Standards
For many years, the National Model Railroad Association (NMRA) has promulgated standards to allow for the easy interchange of models of North American equipment regardless of the manufacturer. For European modelers, MOROP performs a similar function with their Normen Europäischer Modellbahnen (NEM) or European Model Railroad Standards.
The NEM standards are "official" in their original German and French. Beginning with my translation attempts, MOROP is now making the standards available in English.

Some of the notations are incorporated as graphics and could not be substituted by English words. Here's a glossary:
- Arbeitsbereich = Working Range
- Größte Seitenabweichung = Maximum Lateral Shift (zig-zag)
- Höchste Lage (Arbeitslage) = Highest Position
- Kontur bei Gleisbogen = Contour on Curves
- Maßtabelle = Table of Dimensions
- Nenngröße = Scale
- Normallage (Normalarbeitslage) = Normal Position
- Nutzbare Schleifbreite = Pantograph Collector Width
- Radius des Gleisbogens = Curve Radius
- Tiefste Lage (Arbeitslage) = Lowest Position
- Wippenbreite = Pantograph Overall Width
Here then are the Norms available in English; some open the file from MOROP's own site in a new window; others (displayed in this pane) are my latest translations that are as yet not posted by the organization:
