Modeling the Atlantic & Yadkin Railway
Building an accurate HO layout circa 1934 — equipment, freight cars, structures, and research methodology for a prototype-faithful model railroad.
About This Section
This section documents the process of modeling the A&Y as faithfully as the historical record allows. The emphasis is Railroad Prototype Modeling (RPM) — the practice of working from primary sources toward accuracy in equipment, operations, and scenery, while accepting that perfection at HO scale is a goal rather than a destination. Several contributors to this site are regulars at RPM meets held around the country; their insights and photographic evidence inform both the history and the modeling sections.
Presentations given at RPM and NRHS meetings are a primary source for the methodology pages here, covering freight car fleet composition, custom decal techniques, styrene scratchbuilding, and the statistical analysis of what cars actually ran on the Winston-Salem Division in 1934.
Why 1934?
The choice of 1934 as the modeling era reflects where the primary sources are richest. The A&Y’s ICC annual reports span the full independent period. The Henry F. Snow conductor logs — transcribed by Al Brown — cover 215 trains on the Southern Railway’s Winston-Salem Division in 1934, giving car-by-car detail on type, road name, commodity, and weight. The 1934 ORER provides a detailed breakdown of the Southern’s fleet by car type and MCB class. Together these sources allow a statistically defensible answer to the question every modeler eventually faces: what should actually be in this train?
Nineteen thirty-four also sits at an interesting moment in A&Y history: the receivership that began in 1924 is a decade old, passenger service is still running (it ended ca. 1937–1939), and the locomotive roster is at its most photogenic — the H, J, and K class Consolidations are all active, and the RF&P Ten Wheelers have just arrived. The era is well-photographed relative to the line’s history, and the physical plant is documented in the ICC valuation-era photos taken a decade or so earlier.
The A&Y as a Modeling Subject
The A&Y presents an unusual set of modeling freedoms and constraints. On the freedom side: the railroad owned no freight cars. Any pre-1950 Southern Railway prototype freight car is a candidate — flat cars, gondolas, and boxcars especially, given the mineral, forest, and agricultural products the line carried. The thriving furniture, textile, and tobacco industries along the line demanded boxcars; Greensboro hosted textile, fertilizer, and metalworking industries requiring boxcars and gondolas. Hoppers were present but not dominant — the Egypt coal mine closed in 1928, the Gulf clay pit supplied brick and terra cotta pipe operations, and domestic coal deliveries and the Duke Power plant in Greensboro kept some hoppers moving, especially south of the main junction.
The A&Y connected with five Class 1 railroads: the Southern, ACL, SAL, original Norfolk & Southern, and the N&W. Freight cars from all five and their interchange partners would plausibly appear. Statistical analysis of the 1934 Snow conductor logs for the Winston-Salem Division — adjacent in geography and using the same interchange points — puts the realistic fleet at roughly 65% boxcars, 19% hoppers, 6% tank cars, 4% gondolas, 2% reefers, and small fractions of flats and stock cars. Southern cars dominate all train types; N&W is the second most common road name at around 14%.
On the constraint side: the A&Y leased its locomotives almost exclusively from the Southern Railway. The three ex-RF&P Ten Wheelers (Nos. 106, 109, 113) were the only A&Y-owned motive power. This actually simplifies the equipment roster considerably — any correct Southern Railway steam locomotive of the appropriate class is prototypically justified.
Cabooses followed the same pattern: mostly Southern leases, with two ex-RF&P cars (861, 862) and two ex-N&W CF-class cars purchased outright and renumbered into the 864–865 range. No photographs of a Southern-lettered caboose in A&Y service have surfaced. Two A&Y-lettered cabooses are photographed: No. 862 (RF&P origin), and one of the N&W CF-class cars — likely No. 865 — caught in A&Y lettering in the January 1948 Greensboro snowstorm scene. The specific number on the A&Y-lettered car is not legible in that photo; 865 is only readable in a later Pomona shot already in Southern lettering after the 1950 absorption. Both are strong modeling targets.
What’s Here

Kitbashing, scratchbuilding, and detailing projects including custom decal production using white laser toner and Cricut-cut styrene structures.
Locomotives & Cabs
Model versions of the A&Y’s leased Consolidations, the RF&P Ten Wheelers, and the RF&P and N&W cabooses.
Stations & Structures
Modeling the A&Y’s characteristic two-tone board-and-batten combination depots, freight houses, and industry structures.
Calibrating Wheel Reports
Testing the Gilbert-Nelson hypothesis using the 1934 Winston-Salem Division data — how car-type mix differs between branch mixed trains and through freights.
Freight Car Variants
Identifying which specific Southern Railway 40-foot XA truss-rod and steel boxcar variants were in service in 1934 — the difference between “plausible” and “right.”
Railroad Prototype Modeling Meets
Railroad Prototype Modeling (RPM) meets are gatherings focused on historically accurate scale modeling — clinics on research methods and construction techniques, model displays, vendor tables, and conversations with modelers who share primary-source evidence rather than “close enough.” They are quite different from general model railroad shows: the emphasis is on the prototype photograph and document as the standard, and the culture rewards finding the obscure reference that settles a detail question. For a good overview of what RPM is and what meets are like, John Golden’s Railroad Prototype Modeler site is the best starting point.
Several contributors to this site are regulars at RPM meets. The meets below are ones the site author has attended or presented at:
- St. Louis RPM — the largest and arguably the founding meet; not yet attended but on the list
- Middle Atlantic RPM (MARPM) — presented here; also active on Facebook
- Chicagoland RPM — held in Naperville, IL; presented here (the Cricut scratchbuilding and structures clinic)
- RPM Valley Forge — held at the Desmond Conference Center in Malvern, PA; presented here
- RPM-East — alternates yearly between eastern PA (Valley Forge / Malvern area) and western PA (Greensburg, near Pittsburgh); presented here. An A&Y caboose model appears in the 2025 photo gallery on that site.
- Carolinas RPM — the nearest meet to the A&Y’s territory; attended when possible
