|Electronic destination sign programs, just like rollsigns, are historic in nature. They can
contain routes or route destinations that can be updated, extended, or discontinued. They
offer a glimpse in time of a system's route history based on the programming date of the sign.
These electronic sign listings are based off confirmed research through a system's electronic sign memory
chips, from program lists provided by the system, or from actual electronic sign programs provided on disk.
To see the program list for each system, based on its programming date, click on a logo icon below.
