This is Roger's third layout. The layout is room-filling, measuring about 62' x 29', with three staging yards going through the walls into the garage. After 50 operating sessions, Roger has decided to stop those, and he is now in the process of starting to take down his layout, with perhaps preserving some sections to keep on modeling. Roger successfully completed the NMRA's MMR program.

The last of steam meets a new F3 set in Greencastle, Indiana. The track in this scene was installed by Dick Karnes, MMR, including the single slip switch and the crossing that he scratchbuilt. The F3 diesel units are by S-Helper Service and were converted to Phase I versions. All the structures, except those in the far background, were built from S-scale kits.

Number 450 is an American Models Pacific. Many details were added to make it resemble its Monon prototype. The truck is a Milestone Models kit.

Number 281 approaches the White River Bridge just south of Gosport, Indiana. The engine is a Southwind Models brass UP 2-8-0 with an Overland Models USRA tender. Both the engine and tender have had substantial changes applied to "Mononize" them. The cut stone is plaster, cast in molds made with Slater's "Plastikard" for a pattern. The bridge girders are sold as HO-scale.

Ed Loizeaux' Monon business car number one heads northbound on an inspection trip. The car is a custom-painted American Models Observation car in the red and gray passenger scheme used during the railroad's transition period.

USRA Light Mikado Number 550 waits on a siding at Wallace Junction while SW1 diesel engine DS50 positions its caboose. The Mike is an Overland brass model fitted with a capped stack and other characteristic Monon details. The track at Wallace Junction was installed by Dick Karnes, MMR.

The scene is Fourth Street in Lafayette, Indiana in the late 1940s. The houses are, left to right: Branchline Trains "Deluxe Farmhouse" kit; Wild West Models' "Pitkin House" kit; and the gray house was scratchbuilt by Goeff Stipps for Paul Scoles. The garages are HO-scale plastic kits with S-scale doors. All the fencing is HO-scale. The underpass stone walls are from Chooch.

The Monon's Fourth Street overpass was the most restricted spot on the line, requiring detours to other lines when taller equipment started being used. The F3A is brass from Overland Models.

Gosport's "run through" combination depot was built in the early 1880s and lasted into the diesel era. The model is scratchbuilt. The Pennsylvania Railroad is up to the right behind the depot in this view and intersects with the Monon at Gosport Junction to the north. The bunk and kitchen cars are modified Sunshine Models kits. The B&O round roof box car is Overland Models brass, as is the modified Light Mikado steamer. F3 number 65 is an S-Helper Service product.

The Monon had several wood trestles in southern Indiana. This one serves the limestone quarry district. The model was modified to fit the scene from one donated by Dick Karnes, MMR. The NW2 diesel is an S-Helper Service model. The box cars are Pacific Rail Shops kits. The caboose is scratchbuilt.

Limestone mined from quarries such as this one was a substantial source of tonnage for the Monon. Large blocks of stone cut from solid deposits were loaded onto flat cars and gondolas with giant "stone cranes" for further shaping at mills along the line. The material was used in buildings such as the Pentagon and the Empire State Building. These model cranes were built from HO-scale high-tension towers from Kibri, with other bits of styrene added. The model blocks are cast tinted hydrocal, drilled and split much like the real thing.

Taking inspiration from Brooks Stover, Roger Nulton spent some time "perfecting" a photo he had taken on his layout using the Adobe Photoshop software application. He just wanted to see what he could accomplish. This scene is of the McDoel Yard Coal Chutes on his layout, which was from a Mini-Structures kit. The particular challenge to this photo editing is the fact that this structure is no more than two inches from the front fascia, which seems to always be captured in the photos.

The completed caboose shop is part of the six buildings making up the Monon Shops complex (the distinctive chimneys are the only missing parts, to be added later). The transfer table is a Walthers model that Roger adapted for S-scale use, including re-doing the bridge track and building a new operator's cabin to match S-scale. The transfer table itself, according to Roger, is actually the correct size in S-scale for this particular installation.

This shows a closer view of the shop. To simplify construction, Roger fixed the doors in these positions.
