing tamper. The order is part of a Zlotys 250m investment in PKP PLK’s infrastructure maintenance fleet. Last year PKP PLK awarded ZPS, Poland, a Zlotys 125m contract to supply 36 infrastructure maintenance vehicles. A new ballast profiler was also ordered in 2018.
