Research targets specific engineering outcomes, equipment and substitute products supporting construction, operation and maintenance.

Routes and urban space
Urban rail affects station areas, transfers and development patterns as well as transport. Consider station connections, depots and integrated development alongside route length.
Construction and technical capacity
Coordinate route construction, bridges, tunnels, track, power, signalling, rolling stock and maintenance. Research must be applicable to construction, commissioning and long-term operation.
For planned or preparatory routes, distinguish study options, approved schemes and work authorised to begin. Long-term network targets are different from current construction quantities.
Project coordination
Rail projects cross multiple districts and interfaces. Existing roads, utility networks, public spaces and neighbouring projects require coordination to control construction impacts on the city.
