HARZ Mountain rail operator Harzer Schmalspurbahnen (HSB) in central Germany has been using one or more of its Class 199.8 'Harzkamel'V100 Ost diesel locos instead of steam locos or DMUs throughout the summer of 2020.
This is likely to continue for much of the rest of this year, although the routes operated change from week to week and are shown on the operators' website.
Ten mainline DR Class 112 (later DB Class 202) diesel-hydraulic locos were rebuilt between 1990-92 as six-axle metre-gauge locos, with the original aim of replacing steam.
German re-unification in 1990 led to a surge in tourist visitors to the Harz region and the railway so the plans to replace steam locos were abandoned.
They are known as 'Kamel' (Camel) because the centre cab 'hump'in six of the diesels remain in the HSB fleet, although not all are in use.
