Through the History of Märklin Catalog Title Pages.
The painting adorning this car shows Austria's largest steam locomotive, the class 12 of the BBÖ. It is running on the directional track of a main line with a heavy, important express train of the Thirties of the previous century. The baggage car behind the steam locomotive still has a cupola at the center of the roof. On the opposite track the observer will recognize probably the most striking distant signal of the world of railroading. It is also affectionately designated as the Fried Egg.This steam train has just passed under a large viaduct, which is also used by a main line. However, in this case an electrified main line! The Köfferli, class Ce 6/8 I of the SBB, also known as the mother of the legendary SBB Crocodile Ce 6/8 II or III, is running on this line with a mixed freight train that does not seem to end.A caption to go with this image could be: Swiss electric meets Austrian steam locomotive giant.The remarkable thing is the fact that the class 12 of the BBÖ is shown on several historic Märklin catalog title pages of that time. The prototype was built from 1928 to 1936, and at this time it was brand new and was still being built. However, this locomotive was never done by Märklin as a model.
