Activities at MARPM
The Mid-Atlantic Railroad Prototype Modelers (MARPM) is four days of camaraderie and sharing—knowledge, techniques, stories, and experience.
The Show
Typically Thursday is the day for operating sessions. On Friday as many as 20 outstanding home layouts throughout Northern Virginia, Annapolis, Washington, DC suburbs, and Baltimore are open only to MARPM attendees. Saturday and Sunday the event hotel opens. Participants display their models, attend clinics, interact with vendors, and await the anticipated raffle drawing.


Clinics
Outstanding modelers deliver more than 30 clinics on topics ranging from prototype rolling stock to layout techniques, weathering, 3D printing, operations, railroad history, and scratchbuilding.

Displays
Bring your models! A highlight of MARPM is always the locomotive, rolling stock, structure, and diorama models brought by attendees. Space is free, first come, first served.

Open Houses
Visit renowned model railroads throughout the region. Addresses are emailed to registered attendees in advance.

Operating Sessions
Operating sessions are a key part of MARPM. Space is limited: available sessions will be listed here.
