O DPM Street/Dock Level Arched Entry (2) by Woodland Scenics

DPM's O Scale Modular System plastic wall sections make it fun and easy to create buildings of any size, shape or height. Architectural details are molded in place. Use plastic model cement to assemble your building. All wall sections are 4 1/8 inches wide. Build large or small O scale buildings (whatever you need) with highly detailed modular parts. It's easy to create buildings designed especially for your layout. Build second and third stories by stacking the desired wall sections up. Top the buildings with cornices when you reach the height you want. Two identical wall sections with pilasters, plus clear window material where needed.
