Other than the 7k cars and many of the 6K cars.. most of the interior next stop signs don't work in trains. Why is this?
For a while I thought it was because of the "bellying" of the 1k cars and mixing different series together in one train. But on several occasions I have been on a train that was entirely made up of one series (3K or 5K) and the interior next stop signs would only say the color of the line like "Red" or "Blue" but the next stops would not show. The 6k cars are the only exception.
What is the reason for this? These cars have been on the tracks for years and they still can't get the software to work?
