Rail

Diesel rail is a smaller market than road, but each locomotive runs hard for years. NTROPYX focuses the buyer on fuel, soot, EGR cleanliness and overhaul economics.

Market exposed1.18 Bn L
Recovery signal9% recoverable
Proof context21% residual diesel scope
01 · Diesel recovery

Improve the diesel rail still in service.

Where electrification is incomplete, NTROPYX addresses the remaining fuel burn in locomotives, shunters and service fleets.

02 · Depot compatible

Fit the fuel route operators already use.

The message stays practical: depot fuel, long duty cycles, heavy load and no traction-system redesign.

03 · Maintenance signal

Support lower soot and cleaner circuits.

Cleaner combustion gives rail buyers a clearer link between fuel quality, maintenance drag and operating uptime.

Why NTROPYX here

Structured for rail operators.

Immediate message: fuel efficiency, cleaner combustion, lower waste and a commercial path sized to the sector.

§ 02 · Economic impact

EU27 — 1.18 billion litres of rail diesel. 9% recoverable.

European rail is 79% electric. The remaining 21% — 42 329 TJ burned by diesel locomotives and shunters in 2023 (Eurostat) — is the residual hydrocarbon scope: ~1.18 Bn L. Cleaner combustion compounds maintenance gains on engines that run thousands of hours a year.

European average diesel pump price, taxes included, week of August 31, 2026, published by the European Commission. Average fuel reduction measured on this engine family. Rail diesel consumed per year, before NTROPYX. Derivation: Eurostat [nrg_bal_c] series FC_TRA_RAIL_E / siec O4671XR5220B = 42 329 TJ EU27. Converted at diesel LHV 36 MJ/L → 1.18 Bn L.
