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. The two companies were merged into Kaye & Ward, though they retained the imprint "Edmund Ward" to publish some titles, including the Railway Series.
Starting with Small Railway Engines in 1967, the imprint "Edmund Ward" was dropped and the Railway Series was published directly under the Kaye & Ward name.
