The AAR/APTA TypeH TightLock coupler is a Janney automatic coupler typically used on North American mainline passenger cars. TypeH couplers have mechanical features to reduce slack action and improve safety, but remains compatible with Janney/AAR TypeE and TypeF couplers. TypeH couplers may also be fitted with automatic air and electrical connections. Management and development of TypeH coupler standards have been transferred from the AAR to American Public Transportation Association (APTA). The AAR/APTA standard mounting height for TypeH couplers is ATOR.〔AAR Manual of Standards and Recommended Practices, Section S, Part I:Casting Details, Issue 06/2007〕 Rail operators that commonly use TypeH couplers include Amtrak, Agence métropolitaine de transport, GO Transit, Via Rail and West Coast Express. TypeH couplers have also seen very limited use on British Railways electric multiple units (EMUs) such as the Bombardier "Electrostar", though recently, Dellner or Scharfenberg couplers are being used instead. The AAR TypeF TightLock coupler〔(TypeF coupler )〕 is a Janney automatic coupler typically used on North American gondola cars that go through rotary car dumpers as well as on some tank cars. Tank cars carrying hazardous materials are equipped with AAR TypeE double shelf couplers.〔()〕〔()〕 File:MBTA commuter car headend.agr.jpg|TightLock coupler on a MBTA commuter car also showing head end power and train control connections.
