That means 35156,57,+59 have spent approx 8 years 10.5 months, from new, at WR, whereas -
of the last previous new double deckers for WR - (6092-96) - -
6093 stayed the longest, and did approx 8 years 11.5 months, from new at WR, so I think 35158 will need to stay the whole of August to equal that

(In 1967, six months before 6092-96, we received 6046-55 (also new), of which 6052 stayed the longest and did approx 9 years and 6 months).
I thought you would all like to know that !!
