United States

 
On January 1st, 2009, we at Union Switch & Signal began a new chapter in our history by transitioning our corporate name to Ansaldo STS USA.  The new name promotes the versatility and strength that comes from the integration of regional rail industry pioneers, with a combined 260 years of signaling experience and technological know-how, into the global leader, Ansaldo STS.
We want to assure you that our legacy of quality and customer service is not diminishing with our name change, but rather it is strengthening through thisunification.
