I assume this means if QF are running late they'll look after you if you miss your train. Flew to FRA last year and QF were 2 hrs late, due to mech probs in SIN, and we missed our train and were out of pocket several hundred $$. Although, to QF's credit after intially unsuccessfully pursuing through Travel Insurance (at QF's request), QF came good with the $$$ (but only because I was a WP).
