Although the train elements were listed in the catalogues, this one is the June
1938 one, so far there was no proof that these elements were available separately.
Note that the box was printed in Great Britain, not in England but the label was printed in England.
The code 1/534/.5 means May 1934 so the DINKY TOYS label was applied to a Hornby Series box.
