Tangent Scale Models seventh caboose model is the HO Scale Southern Railway Gantt Manufacturing Company Bay Window Caboose System. This Southern Railway system covers the 1969-1974 deliveries of cabooses from Gantt Manufacturing. These 253 bay window cabooses served the SOU, and later NS, into the mid-1990s. After railroads purged large portions of caboose fleets, some SOU survivors made it into the 2000s and beyond, including one 2014 repaint into the NS/SOU Heritage scheme! Some are still used in today’s world of NS shoving platforms. These Southern cabooses were built by Gantt Manufacturing in Greenville, South Carolina and are easily recognizable with welded construction, terminating Stanray diagonal-panel roof edge, large windows, and bright “Fire Protection Red” paint. This Tangent caboose marks the first “high-detail” RTR Southern Railway caboose replica in HO scale, and is being released today.
By 1969, the Southern Railway and its subsidiaries served 13 states, with over 10,000 miles of track. With the slogan “The Southern Serves the South,” freight schedules cris-crossed the southeast. The railroad modernized its locomotive fleet with second generation EMD and GE power through the 1960s and 1970s. New cabooses were part of this modernization program, since the 1940s-early-1950s SOU Hayne Car Shops-built steel bay window cabooses were showing their age and needed replacement. To that end, Southern turned to Gantt Manufacturing to build several orders of new and “modern” steel bay window cabooses in both road service and local service configurations.
These cabooses were all delivered in Southern’s iconic red paint and proudly ran system wide from the hottest manifest trains down to the meandering local trains. While the first group of Gantt cabooses were built with running boards in 1969, these fixtures were soon removed. By 1970, new caboose deliveries were showing up with a modern, no-roof-walkway look. Local service cabooses stood out with yellow bay windows, while the road cabooses were solid red. The Local Service cabooses would be rebuilt in the late 1970s with roof-top solar panels to provide marker light power. The road cabooses were equipped with truck axle-mounted generators to charge the battery system.
Tangent Southern Railway Caboose System covers the 1970- through today era, and includes the following Gantt-built series:
Through the 1970s and 1980s, these Gantt cabooses would receive various versions of Southern’s red paint and make up the “core” of the Southern caboose fleet! If you see a red Southern caboose, it almost always is one of these! The cabooses served widely on Southern Railway rails, as well as offline in many instances either via run through operations or trackage rights. In addition to the bright “Southern” lettering, some of these cabooses were stenciled for Southern’s subsidiary Central of Georgia, carrying small “CG” or “C of G” initials.
So, if you model St. Louis, Danville, Birmingham, New Orleans, Macon, Atlanta, Jacksonville, Alexandria, Asheville, or somewhere else in the many places the 10,000+ mile Southern Railway served, Tangent Scale Models have a caboose for you! Oh, and don’t forget that these cabooses have been documented offline in places where you would not expect them, either in a “normal” run-through arrangement or an unplanned situation – so if you model a Southern interchange railroad or just love classic Southern/NS power, now is your chance!
It’s difficult to understate the importance of these Southern-design Gantt cabooses, as they were the primary road cabooses for the last 14 years of the Southern and first decade-plus of Norfolk Southern. This era is an incredible period of change for railroads like the SOU, and it is easy to see why Tangent has planted its Southern caboose flag here.
And now, on to the models! The Southern Railway Gantt Manufacturing Company Bay Window Caboose System is a state of the art, dimensionally-accurate group of scale replicas with highly accurate “true-to-life” colors and precise letter stencils. Tangent Scale Models SOU cabooses were designed from meticulous field dimensions, and include incredible levels of detail such as multiple era-specific bodies, roofs, ends, two different underframe assembly options, brake wheel options, caboose truck options, generator options, solar panel installation options, toilet air tank, rooftop antenna, multiple smoke stacks, accurately scaled window treatments, plus beautiful steps and end platforms with accurate tread detail. Inside the model is an accurate SOU Gantt-applied interior. Tangent Scale Models Southern cabooses include interior lighting, plus FRA End Light (SOU-style, i.e. non-flashing!) options that are appropriate for the paint scheme era of each replica. These “no fuss” track-powered interior and exterior lights are compatible with DC or DCC setups right out of the box (a simple wand included in the box activates the lights). Finally, Tangent Scale Models ready-to-operate replicas include “near-scale” draft gear box including side “key” detail, coupler lift bars accompanying Kadee scale couplers, sufficient hidden weights, and CNC-machined wheels to ensure the model operates as good as it looks.
Tangent Scale Models want to be very clear. The Southern Railway Gantt Manufacturing Company Bay Window System is not a generic model painted red, like what you may “already have.” This is Tangent-Level execution of bay window caboose details, covering Southern’s Gantt 1969-1974 production. These different body and build options cover multiple eras, paint schemes and modernization programs, all with accurate lighting options plus era and road number specific details.
These cabooses are shipping today! Features for these replicas include:
In order to bring you this project with the level of research required for prototype perfection, Tangent Scale Models needed to measure and photograph five examples of these cabooses! Tangent Scale Models would like to give a big “thank you” to:
Southern (SOU) Road Service “Original 1970” Southern Railway Gantt Manufacturing Company Bay Window Caboose
– Southern Railway (SOU) Road Service “Original 1970” w/ Interior Lights replicates the as-delivered SOU paint scheme and configuration from Gantt Manufacturing. The carbody is painted “Fire Protection Red” with “Yellow Target” steps, railings and axle generator. The roof is accurately unpainted (i.e. silver), but if you look closely, you will notice the red overspray coming up from the sides and onto the roof surface. This overspray is documented in photos and Tangent Scale Models carefully duplicated that look on the model. The black underframe shows off all of that great detail, including center sill pad printing for the reporting marks and car number! This is a sharp paint scheme, no matter how you look at it. The white SOUTHERN lettering fills the left side of the car, and the small data lettering is carefully drawn, including the BLT stencil matching Gantt’s distinctive typestyle. Notice the “high” mounted ACI label, accurate for a Gantt-delivered scheme. It’s these little things that make this scheme look “right” to your eye. This group of cabooses was built without roof-top walkways, and the model’s Stanray roof reflects this accurately. Tucked next to the smokejack is a Motorola “firecracker” antenna. The one side of the caboose body features the battery access door and charging plug. Underneath, the 70-Ton Barber Roller Bearing Generator Caboose Trucks with 33″ standard .110” tread CNC wheels are equipped with an accurate Safety Electric generator. Notice the cut-out area above this style of generator on the carbody. The ends of the caboose feature accurate Gantt-fabricated railings and power brake posts, along with little details like an accurate air release valve and pipe, SOU-style round end reflective target, and retainer valve and pipe on the B-end next to the door. The large body and bay windows allow you to view that full Tangent interior. For lighting, this Tangent Southern model is equipped with “golden” interior lights, mimicking the incandescent bulbs of the real cabooses. A wand is included to operate the lights – easy with no fuss! Tangent Scale Models are offering their Southern Road Service “Original 1970” scheme in 8 numbers. Each car number features accurate month and day data in the BLT and LUB stencils.
This is a hot scheme!
