Fireman Bruno U. throws another full shovel of coal into the firebox of the four-cylinder compound express steam locomotive A 3/5 # 705 from SBB Historic, on the return trip over the Thurtal mainline from Romanshorn towards Winterthur-Kloten-Regensdorf to Brugg AG. Built in 1904 by SLM Winterthur, the locomotive runs extremely smoothly at an instantaneous speed of around 90 km/h, the maximum speed is 100 km/h. The association steam group Zürich (VDZ Verein Dampfgruppe Zürich) made a more then 3 years large overhaul and this was the final test and celebration run for the people which worked for and donators.
