--- title: "XMU - Front coupler" canonical: "/xmu-front-coupler" published: 2026-10-09 --- # XMU - Front coupler ## Frame ## Frame **Rail** **XMU** **Front couplers** ## Frame ### Type 10 ###### FRONT COUPLERS ##### Type 10 ##### Automatic coupler type 10 The automatic coupler head type 10 is designed for regional and intercity, high-speed trains and railcars. It is compliant with the Technical Specifications for Interoperability (TSI) for the European rail system. This automatic coupler system is part of Dellner’s modular design concept, which is characterised by excellent spare parts availability and very low maintenance costs. **Customer benefits** The automatic coupler type 10 is supplied with a pivot anchor as a deformation unit for crash absorption. The train coupler can be fully integrated with Dellner’s Crash Energy Management system. It comes as a top mounted electrical coupler including D-REX ethernet connection and pneumatic connections for main air and break air systems. Product details TSI compliant type 10 mechanical coupler Centre section with gas-hydraulic damper Pivot anchor for enhanced crash energy absorption Total energy absorption: 1.6 MJ Top mounted electrical coupler including D-REX (100 Mbit Ethernet connection) Pneumatic connections for main air and break air Buff/Draft strength: 1500/1000 kN (regional and inter-city applications) ### Type 12 ###### FRONT COUPLERS ##### Type 12 ##### Automatic coupler type 12 The type 12 automatic coupler head is designed for regional, intercity, and high-speed trains as well as metros. The coupler head type 12 is part of Dellner\`s modular design concept. It comes with a pivot anchor with an integrated release function, allowing the coupler to shear off in the event of a collision. **Customer benefits** Product details Centre section with gas hydraulic damper Pivot anchor with internal release function Side guide horn for enhanced gathering range Bottom mounted electrical coupler including D-REX (100 Mbit Ethernet connection) Pneumatic connections for main air and uncoupling air Buff/Draft strength: 1500/850 kN ### Type H coupler ###### FRONT COUPLERS ##### Type H coupler ##### Tight lock type H coupler The tight-lock Type H coupler, like the Knuckle coupler, is based on the design of the Janney coupler. This type of coupler is particularly common in the USA. **Customer benefits** The Dellner tight lock type H is available for regional, intercity, high-speed trains and railcars. It complies with the American Public Transportation Association’s (APTA) PR-CS-RP-019-12 Rail Transit Standard. The coupler features an anti-rotation joint, and its design ensures that, in the event of a collision, the end frames are brought together in a way that minimizes vertical and lateral movement between the coupled vehicles and the impacting vehicles. The tight-lock Type H coupler is rigorously tested under both static and dynamic conditions and is equipped with a mechanical Knuckle coupler head. It features a rubber draft gear for regenerative energy absorption, while non-regenerative energy absorption is controlled by a deformation tube. The force and stroke characteristics of the deformation tube can be adjusted to meet the crash energy management requirements of the vehicle manufacturer. Product details For regional, intercity, high-speed trains and railcars Mechanical coupler: AAR Knuckle type Capacity: buff and draft (3650 kN / 2000 kN) Anti-rotation (203 kN-m) Spherical rubber bearing pivot Shear indicator Simple mounting with four bolts ### BSI ###### FRONT COUPLERS ##### BSI ##### Automatic coupler BSI The name of the BSI automatic coupler dates back to the German company “Bergische Stahl-Industrie” (BSI). The BSI coupler head was originally developed for light rail vehicles for automatically coupling and uncoupling wagons but is now also used in a larger number of passenger trains. **Customer benefits** Dellner’s BSI automatic coupler is designed for regional and intercity trains, metros, light rail vehicles and trams. It is part of Dellner’s modular design concept and features a rotating anchor as a deformation unit for crash absorption. The BSI coupler can be offered for all applications with Dellner’s patented safety locking device. Product details Centre section with gas-hydraulic damper Pivot anchor for enhanced deformation absorption Total energy absorption: 1 MJ Pneumatic connections for main air Impact/tensile strength 1000/600 kN ### Type SA3 ###### FRONT COUPLERS ##### Type SA3 ##### Automatic coupler type SA3 The SA3 semi-automatic coupler head for regional and intercity trains is designed in accordance with the Eastern European coupler standard. The coupler head is part of Dellner’s modular design concept, offering excellent spare-parts availability and very low maintenance costs. The coupler type SA3 comes with a pivot anchor as a deformation unit for crash absorption. **Customer benefits** Product details SA3 coupler head Strong and safe design Centre section with deformation tube Pivot anchor for enhanced deformation absorption ### Type Tomlinson ###### FRONT COUPLERS ##### Type Tomlinson ##### Automatic coupler type Tomlinson The Tomlinson automatic coupler head consists of two square metal hooks that interlock when coupled. At Dellner, the Tomlinson automatic coupler is available for regional and intercity trains, metros, light rail and trams. **Customer benefits** The Thomson coupler is part of Dellner’s modular design concept, providing improved spare-parts availability and lower maintenance costs for train operators, as well as shorter delivery times for train builders. It features a horizontally mounted pivot anchor, allowing for better integration into the car body. Product details Centre section with integrated shear-off in regenerative buffer Horizontally mounted pivot anchor for enhanced interface integration Pneumatic connections for main air and break air Pneumatic centring device Radial carrier Buff/Draft strength: 734/677 kN ### Type Schwab ###### FRONT COUPLERS ##### Type Schwab ##### Automatic couplers type Schwab Fully automatic front coupler with an excellent performance record, installed in various trains across Europe in mainlines, metros and LRVs. Enhanced safety through a redundant locking mechanism. **Customer benefits** Proven in service in Switzerland, with Schweizerische Bundesbahnen (SBB) and several private operators. Product details Buff/Draft strength: 1500/850 kN Operating Temperature: 25° C to 70° C Compact design, lightweight, with extended gathering range Capable of uncoupling with draw force up to 300 kN Ideal for winter conditions due to simplified, closed design at the coupling interface and intelligent heating system. **Type 10** **Type 12** **Type H coupler** **BSI** **Type SA3** **Type Tomlinson** **Type Schwab** ## Frame
