Well, I fear, the method can cause problems later in track laying. Therefore, I prefer to wait until then, and I work on other parts.
From the project.
This is a part of a real railway, half-fictive. For the time being in plan 3 middle stations, with average 6-12 tracks; 3 stops; and a big coal industrial center, with coal grading station, nearby by station "1".
Landscape (IRL) has deep valleys, which are crossed by high embankments (the highest approx. 40m), and high hills. I will try to imitate this terrain. Railway is constantly on long uphills or downhills. Double tracks, SBL block signals between stations, vmax in current plan: 120km/h, but curves suitable to 140km/h.
Total length app. 35km (2+4km to exits) , currently layed: 19km, and a station with 1 complete junctions area, which is only on plain.
