 Except the passenger gangway....

 If anything the Tangara has MORE to stop a car tipping - the passenger
gangway. Conversly it also means a tiped car is more likely to pull over
its neighbour.
 Between a conventional coupler tearing out of its pocket and the covered
passenger gangway tearing lose, they probably come out similar.

 Tangara's are 'bouncy', its probably just that a good hole in the road is more
likely to make them bounce all the way off the rails.... The Kingsgrove set
left a wheel set behind, train bounced off its wheels ?
