“BRIK”

“BRIK” – Research and Development in the Railway Infrastructure” is a support programme for research and development works in the field of railway infrastructure organised by the National Centre for Research and Development and PKP Polskie Linie Kolejowe SA. Within the framework of the BRIK programme, Budimex SA is involved in two R&D projects – InRaVis and InRaNos.

The InRaNos project is implemented jointly by NCBiR, PKP PLK SA, the Consortium: Budimex SA, Instytut Ochrony Środowiska – Państwowy Instytut Badawczy (Environmental Protection Institute – National Research Institute), Warsaw University of Technology and TINES Investment Sp. z o.o. The project concerns the development of the prototypes of devices which are installed in the track superstructure to reduce vibrations and noise from rail traffic – rail and track silencers. The InRaNos project is implemented jointly by NCBiR, PKP PLK SA, the Consortium: Budimex SA, Instytut Kolejnictwa (Railway Institute), Instytut Ochrony Środowiska – Państwowy Instytut Badawczy (Environmental Protection Institute – National Research Institute), Warsaw University of Technology and TINES Investment Sp. z o.o. This project aims at the development of innovative solutions within the scope of protection of people and buildings from rail traffic vibrations. As part of the works, four products intended for ballast (sub-ballast vibroinsulation mats and sub-sleeper pads) and non-ballast (sub-slab vibroinsulation mats and system of block rail supports in the cover) structures of track superstructure are to be developed. The role of Budimex in BRIK projects is to install instruments in the railway track on test sections and to cooperate in the development of guidelines for their assembly, assessment of effectiveness and scope of application. Thanks to these solutions, people and buildings will be better protected from noise and vibration. Developed devices and conducted tests may affect the popularisation of these methods in Poland. Numerical simulations and prediction models for efficiency of the devices will make a significant contribution for industry and science, constituting the starting point for the development of further solutions. Laboratory and field testing will allow the assessment of the effectiveness of solutions and to develop guidelines for their use in the railway infrastructure.
