Typically, TDI is commissioned to undertake feasibility, concept, styling, interior design and production engineering assignments for high speed trains, metros, light rail systems, monorails, automated people movers, buses and commercial vehicles. In many cases, TDI has engineered complete vehicle car-bodies including for electric buses and lightweight trains.
In 2016, TDI won the Global Light Rail Awards for 'Outstanding Engineering Achievement' in the design of its own brand 'ULR Express' diesel-electric railcar.
In public transport, project examples include the design of saloons, vestibules, toilet modules, driving cabs and control desks, detrainment systems, passenger seating, and infotainment facilities for new-build vehicles, as well as complete refurbishment solutions. TDI is able to develop conceptual designs through to full production detailing and documentation to requisite European TSI and (British) Rail Group Standards.
In addition to vehicles, expertise also extends to the development of urban realm and related infrastructure components, such as ticket offices, street furniture, signage and passenger information systems. TDI employs specialist industrial designers, ergonomists and mechanical engineers to develop fully styled, fully engineered solutions against individual customer’s own technical performance specifications and industrial design briefs. This ‘one-stop-shop' approach includes the following range of services:
- market research
- interior & industrial design
- feasibility studies & bid support
- vehicle styling
- graphics, liveries & corporate identities
- human factors/ergonomics
- 3D computer modelling in Catia V5, ProEngineer/Creo Elements & Rhino
- CGI animations and walk-throughs
- scale models, full size mock-ups & prototypes
- mechanical engineering
- finite element analysis (FEA) & crash simulations
- production design & documentation
- full manufacturing drawings & manuals
- project management
Since 2005, TDI has worked extensively on production builds for companies such as Alstom, Bombardier and Siemens on passenger interiors and driver's cabs for metro and mainline rolling stock in the UK, Germany, France, Poland, Belgium and China.
