On 15 or 16 March 1835, Hercules passed Emmerich towing the barges: Koophandel, skipper Von Böningen (2,961 cwt) destined to Coblenz; Harmonie skipper H. Köhler (3,453 cwt) to Mannheim; and that of skipper Schmitz (3,395 cwt) also to Mannheim. On 17 March 1835 Hercules was seen before Düsseldorf towing four heavily loaded barges aligned in two pairs behind each other. This was an experiment that made the news. The enormous power of Hercules was noted. On 19 March Hercules brought Koophandel, Harmonie, and two barges of 1,930 cwt and 3,305 cwt into the harbor of Cologne. The heavier train confirms that the compound engines of Hercules were not yet finished when she was on the Rhine before the Belgian revolution. On 1 June, she towed the East Indies ship Stad 's Gravenhage into Hellevoetsluis. In 1836 Hercules also served on the Rhine, as was the case in 1838.
