3M Diamond Grade 983RR Conspicuity Tape -  3M^® 983 RR reflective tape is FRA approved and carries the FRA logo.  It is specifically designed to enhance the visibility of railroad cars and locomotives (see specifications [pdf]).  It is a 3M Diamond Grade retro-reflective tape that uses micro-prismatic lenses encased in a clear resin to reflect light and has an aggressive tack adhesive to enable it to stick to a variety of surfaces.  Large rolls can be ordered either continuous or kiss-cut into standard 18" application lengths (100 per 50-yd roll).  Applied properly, this extremely tough, durable tape is warranted by 3M^® for a life of ten years in outdoor conditions.  3M 983RR railcar conspicuity tape can also be applied to school buses, industrial equipment, bollards and any other items where night time visibility is a requirement.  FRA tape is stiff, but flexible enough to wrap around diameters as small as 4-inches.  A complete 3M^® product description and a video of application instructions can be seen at the following link:  3M^® 983RR Railcar Conspicuity Tape.
