Network Rail has initiated the early stages of ETCS equipment fitment across freight locomotives, starting with GB Railfreight’s Class 66 locomotive no. 66 784.
This is the first vehicle to receive onboard ETCS technology beyond the 'first in class' prototypes. The work is part of the East Coast Digital Programme (ECDP), a £1.4 billion project (€1.65 billion) to implement digital in-cab signalling across sections of the East Coast Main Line. Under ECDP, legacy signalling infrastructure is being replaced by continuous digital communication systems within locomotive cabs.
The freight component of this transition presents specific technical and integration challenges, particularly for locomotives built several decades ago. Siemens Mobility is supplying the onboard units under a contract with Network Rail, providing its Trainguard 200 solution for Class 66 locomotives. This fleet forms the core of the UK’s freight operations.
Network Rail, Siemens, and freight operators have worked jointly to define a baseline integration approach for Class 66. The installation on 66 784 is the first of eight locomotives scheduled for early fitment, while system design refinement continues ahead of final approval for operational use (APIS).
The current activity builds on previously completed 'first in class' fitments involving units from DB Cargo and Freightliner. Contracts remain in place for continued rollout through 2025 and 2026, with Siemens also engaged in installation work for additional DB Cargo locomotives and units prepared by EMD.
The National Freight ETCS Programme is expected to include more than 600 locomotives across the network.
