|The Transport Museum Society of Ireland began with an abortive 1949 effort to preserve three Dublin trams. Totally voluntary, the Society became a limited company in 1971 and is now a registered charity, operating to international museum standards.
The museum is located in the Heritage Depot, Howth Demesne, Howth, Ireland. On 1st September 2001, the collection, increasing at an annual average rate of five, totalled 170 (average age 46 years). Sixty out of the 100 vehicles currently in Howth are on display, and others can be inspected by prior arrangement. The oldest items date from 1883, the newest 1984,
