From the link I gave says 

"Errorneous ways
rel_id 	2666822

Examining the sequence of ways in JOSM they are not is sequence between way 285071338 and Way: 144184406. There are several sequences that need changing. 

This also brakes 

India Pacific relation 3134294 - gap.


Northshore & Western line relation 9806974 gap

Gap between Way: 904363665 and Way: 145390717 

and possibly others, the QA tool only catches so many before it moves on. There are some 20 relations in this changeset that were altered, not all of them are Public Transport version 2.
