GATORFOAM® Rides Rails Of Success As Rigid-Yet-Lightweight Substrate For Model Railroading

Dave Myers cut his teeth, so to speak, on Gatorfoam® graphic display board as an educational-TV set designer in Hagerstown, Md., in the ’70s, when he used the industry’s leading heavy-duty foam board to create cut-out letters and 3-D props. Myers later opened his own commercial sign shop – DMG Studios in Hagerstown – a business in which he often turned to Gatorfoam as his rigid substrate of choice for sign-making, including such memorable point-of-purchase displays as 4-foot tall milk cartons for a local dairy.

964d0526f5c3e389ebfd3431b0b4ca78_f181Today, as a semi-retired sign-maker in Waterbury Center, Vt., Myers has turned his professional appreciation of Gatorfoam into a product that supports his hobbyist passion for model railroading. He’s modeled The Mid-Atlantic & New England (the MANE) railway line running from Maryland to New England as well as the Mill Creek Coke & Coal Tipple No. 2 and other craftsman model kits. These extensive models occupy a second-story 18-foot by 29-foot room built within the exterior walls of the 1820s barn located on Myers’ property.

“As I built my railroads, I always reached for Gatorfoam as my modeling substrate,” said Myers, who is a member of the National Model Railroad Association. “I immediately started using it for bases and expanded from there to sub-roadbed, back drops and module surfaces. I knew from using it in the sign business that it held up extremely well, machined great, and took paint and stains without warping.”

While Myers – who describes Gatorfoam as “bulletproof yet lightweight” – long has been a proponent of the rigid substrate in model railroading, he’s had to educate his fellow railroaders about its benefits over much heavier plywood or lighter-duty foam boards.

Myers’ original product offering at model railroad shows consisted of trees that he had modeled and then displayed mounted on Gatorfoam.

“I wasn’t selling any trees; instead, I was re-selling Gatorfoam at the shows,” said Myers.

Myers buys large Gatorfoam sheets in the 3/16-inch and ½-inch thicknesses from 3A Composites’ distributor Harbor Sales ( in Sudlersville, Md., and cuts them down to fit the most popular railroad modeling projects.

Myers offers custom-cut Gatorfoam pieces for modeling in both the 3/16-inch and 1/2-inch thicknesses in sizes ranging from 8-by-12 inches to 32-by-48 inches in primarily the Bright White color and to a lesser extent in the Natural and Black colors. He also sells Gatorfoam backdrop kits that include a ½-inch thick Gatorfoam base and a 3/16-inch thick back section in three sizes as well as the screws needed for assembly. Models or scenery can be mounted on the backdrops.

“With a Gatorfoam backdrop, you know it’s not going to twist and that moisture won’t affect it,” said Myers.

In addition to selling Gatorfoam pieces for modeling, Myers freely distributes printed technique sheets for creating everything from

model bases to driveways, streets and roads, and concrete from Gatorfoam. He also provides tip sheets for safely cutting large Gatorfoam sheets and irregular shapes from the rigid substrate as well as for creating Gatorfoam module tops.

“I asked my parents if we could leave the train set up all year in the basement,” recalled Myers. “I’d design buildings out of cardboard and shoe boxes. What I really saw was a three-dimensional piece of art. Since then, discovering Gatorfoam has been a real boon to me.”
