So, our anticipated layout plan is approximately 19 x 15. We plan to do two main lines (in a double loop configuration) (each approx. 75' in total length), a small classification yard (longest of 4 -6 tracks in it will be around 110"), 2-3 staging tracks (parallel to each other and each approx. 11-12' long), and a sort of tear-drop shaped elevated train section (3 tracks, NY subway style) with each EL loop having a total track length of approximately 30-33 feet. And, we plan to have at least 2-3 sidings. We're running DCS. With the MTH DCS supplement book instructions, supplemented by what I've read on-line, it seems each of my main loops should have at least 2-3 blocks, the switching yard would require another block, the EL another 2-3 blocks?? On top of that, the few switches (from what I've read) should be separately powered, and the accessories/lights on the layout also should be separately powered. If this is all correct (??), I would need at LEAST two TIUS and maybe three? This isn't even counting the sidings. Seems extreme given the small side of our planned layout.
Also, as I'm a total novice, how would I do star pattern wiring (as recommended by MTH) when I plan to drop power from each piece of sectional track - each MTH terminal has a max of 24 connection points?
Would SO appreciate advice.
Thanks!
