what is it?

The Irish AEC railcars were Associated Equipment Company (AEC)–engined diesel multiple units (normally termed railcars in Ireland) that operated InterCity and suburban services on the Irish railway system between 1950 and 1975. Many CIÉ examples were later converted for push–pull operation with diesel locomotives, finally being withdrawn when displaced by the electric Dublin Area Rapid Transit service in the mid-1980s.
