České dráhy is expanding its tests with biogenic fuels: Three RegioFox diesel multiple units from the Rakovník depot will in future run on fully biogenic HVO on routes in Central Bohemia. Following a 20-percent HVO trial since April 2025, the company is taking a further step towards reducing local emissions on non-electrified lines.
Quick overview
This news is particularly relevant for rail travelers because it may have concrete effects on planning, connections or infrastructure. The focus is on Ceskedrahy, Regiofox, Hvo, biofuel, alternative fuels, Central Bohemia, rail transport and decarbonization. The key points are summarized compactly below.
Key points
- Three RegioFox multiple units built by PESA Bydgoszcz (with Rolls-Royce engines) will in future be operated with pure HVO fuel.
- HVO (Hydrotreated Vegetable Oil) can be produced from vegetable oils, used cooking oils or fat waste.
- Depending on the feedstock, GHG savings of 60–65% (vegetable oil) up to 90–95% (used cooking oils) compared with fossil diesel are possible, according to České dráhy.
- This followed a trial running since April 2025 with 20% HVO on the Rakovník–Beroun and Beroun–Prague routes.
- The multiple units and fuel blends had previously been tested at the Velim railway test center.
What this means for travelers
For travelers, it is worth taking a close look at the time period, route and booking conditions. The key question is whether the news already triggers concrete timetable changes or initially describes a political or strategic development.
Context
Background: Large parts of the Czech rail network are not electrified. According to Deputy CEO Jiří Ješeta, combustion engines will likely still be needed there for several decades. In engines approved for the purpose, HVO can be used pure or as a blend and is largely chemically compatible with fossil diesel. The project was launched in 2024.
What to watch now
- Only check concrete timetable or service notices once travel dates are fixed.
- When traveling internationally, plan connection times more generously.
- Watch the source and operator information in case schedules are still provisional.
