These Yorkshires were used mainly to pull mail and passenger coaches, hence their name. Called by some the "New Cleveland Bay", foreigners often could not distinguish between the two breeds, and many horses registered as Cleveland Bays in European coach horse studbooks were actually Yorkshire Coach Horses.[35] In the 19th century, the Cleveland Bay was crossed with French and Belgian draft horses to create the Vladimir Heavy Draft, a Russian breed developed to fill that country's need for a heavy draft breed.[4][36]
