Pecan Street is an 8 feet (2.4 m) long but only 6 inches (15 cm) wide HO scale switching layout, built in two segments of 4 feet (1.2 m) length each. This somewhat unusual size results in a total surface area of a tad under 3.9 square feet, just squeezing it into the category of a "micro layout".

The extremely reduced width for HO scale affords just enough space for two parallel tracks, which is why Pecan Street was planned and built as a so-called "tuning fork layout" (albeit with a short extra siding thrown in for some extra visual and operational interest).
The "tuning fork" layout concept was never really seen as a switching puzzle - not by its original advocate Chris Ellis (who published Model Trains International magazine from 1996 to 2015 and first introduced the label for an "ultra simple multi-mode switching plan" in 2003), and certainly not by Lance Mindheim, who more recently has promoted the "one turnout layout" as a realistic track pattern for prototypical operation in an achievable format.

As a result, there are no etablished rules on how to operate a "tuning fork" as a switching puzzle, so I had to work out a set of rules allowing me to operate the Pecan Street tuning fork layout in that manner.

The following pages reflect the fact that Pecan Street is still very much "slow work in progress".
