My system plan
Below my system plan, made double track, allowing me to avoid a reversal of polarity reversal of levels - 2 loops out and - 1, as well as the creation of an additional track leading dead-end to a small station of goods.
This network l measures 2.50 m to 2.05 m and contains 4 levels; It develops about 67 meters of track.
Above the station hidden in the level - 2; access down the helical ramp which can be seen the end at the bottom left.
.. in bypassing the village and through a tunnel under the mountain, and then crossing the Valley on a long viaduct in curve to continue in the trench to the upper station, departure point for excursions to the Castle.
