Electrical machinery repair works

Vilnius Locomotive Repair Depot successfully implemented a state-funded project, which was started by the European Union in 2008, titled “Increasing international competitiveness by expanding manufacturing base of Vilnius Locomotive Repair Depot in 2012.It is a unique project, as our company is the only one to perform activities of that kind of nature and complexity, related to the production and maintenance of railway transport. As the project was implemented, the company can now provide electric traction engine maintenance services, repair works, capital repairs, modernization and remotorization services in one place. According to this project, the company has modernized its production process, installed new productive technological line and reconstructed its internal engineering networks. The possibilities of the Depot have expanded, therefore advanced maintenance and modernization services for the traction vehicles can be provided. Since the project, company’s competitiveness has increased, reliability, effectiveness and quality of country’s rail transport has improved and its impact on the environment has decreased.

Results of the implemented project for the reconstruction of electronic machinery repair department during 2008 – 2012 helped to install technological and organizational novelties in the railroad vehicle department: time of the repair works and manual operations has decreased, quality and technical parameters of the services highly improved, defection of the production remained minimum, overall electric machinery repair time was reduced and consequently less power resources are being consumed.
