Following on from the Star Class that he ordered from Robert Stephenson and Company, he designed a series of standardised and successful locomotive types starting with the Firefly and Sun classes of passenger locomotives, and the Leo and Hercules classes for goods trains. By 1846 Swindon Works had been established and was able to build its own locomotives. The most familiar from this period are the Iron Duke Class 2-2-2s with their driving wheels, a type that operated express trains right up to the end of the broad gauge in 1892. Gooch further developed the broad gauge locomotive fleet, producing the first bogie tank design for the steep and curving South Devon lines in 1849, and condensing locomotives for the Metropolitan Railway in 1862. He produced over 100 Ariadne class goods locomotives to a standardised design at a time when most classes ran to only ten or twenty locomotives, and components he designed were often interchangeable between different classes. With the acquisition of the northern standard gauge lines in 1854 came 56 locomotives, a second workshop at Wolverhampton, and Joseph Armstrong. Wolverhampton was responsible for maintaining standard gauge locomotives for many years, although Daniel Gooch did design some new locomotives that were built at Swindon and carried to Wolverhampton on special trucks. The first, the 57 class were 0-6-0 goods locomotives built in 1855. At the same time some 69 class passenger locomotives were built by Beyer, Peacock and Company in Manchester so were able to be transported on their own wheels. By the time that Armstrong replaced Gooch at Swindon in 1864 many more locomotives had been acquired with the Birkenhead and West Midland Railways.
