Fine tuning the LDEs

After getting some feedback on the forums, I had to decide how to correct issues that have been plaguing the layout from the start. As the layout shape is an E and there’s only one helix, the lower right corner next to the door there becomes a dead-end for all 3 decks. Ideally, if there was another helix at the end of the other arm of the E, this would not be an issue, but I did not want to put a helix around the column, so…

Dividing the layout into LDEs

I’ve been struggling to figure out what to do about getting to and from upper levels. That is why the section in the upper left corner of the plan (that nobody ever sees in the photos) is still undeveloped. Originally in my N Scale plan there was supposed to be a helix there, but now with H0 that helix is a bit bigger and that tipped off the scale for me, even though N scale helix was almost as big, square footage wise.

The helix for H0 is going to be a really modest one, barely adequate by any standard. A 24″ inner loop and 26.5″ outer, with an average grade of 2.3%. I wish that grade was 2% or less but there’s just no room to make it an oval or make it a bigger circle without sacrificing aisle and benchwork space. I might see if there’s some room for a triangle but knowing that I need a 24″ turn curve that might be out of question.

Another option is a gradual around the wall climb, a no-lix. Problem with that is I would either have to give up the walk-in aspect of the layout and put a swing gate at the entrance, or make trains turn back and go through the same scenery twice, on a different track. Either methods use more precious benchwork space all around the layout, unlike the helix which hogs the corner with its 20 sq. ft.

Dabbling with LDEs on the 1st Deck

Planning is going ahead and the next thing I thought to tackle would be LDEs (Layout Design Elements) and where could they be located on the layout, focusing on the 1st Deck at this time.

After reading about¬†Mark Lestico’s Cascade Sub on LDSIG Wiki, I found an interesting and new (to me) tidbit in there about determining how many LDEs¬†would fit along the main line.
