Forty-two largely identical locomotives were delivered by the Sächsische Maschinenfabrik, formerly Richard Hartmann, to the city of Chemnitz in the period from 1882 to 1894.

The length of the locomotive and the height of the centre of the boiler above the rails were also identical on all models.

The locomotives of the last two batches had a steam dome, whilst the older ones just had a Regleraufsatz.

98 7069 became an industrial engine at the repair shop at Chemnitz, but was transferred to the Deutsche Reichsbahn fleet in 1951 as 98 7051.

[1] Another engine built in 1889 by the Sächsische Maschinenfabrik with running number 1418 differed from the other H VII T stock in that it had a longer axle base (2,500 mm), larger coupled wheels and a higher top speed of 45 km/h.
