and the 600V DC (trams). These devices constitute part of the state-of-the-art traction stations equipment constructed on the basis of the so-called 'distributed intelligence' utilizing the CAN-BUS type of the computer buses. Our devices have been installed in 54 modern PKP (Polish State Railways) traction sub-stations and in a couple of tram sub-stations.

Over 140 PKP section cabins and over 100 PKP traction sub-stations have been equipped with a system developed by NEEL: it is EUU type electronic dependencies system, that has replaced previously used central-type devices.

In years 1997-2006 NEEL developed and installed the heating and air-conditioning testing system for MSOW-type passenger carriages stationed at three PKP rail terminals: Przemyśl-Bakończyce, Szczecin-Zaleskie Łęgi, Częstochowa, Warszawa-Grochów. The system enables testing of the heating and air-conditioning systems, current measurements, defect localization, as well as preliminary warm-up of carriages waiting for the connection to a locomotive.

The production offer contains also the absolute novelty on a world scale - animal deterring device "UOZ-1" designed for high-speed railway tracks. These devices were installed on the railway tracks of the E20 railway line between Minsk Mazowiecki and Siedlce during its modernization in years 2003-2004. Next applications were installed at the E65 line Warszawa – Gdańsk and at the E30 line. In November 2012 the system UOZ-1 was installed on two sections of the Russian Railways RZD: Moscow - St. Petersburg and St. Petersburg - Helsinki.

We have a Quality Management System approved by the organization ISOQAR, compliant with ISO 9001:2008.

In 2016 NEEL became a signatory of the Declaration on the development of a culture of safety in railway transport of the Polish Office of the Rail Transport.
