The Mid-Atlantic Railroad Prototype Modelers (MARPM) Meet is one of the premier annual gatherings for railroad prototype modelers in the eastern United States. It brings together model railroaders, railroad historians, photographers, authors, manufacturers, and craftsmen for several days of clinics, model displays, layout tours, operating sessions, vendors, and informal learning.

RPM stands for Railroad Prototype Modelers. An RPM meet is an educational event where model railroaders share techniques, research, and models based on real railroad prototypes. Unlike a train show, the emphasis is on learning, craftsmanship, historical accuracy, and exchanging ideas.

No. While there are vendors and manufacturers, MARPM is primarily a learning event rather than a consumer train show. Attendees come to attend expert presentations, study outstanding models, learn new modeling techniques, meet fellow railroad historians and modelers, and tour exceptional home layouts.

MARPM welcomes beginners, experienced prototype modelers, railroad historians, photographers, structure builders, freight car and locomotive modelers, layout designers, and operations enthusiasts. Everyone interested in prototype-based railroad modeling is welcome.

Not at all. Many attendees come simply to learn. Whether you are building your first freight car or have published modeling articles, you will find clinics and conversations appropriate for every experience level.

MARPM is an independent Railroad Prototype Modelers meet. Many attendees are also members of the National Model Railroad Association, but NMRA membership is not required.

Prototype model railroading focuses on recreating real railroads, equipment, structures, industries, and operations as accurately as practical using historical research and observation.

No. Many attendees model a favorite railroad, while others model specific locations, industries, or time periods.

MARPM welcomes all scales, including N, HO, S, O, Proto:48, Proto:87, narrow gauge, and others.

Absolutely. In-progress models are encouraged because they often generate the most useful discussions about construction techniques, research, and finishing.

No. MARPM is not a contest. Models are displayed to encourage learning, discussion, and inspiration rather than competition.

Clinic topics often include freight car construction, weathering, locomotive detailing, structure modeling, railroad history, operations, industries, prototype research, photography, painting, 3D printing, resin kits, and brass models.

Presenters include nationally recognized authors, historians, master modelers, photographers, railroad employees, and experienced hobbyists.

MARPM welcomes inquiries from knowledgeable modelers interested in sharing their expertise.

Registered attendees may visit some of the finest home model railroads in the Mid-Atlantic region during scheduled open houses.

No. Addresses and directions are provided only to registered attendees shortly before the event.

Operating sessions allow attendees to run trains on highly detailed home layouts using realistic railroad practices such as dispatching, switch lists, waybills, timetables, and prototype operating rules.

Yes. Many layout owners welcome newcomers and provide instruction before the session begins.

Yes. A carefully selected group of manufacturers, publishers, historical societies, and specialty retailers offer products aimed at serious prototype modelers.

Registration is available through the MARPM website before the event.

Yes, but advance registration is recommended because some activities have limited attendance.

MARPM is held near BWI Airport near Baltimore, MD, making it convenient for attendees throughout the eastern United States.

The host hotel offers convenient access to event activities, with additional lodging available nearby.

Yes. Free parking is available for attendees at the host hotel.

Many attendees consider RPM meets the fastest way to improve modeling skills because participants can learn directly from nationally recognized craftsmen while studying hundreds of models up close.

MARPM emphasizes education, prototype research, hands-on modeling, informal discussions, exceptional model displays, home layout tours, operating sessions, and community rather than simply buying trains.

Many experienced hobbyists consider MARPM among the premier Railroad Prototype Modelers meets on the East Coast because of its educational focus, nationally recognized presenters, layout tours, and welcoming community.

A train show focuses primarily on buying and selling model railroad products. An RPM meet focuses on education, prototype research, clinics, model displays, and sharing techniques among modelers.

MARPM offers clinics, model displays, and discussions covering prototype freight car construction, detailing, weathering, and historical research.

MARPM regularly features expert clinics and model displays demonstrating realistic weathering methods for locomotives, freight cars, structures, and scenery.

MARPM brings together nationally recognized modelers, authors, historians, and craftsmen who are eager to share techniques and answer questions.

MARPM is one of the premier annual prototype model railroad events held in the Baltimore, Maryland area.

Yes. Beginners are encouraged to attend, ask questions, and learn from experienced modelers in a welcoming environment.
