Signalling TT Solutions Limited trading as STT Solutions was formed in 2011 as a result of a management buyout of Ansaldo STS Ireland Ltd. which was originally formed in 1979 as WABCO Westinghouse Ltd., a wholly owned subsidiary of Union Switch and Signal Inc.  The company was formed to manufacture and supply signalling equipment for the Dublin Suburban (DART) project and continues to be the leading supplier of railway signalling equipment in the Irish market to this day.

In 1989 the parent company was acquired by Ansaldo Trasporti Spa of Naples, Italy.  A reorganisation in 1996 led to the formation of Ansaldo STS N.V. as a subsidiary of Finmeccanica Spa.  The company was recently launched on the Italian Stock Exchange as Ansaldo STS.  For further information on the Group please see www.ansaldo-sts.com and www.finmeccanica.it.
