Prototype History: Developed in the late 1960's for rolling stock identification, the ACI plates became a common sight throughout the 1970's and beyond. Ultimately, the program failed due to dirty, unreadable railcars and more sophisticated reading systems (the modern AEI tag). Model Description: Now you can quickly add ACI plates to your 1970's+ rolling stock where appropriate. This package contains 10 ACI plates - enough for five pieces of rolling stock!
