Crossrail International welcomes Subterráneos de Buenos Aires to London for technical exchange on traction power systems

It was a real pleasure to welcome the team from Subterráneos de Buenos Aires S.E. (SBASE) to London last week.

We had some fantastic conversations around the challenges of upgrading traction power systems in complex urban rail networks, sharing experiences from both sides.

Huge thanks to Navitas Engineering Ltd for their valuable input throughout the visit, and to the SBASE team for the openness, expertise, and collaborative spirit they brought to every session.

It’s always inspiring to see how international collaboration helps move us all forward; combining knowledge to build safer, smarter, and more resilient transport systems.

Keith Wallace

CHAIR & NON-EXECUTIVE DIRECTOR

Keith Wallace was appointed Chairman of Crossrail International in June 2021.

A Chartered Director and Chartered Engineer, Keith has over 40 years of experience in the rail industry, including 20 years’ leadership experience at executive board level.

Keith commenced his career with British Rail as a sponsored student and graduate trainee, where he gained a thorough grounding in railway engineering and operations. He then moved into consultancy before joining what was then Scott Wilson Kirkpatrick & Partners as its first rail specialist, rising to become Chief Executive of Scott Wilson Railways and serving on the Executive Committee of Scott Wilson prior to its acquisition by URS Corporation, which in turn was acquired by AECOM.

Keith chaired URS/Scott Wilson’s Crossrail Programme Board overseeing the company’s £70m design contracts on Crossrail, including Paddington and Farringdon Stations, as well as leading multi-disciplinary teams in the planning and design of major rail projects that included the East London Line Extension, Airdrie to Bathgate Rail Link and West Coast Route Modernisation (WCRM) in the UK; the Athens Metro Extension in Greece; and the HSL Zuid high-speed railway in The Netherlands. He has visited more than 30 countries on rail business, gaining a keen understanding of differing cultures and practices.

As an independent consultant, Keith performed a Project Representative review, on behalf of the UK Department for Transport, of the proposed £20bn Phase 2 of High Speed 2 (HS2), Europe’s largest infrastructure project. He also served as Programme Director for Govia Thameslink Railway on the Thameslink Project; Managing Director of Serco Caledonian Sleeper; and spent one year as Chairman of Merseyrail (Serco/Abellio JV), adding to his experience and knowledge of railway operations and major rail change programmes.

Keith holds a BSc (Hons) in Civil Engineering from Heriot-Watt University in Edinburgh where he later served as Member of Court, the University’s governing body, and was a member of the Audit and Risk Committee. He is a Fellow of the Institution of Civil Engineers, the Chartered Institute of Logistics and Transport, the Chartered Institution of Highways and Transportation, and the Royal Society of Arts.

Keith is also a non-executive director of Dublin Bus, a bus operator in Dublin, Ireland; and Scottish Autism, a charity organisation dedicated to enabling autistic people to lead happy, healthy and fulfilling lives.

Felipe Castro Arenas

Regional Director, Colombia

Felipe Castro Arenas is Crossrail International’s (CI’s) Country Director for Colombia. Based in Bogotá, he is responsible for the management of CI’s commissions and the creation of new business opportunities throughout the country, as well as the Latin American region.

Felipe has 20 years of experience in the engineering and construction industries, with recent focus on the development of Colombia’s road and rail infrastructure. Prior to joining CI in April 2023, he spent five years at the British Embassy Colombia in Bogotá as Infrastructure Adviser for the Foreign, Commonwealth and Development Office’s UK-Colombia Prosperity Programme to support economic development, unlock economic opportunities, and drive growth in Colombia’s regions. Felipe was responsible for delivering the programme’s objectives around rail and urban development in Colombia, managing agreements with development banks, implementing partners, and leading the adaptation and adoption of UK tools for quality infrastructure development, including BIM (Building Information Modelling), HM Treasury’s Five Case Model (for Business Cases), and the Infrastructure and Project Authority’s (IPA’s) Project Routemap for complex, major projects.

Since the passing of Law 1508 in 2012, Colombia’s first Public-Private Partnership (PPP) law, Felipe has specialised in the technical, financial and legal assessment of infrastructure projects for attracting private investment. As Technical Adviser at Colombia’s National Infrastructure Agency (Agencia Nacional de Infraestructura, ANI), he successfully led the appraisals and approvals processes of the first unsolicited PPP proposals under the new law. These included two of the most complex 30+ years highway concessions crossing the Andes Mountains – between Bogotá and Villavicencio, and Ibagué and Cajamarca – which paved the way for these types of schemes to represent almost a third of the portfolio of the country’s transformational Fourth Generation (4G) Roads Concession Programme, a large-scale plan to create a nationwide toll road network with private sector participation.

Earlier in his career, Felipe spent time with a variety of Colombian contracting and manufacturing firms, specialising in innovative civil/structural engineering and construction of buildings and infrastructure.

He holds a BSc in Civil Engineering from the Julio Garavito School of Engineering (Escuela Colombiana de Ingeniería ‘Julio Garavito’) in Bogotá and an MSc in Construction Management and Engineering from the Delft University of Technology in The Netherlands. In 2013, selected by the US Embassy in Bogotá, Felipe completed the International Visitor Leadership Program (IVLP), a professional exchange program funded by the US Department of State’s Bureau of Educational and Cultural Affairs.
