walkerwarren associates limited.


Following the successful completion of N I Railways purchase of 23 x 3 car Class 3000 DMUs, rail consultancies Interfleet Technology and walkerwarren associates have once again teamed with N I Railways to assist in their acquisition of a further fleet of 20 x 3 car DMUs, dubbed the “Class 4000”.

The proven collaboration of Interfleet Technology and walkerwarren will provide commercial and technical assistance to NI Railways for all stages of the vehicle procurement from feasibility through tendering, contract award, design, manufacturing, testing, commissioning leading to service introduction and maintenance of the new fleet.

The team began working on this latest project in early 2008 which resulted, after a detailed tendering process, in CAF being selected once more as the supplier of the new vehicles. The first batch of Class 4000 Units are due to be delivered in February 2011, with the last Unit due to be in service by 2013

Mal McGreevy, General Manager, Rail Services, NI Railways said “We were delighted to re-appoint Interfleet and walkerwarren to support the acquisition of the new Class 4000 DMU’s. Having worked successfully with us since 2001 in new vehicle procurement, they have carried on from where they left off on our previous contract, providing NI Railways with timely and professional advice and assistance during the tendering process for our newest trains. I am also pleased to confirm that, following our recent contract placement with CAF, they have been retained to continue assisting us throughout the remainder of this project.”
