The G7.1

 

 The Piko G7.1 may seem rather large but another kleinbahn in Thuringia ran one for many years, the model will be gently upgraded using this link as a reference and here  and here and finaly here Weathering using Humbrol powders 

This is a painting of the Kyffhäuser line by Peter König and the purchase of a bargain on eBay resulted in the first and only tender loco for Grafenwalde.

It runs very well

 

 It will be useful for the tourist trains

The G7.1 in service

The G7.1 locomotives were intended for goods duties especially on hilly routes. As a result, most of the engines went to the western German and Silesian railway divisions and by 1909, 1,002 examples had been delivered to the Prussian state railways whilst during the First World War these simple and robust locomotives were required for military use.

After the Second World War, the locomotives that ended up in the Deutsche Bundesbahn were mainly used in shunting duties and were retired by 1957. In the Deutsche Reichsbahn in East Germany the last G 7.1 was not retired until 1966, including 55 669 seen here at Potsdam.

 

The Piko model tender, unlike 55 669, does not have additional bunker extension it is the subject of a discussion on DSO Modellbahn started by Ulf Steckel. Possibly easier to make the extension from plasticard. 

Maybe using pieces from the Fleischmann 3T.12 tender may be suitable?
