8 szeptember 2008 - Heidelberg. Germany – depot/zajezdnia. I just noticed that this tram has some sort of subsidiary number – 299 – but I have no idea why this is. Perhaps we should record it as ‘299 234’. Other Heidelberg trams don’t seem to have this feature.Heidelberg. Germany – depot/zajezdnia.
