While passing through Fostoria, the west-facing signal on CSX Track 1 (north of two) had an indication of yellow over blinking green over red. It is the first time I have ever seen this, and I am wondering what it means. For what it is worth, CSX Track 2 was blocked at the time with a stray caboose while some switching was taking place nearby. I was on the company clock, so I did not have time to explore any other movements. However, the train that was going east through said signal on Track 1 did proceed completely through town (a long train of coal cars with UP power).
Clear to Limited
It means the next signal after that one is most likely displaying a limited to _____ indication. The crew has to have the train down to limited speed before passing the next signal.
And here I thought it was the traffic light computer is malfunctioning.
approtch limited…prossed apporching next signal not exceeding limited speed…
