Eastern Railroad Discussion > A nice surprise on CSX's Capital Sub.

CSX train L-125, a local, is W/B entering CSX's Capital Sub on track one at MP BAA 6.9. A nice surprise having an unusual leader, SD70MAC-4582, on the point. 4:23PM on 3-20-23 in St. Denis, MD.

Nice catch; I certainly recognize that view.

What is the meaning of the "D" marker?
 

I believe it signifies "Departure" from the MARC station for their trains.

It's a Distant Signal Marker.

It appears that there is a crossover right after the signal.  Wouldn't that be a home signal for the interlocking?   I am unfamiliar with this territory, perhaps somebody can explain.

Under CSX signal rules...if it has any marker it is an Intermediate signal....how that works with a crossover I don't know...but perhaps it is hand throw. I'm not qualified up there so....
