Hi,
I have been wondering about the FREMO standard end forms: I cannot understand why the drawings of the standard end pieces never show the rail heads? To me the most important thing is to get the rails joined together.
The rail top (SO) is 1300 mm (+/-10 mm) from the floor. To join the modules together one must know the hole positions related to top of rail head (SO). The holes are specified as 10mm diameter, and the joining bolts are specified as M8. This gives +/- 1 mm play. Looking at the prototype railway line's roadbed profile ('querschnitt des bahnkörpers'), one will notice that the sleepers are completely buried into the ballast, and that only the top of the sleeper is visible from the 'oberbau' of the roadbed. The only german prototype drawing of the roadbed ('bahnkörper') I managed to google is this:
The standard:
Looking at the photos of PowerPoint shows at:
Why is it that one should deduct the rail position in the end profile of FREMO module related to the holes of the end profile?
Isn't the relationship of rail heads and fixing holes the most important thing in order to get trains across the module interface?
Should not the finished scenery/ballast surface and rail heads be somehow displayed on the standard end profile drawings?
