Abstract (Swedish)
Electrification of regional railway systems constitutes a promising strategy for reducing greenhouse gas (GHG) emissions and improving air quality in the transportation sector. While full electrification via overhead line equipment (OLE) is technically viable for high-density corridors, it is often not economically justified on low-traffic routes due to high infrastructure costs relative to usage levels. Battery-electric trains (BETs) have therefore emerged as a potentially cost-effective and operationally flexible alternative. However, the reliance on large onboard battery systems—required to span extended unelectrified segments—brings about several drawbacks, including significant capital and lifecycle costs, and notable environmental...

Electrification of regional railway systems constitutes a promising strategy for reducing greenhouse gas (GHG) emissions and improving air quality in the transportation sector. While full electrification via overhead line equipment (OLE) is technically viable for high-density corridors, it is often not economically justified on low-traffic routes due to high infrastructure costs relative to usage levels. Battery-electric trains (BETs) have therefore emerged as a potentially cost-effective and operationally flexible alternative. However, the reliance on large onboard battery systems—required to span extended unelectrified segments—brings about several drawbacks, including significant capital and lifecycle costs, and notable environmental impact related to battery manufacturing and charging facilities. To address these challenges, this study proposes a shared charging infrastructure model for both rail and road vehicles, combining static and dynamic charging strategies. Static charging refers to energy transfer while the train is stationary, usually at stations, and can be implemented with relatively low capital investment. Dynamic charging involves supplying energy during motion via Electric Road System (ERS) technologies. Solutions developed by companies such as Alstom [1],© 2025 by the authors.
