If you ask yourself what the difference is between a pure landscape diorama and a model railway layout, the answer is quite simple: the track! In most scales, including TT, the level of detail of motor vehicles, wagons, buildings, vegetation and other decorative objects is now so high that the perfect illusion is created by appropriate patina and lighting. There is one exception, however - the wheel-rail system. While many model railroaders now apply the highest standards to locomotives & Co. and the correct display of, for example, lines, labeling of revision data, the track and the wheels are largely neglected.
The idea of building a finer 1: 120 scale track is not new. There are some TT systems and modules that are equipped with tracks made of Pertinax sleepers and soldered Code 55 (1,39 mm) Rail profiles are operated. Unfortunately, the look of the sleepers doesn't quite convince me and the Code 55 profile is, although significantly lower than Tillig's Code 83 (2,03 mm), but clearly too chunky.
The company TT filigree uses the code 60 known from Märklin Z (1,57 mm) Rail profile, with plug-in base plates in plastic injection molding and real wood or plastic sleepers. In itself a promising track system, quite easy to build and suitable for non-precious metals. However, this track system can only be used from Era II onwards, since it represents the Reichsbahn superstructure K and, because it is NEM-compatible, relies on wide, prototypical wheels. Is this a problem? Yes, after all, you got yourself into your head, an operational diorama of Obstmühle station to be built in Saxony around 1913 (era I). On this route between Waldheim and Rochlitz there was now the 3rd order Saxon superstructure and the wish to display delicate undercarriages with narrow, exemplary wheels should also be taken into account. But what alternatives do you have as a newcomer?
Browsing helps! The H0purists have fantastic track construction and Klaus-Dieter Pfennig (DIT model) even a Prussian track, the construction principle of which can be wonderfully transferred to a Saxon track.
Thanks to a photo of the Klosterbach Bridge in Geringswalde, it could be seen that 6 meter long rails were laid between Waldheim and Rochlitz. A look at the book "The railway construction industry for railway masters and building supervisors, as instructions for practical service and in preparation for the railway foreman examination" by Ernst Susemihl (1899) then revealed that it must be the 3rd order superstructure (cf. Susemihl (1899), pp. 100-102).
