For those wanting to add a little realism to their operations... MAC Rail is now producing their modern EOT and end of train flags in O Scale! They can be easily added and removed from railroad cars. Their 3D printed items capture the look and feel of various railroad EOT devices seen around North America. Features include solid 3D print for durable handling, model painted to replicate prototype colors, hand painted details, reflective tag, and phosphorescent glow in the dark paint to portray a marker light in low light conditions. They have products that fit both 800 and 740 series Kadee couplers. More products coming in 2021!
