Historical tram

Met today a historical tram BS 1 in the city. The year of construction was 1917 . BS means Brandö Spårväg also Brandö Tramway Company. The old streetcar worked till 1954 and belongs now to the Helsinki Tram Museum. No, this charter tram is not really it but a working replica. Should i go to the Tram Museum some sunny day, never been there. Those old vintage objects are so nice.
