With around 450 participants each, and strong international participation, the dcrps conferences in 2020, 2022 and 2024 were extremely successful. Right away they were the largest of their kind. It is therefore obvious that the fourth dcrps conference should be held at the turn of the two years and alternate with the sister event acrps. The forth dcrps is scheduled for 12/13 March 2026.

De-carbonization, energy efficiency, increased performance, digitization - these are just a few buzzwords that currently dominate the railway industry and that also apply to DC electric traction power supply systems. The dcrps 2026 will deal with all DC railways with a nominal voltage of 600 V to 3 kV, both urban railways (trams, underground and suburban railways, trolleybuses) and DC long-distance railways. Other topics include interfaces to the charging infrastructure for electric buses and electrified roads.

The conference is aimed at

• Operators of DC railways and public transport systems
• Railway industry
• Engineering companies and consultants
• Certification companies
• Authorities and associations

Releated to the buzzwords above, topics of the conference will be

• Rail power supply
• (supply, conversion, distribution and operation)
• Contact lines (overhead contact lines and third rail)
• Energy efficiency
• Earthing and the return circuit, EMC, stray current protection
• SCADA systems including cyber security
• Interaction rail power supply/vehicles
• Interaction between AC and DC railways
• Regulations
• Auxiliaries fed by DC traction system
