For our friends far from here in Croatia I have a pleasure to tell, that the Finnish Tramway Society had a test run with Zagreb 2263 in Helsinki at Saturday the 12th January. The run took app. 2 hours and we passed the both Helsinki lines, 6 and 8, that will be those the tram will serve in regular service in the coming half a year.
I have experienced quite many tram cities around the world and I am glad to tell, that Crotram passed quite well the difficult trackwork in Helsinki. It runs much smoother than the Variotrams in Helsinki. The noise level inside is lower and the unit takes the curves smoothly and quietly. Both acceleration and brakeing were also smooth but still strong. The change from electric brakeing to mechanical (disk) brake had no jerk.
I also discussed with the drivers, and they thougt Crotram as a nice tool to work. Easy to operate and no need to think about the driving as with the elder Helsinki trams and Variotram.
As you may know, the Zagreb version is not suitable for the whole Helsinki network as is. Hills are steeper than in Zagreb. The distance from the axle to end of the car is too long and/or the free height of the end too low. Also a Helsinki tram requires torsional flexibility. Crotram as it is at the moment is rigid around the longitudial axle of the car - as are all the other trams in Helsinki - but with it's length of 30 meters this will cause problems. But all this is something that I might compare to the size of the shoes. The model might be OK, but you need to choose your number, i.e. adjust the model to each city's needs.
Anyway, it is nice to have Crotram here. And I may estimate the the citizens will be happy with it during the coming period in regular service.
There are some pictures available from this test run at the "Kuvat" (Pictures) folder in thread "
