Size: 3' x 16'
Scale: HO
Era: Any
Type: Technical Demonstration
Built: 2005 to present
Description: The four sub-modules fit together to form a 16 ft. module. This picture above shows the left-hand end (from the operator’s viewpoint). There is a helix which starts below the level of the Club main tracks and raises trains to above the level of the main tracks to allow them to pass over the latter. The reverse is also true, as the helix will be two-way working. This module was also discussed in greater detail in my December 2005 column.
Here are the notes that influenced the design of my
new modules:
1. Straight tracks in the staging area for ease of
putting rolling stock on the track.
2. Everything within arms reach from the operator
side of the module.
3. Two tracks for the Club tracks, but configured to
do something slightly more interesting than just go straight through
from end to end. Club tracks are independent from other parts of the
layout.
4. Provide multiple levels for track (except the Club
tracks!). Non-Club tracks will pass above and below the Club tracks.
5. Demonstrate two methods whereby trains gain or
lose elevation in a small space, namely, zigzag (switchback) and spiral.
6. Tolerate sharp curvature, and select rolling sto
ck accordingly. Also tolerate short trains to fit within the available
space.
7. Provide automatic control, under DCC, outside the
staging area, manual control within the staging area, and head-in and
head-out procedures to interface between the two (as in my present demo
module, but more complex).
8. The automatic control will include two-way working
on a single track, with passing loops, something I have not attempted
before.
9. Pay great attention to track quality. Nothing is
more frustrating for automatic control than frequent derailments and
uncouplings.
