Effective May 10, 2012 Invensys Rail Corp. acquired privately held PHW, Inc. from the current owner/managers for up to $24,000,000.00. The company will operate as a wholly owned subsidiary of Invensys Rail Corp. PHW, based in Pittsburgh, Pa., is a leading manufacturer of cab signaling systems and other fail-safe electronic train control systems for the North American railroad and mass transit industries.
PHW’s onboard system is used on the North East Corridor by Amtrak and associated railroads as part of Amtrak’s ACSES PTC system. ACSES is the first PTC system to be approved for operation by the Federal Railroad Administration under the requirements of the Rail Safety Improvement Act of 2008. Cab signaling systems make train operations more efficient, allow higher operating speeds and improve system safety. The PHW PTC products will be a major expansion of Invensys Rail’s North American PTC product line.
