Later this year, I will set up a large Lego Train 9V display at my home in Knivsta/Sweden.
The track can be summarized as follows:
* "Train climbing wall" (5,6 m wide and 1 m deep)
* 4 different levels:
Level -1: 50 cm above ground (mainly train yard)
Level 0: 90 cm a.g. (partially train yard)
Level +1: 205 cm a.g. (destination level with two electrically operated crossover-switches)
Level +2: 220 cm a.g. (Double High Speed Track)
* 2 ramps à 6 m (including 180 degree curves each) connecting level -1 and level 0 (inclination approx. 8 percent)
* 2 x 4 ramps à 6 m ( incl. 180 degree curves each) connecting level +1 and level 0 (inclination approx. 8 percent)
* 2 Altitude Adjustment Circles (360 degrees) connecting level +2 and level +1 (inclination approx. 8 percent)
* Double High Speed Track (2x25 m) with four 90 degree curves, whereof two inclined
* Total track length approx. 175 meters
* Requirement to run 3 trains independantly
* Most trains equipped with two 9V engines, Santa Fe and Horizon Express with 4 engines each
One of the major challenges will be power supply. I would appreciate any advice on this matter, particularly from those who have experience in building large tracks of similar size. Inclinations will certainly add to the complexity. Just linking up regular 9V transformers will probably require 15 - 20 transformers, which would certainly be a major challenge to operate ...
