DB Cargo UK Tests Class 93 Tri-Mode Locomotive on Intermodal Service

Why It Matters

The trial proves that flexible, low‑emission tri‑mode locomotives can meet heavy‑haul freight demands, accelerating the rail sector’s shift toward greener operations.

Key Takeaways

• Class 93 tri‑mode hauled 1,500‑ton intermodal train.
• Four power modes include electric, diesel, hybrid, battery‑only.
• Tests conducted with Rail Operations Group, Network Rail, ASLEF.
• Performance meets DB Cargo’s future fleet investment criteria.
• Supports UK rail freight decarbonisation strategy.

Pulse Analysis

The UK freight rail network faces mounting pressure to cut emissions while maintaining capacity on mixed electrified and diesel routes. Tri‑mode locomotives like the Class 93 offer a pragmatic bridge, combining 4 MW electric power, a 900 kW Stage V diesel engine and high‑density lithium‑titanate batteries. This flexibility enables operators to run heavy intermodal trains under overhead lines, switch seamlessly to diesel on non‑electrified sections, and even operate emission‑free in urban terminals, aligning with the government’s net‑zero rail targets.

During the March 10 trial, locomotive 93006 hauled a 1,500‑ton train for Peel Ports from Merseyside to Glasgow and back, demonstrating reliable starts on steep gradients and consistent traction across all four modes. The involvement of Rail Operations Group, Network Rail and the ASLEF mechanics’ union provided a comprehensive assessment of performance, maintenance needs and network compatibility. DB Cargo’s COO, Mark Sargant, cited the results as a key data point in the company’s ongoing fleet‑investment review, suggesting that the Class 93 could become a cornerstone of its modernised rolling stock portfolio.

If the Class 93 scales beyond pilot runs, it could reshape procurement strategies across the UK rail freight sector. Operators seeking to future‑proof assets against expanding electrification corridors and stricter emissions legislation may view tri‑mode technology as a cost‑effective alternative to full diesel replacement or costly full electrification. Competitors such as Alstom and Siemens are also developing hybrid solutions, intensifying market competition. Continued demonstrations and real‑world data will determine whether tri‑mode locomotives become the new standard for versatile, sustainable freight haulage.
