Thank you guys for the nice and warm replies.
The lamps are these:
http://www.busch-model.com/katalog/e/artikel/8620-1g.htmI went to a modelshop to buy some grass and found these. I'm not really happy about them: the quality of the plastic is crappy at best, the wires to connect to a transfo are way to short and since they are glued together replacing the lamp will become difficult!
But they look nice don't they?
I do hope Geobra will make a tram someday
. Preferably an old style streetcar.
As for the nuns, ras: They were spying on which girls were going to the Cinema so they could punish them at school the next day (This really happened in my grandfathers day).
