A final note for the doubleheaded 9F (or 8F) discussion

THANK you for all your replies in the last couple of issues regarding double-headed 9Fs in BR days. As a final footnote (or perhaps not?), David Mitchell remarkably supplied another photograph of the very same train recorded by David Smith of Sheffield on June 23, 1967, as detailed in the last issue.

He confirms the identities of the two locomotives as ex-Crosti-boilered 9F

No. 92021 and conventional classmate No. 92159, his picture of the lengthy tanker train being taken as it departed from Neville Hill yard in Leeds.

He points out, however, that technically these were not both 9Fs, for the rebuilt Crostis were downgraded to power class 8F following the removal of their unsuccessful preheaters.
