Grossherzoglich Badischen Staatseisenbahn 2-2-0 Locomotives in Germany
Class Details by Steve Llanso of Sweat House Media
Class I d/Aurelia (Locobase 20242)
Data from [
], last accessed 6 August 2017.
This trio had a layout very similar to that of the Oldenburg Railway's T0 described in Locobase 9919. It too had two axles at the ends of the frame, which gave them a city-cab like look. Indeed, the type was nicknamed "Omnibus -Lokomotiven". Of course, the drum-type steam dome in the center of the boiler, Stephenson link motion eccentrics mounted outside of the wheels, and very tall, thin tapered stack established its steam-power origins.
The trio pulled up to three coaches each on a 2.2 km (1.4 mile) line between the main line and Ettingen.
