Reweigh, Lube & Other Goodies for NP Hopper & Ballast Cars: Beginner and intermediate NP modelers – rejoice! This inexpensive decal sheet makes it SUPER EASY to upgrade your Ready-to-Run NP hopper models with all the little pieces of lettering and artwork needed to make the model look like the prototype. We have targeted these RTR cars for updates – Atlas Hart ballast, Intermountain and Atlas alternative two-bay, Intermountain/Tichy USRA two-bay, TRIX three-bay, and Bowser/Bachman 3-bay. The two sheets include enough material for dozens of cars, and also includes additional road numbers so you can grow your fleet beyond what the manufacturer offered. Cut them out and slap them on – the Microscale sheet makes it very simple to apply and align the correct data for your era. The sheet also includes chalk marks and a few other hard-to-collect lettering for hoppers. Buy two, they are cheap!
