In 1952, Franklyn Edmund Ward sold his eponymous publishing house to the London printers, Straker Brothers Ltd., who had also taken over another small publisher, Nicholas Kaye Limited. The two companies were merged into Kaye & Ward, though they retained the "Edmund Ward" imprint to publish some titles, including the Railway Series.
On 25th April 1998, Reed International sold their children's books division to Egmont UK Limited and the copyright of the Railway Series to the Britt Allcroft Company for £13.5 million. Egmont acquired the rights to publish the Railway Series, and in the same year they published the new format versions of series.
Kaye & Ward remains in being as part of Egmont, but is dormant.
