The idea is to decorate each carriage making them look like a traditional red painted chocolaterie with its striped awnings. The windows of the tram will be like the shop windows displaying the different varieties of chocolate.
The interior of the carriage could be decorated with some images of chocolates or a typical glass vitrine full of Halloren products making you feel you are inside the store.
At the stations, there could be some images of chocolate sticked on the shelters glass or on the pavement, sparking the curiosity of passengers that as soon as they see the tram, will want to hop aboard!
