What does railroad fabric mean?
Railroad fabric refers to a type of upholstery fabric that is woven horizontally instead of vertically. It's the way a fabric, particularly a pattern or stripe, is milled. Usually, fabric patterns run “up the roll,” meaning the pattern flows from top to bottom, parallel with the selvage edges. On a fabric that is railroaded, the pattern runs across the roll from selvage to selvage. In contrast, most fabrics are woven with the pattern running vertically, or up and down.
