Fiducia ...
During the great depression of the 1930's a new and modern looking tram was designed and built by Wellington Tramways Corporation . It was made for, and debuted  at, the National Confidence Carnival in 1933, to help fundraise for the Mayor's distress fund.  It was a much needed confidence boost for the public of that time.  In latin Fiducia means reliance, trust confidence and loyalty.
