Designed by Johann Andreas Schubert, Saxonia was the first locomotive to be built in Germany. According to the Dresden history website [] (15 December 2006), Schubert employed classic "industrial spying" techniques to gather technical knowledge in many areas from his expenses-paid trips to England beginning in 1834.
Among the results was this small, but ground-breaking locomotive. Like almost all of the early engines, its firebox stood vertically, surmounted by a flared cap and safety valve stand. Bright red drivers, spoked in 12 flower petals per wheel, led a smaller trailing axle. Handsome wood lagging clad the boiler, which was topped by a brightly polished brass steam dome just behind the tall stack equipped with a spark-arresting mesh basket at the top.
Saxonia continued in service for almost 20 years after its first run on 4 April 1839.
