Line 33:

Modern [[electric multiple unit]] and [[diesel multiple unit]] vehicles often utilise a specialised [[Railway coupling|coupler]] that provides mechanical, electrical and pneumatic connections between vehicles. These couplers permit trains to be connected and disconnected automatically without the need for human intervention on the ground.

There are a few designs of fully automatic couplers in use worldwide, including the [[Scharfenberg coupler]], various [[Janney coupler|knuckle]] hybrids (such as the [[Tightlock coupling|Tightlock]], used in the UK), the [[WedgelockWedglock coupling]], [[Dellner coupling]]s (similar to [[Scharfenberg coupler]]s in appearance), and the [[BSI coupling]].

Multiple control technology is also used in [[push-pull train]]s operating with a standard locomotive at one end only. Control signals are either received from the cab as normal, or from a [[Control car|cab car]] at the other end that is connected to the locomotive by cables through the intermediate cars.
