On behalf of Infrabel, we worked at multiple locations in Belgium on the high-speed line (HSL). In the summer of 2025, we carried out the second phase of the renewal of Track A on HSL1 (Brussels–French border) and replaced sleepers on HSL2 (Leuven–Liège).
HSL Brussels – French Border
The high-speed line (HSL) between Brussels and the French border is an important European rail corridor for passenger transport. To minimise disruption for travellers and Eurostar (the operator), a phased approach was chosen. In the summer of 2024, we completed the first phase (approx. 18 kilometres from Tourpes to Infrabel Brugelette). Working from south to north, we renewed the track in one direction (permanent-way works). To make this possible, the RU 800 S, a tamping machine and a BDS were deployed.
In the summer of 2025, from 15 August to 1 September, we renewed around 16 kilometres of track between Halle and Enghien, including sleepers and rails. Next to that, we also cleaned the ballast.
In the summer of 2026, we once again began work on this section of the route. Click on this link to read more about the project.
Facts and figures
- Client: Infrabel
- Project duration: 18 days and nights, with 90 technicians working around the clock in three shifts
- Over 26 kilometres of rail installed
- Approx. 26,673 new sleepers
- About 2,400 tonnes of renewed ballast

HSL Leuven – Liège
In addition, on behalf of Strukton Rail Belgium, we replaced sleepers along more than 24 kilometres of HSL2 in the summer of 2025. This is the high-speed line between Leuven and Liège. We deployed our RU 800 S and the 4X tamping machine and replaced approximately 40,877 sleepers.
