Efficiency using electric traction in railway transport in the Slovak Republic

Nowadays, the European Union emphasizes reducing greenhouse gas emissions. Reducing greenhouse gas emissions is possible in many ways. The support for reducing greenhouse gas emissions can be provided by measures, recommendations, or by making new legislation. On the railway transport, it is possible to electrify the railway network. However, every railway line is not possible to electrify. On these railway lines, the operator can use vehicles on alternative drives. In the Slovak Republic, it is possible to find railway lines where diesel vehicles are used on electrified railway lines. This paper is focused on possible reasons and measures to reduce these cases.
