I have a question about that. I am inferring, following the Chicago rear-ender involving the Amtrak Pere Marquette on NS trackage, and the engineer's statement that he confused the NS red-over-yellow with Medium-Approach, that on CSX the aspects and indications are as follows: Red-over-green = Medium-Clear; red-over-yellow = Medium-Approach; Red-over-lunar = Restricting. Is that correct? And if so, has CSX used lunar for Restricting for a long time (apart from B&O color-position), or is it something recent? (And can Slow-Approach be displayed on a high signal with less than 3 heads?)
As far as the Amtrak wreck the engineer confused the signal and the other engineer who was on the head-end argued with him that it was a Restricting. Unfortunately she failed "To take action" by putting the train in Emergency until they saw the train.
As for Red over Green, it would be Medium Clear, unless it were a dwarf, then it would be Slow Clear....but it the Green was flashing it would be "Limited Clear", but if the green was solid and Red flashing it would make it Medium Clear. Red over Yellow would be Restricting. Yellow over Red would be Slow Approach but if the Red was flashing it would be Medium Approach. Of course this is on former Con-Rail territory because they are basically NORAC signals. When I was on CSXT I only saw one Lunar signal for Restricting and that was only changed a few years ago.
