Helsinki, Finland.
Testing of a mock-up tram.
This mock-up tram is in the dimensions of the longer (34.5m) Transtech trams used for the Raide-Jokeri LRT. A prototype will be used on the existing tram network while the LRT is under construction, and this mock-up will determine any need for infrastructure changes.
