Yeah, CSX isn't paying for it. I think Maryland is.
What's ironic is that 20 years ago, there was a set of intermediates there...and I hope like crap they call the interlocking Halpine as an homage to the original signal there, and NOT name it after some manager or official (which they sometimes have a history of doing).
Crossovers are also being installed at Tuscarora, and a new defect detector has been built at Wards to replace the one at Clopper, where supposedly another set of crossovers will be installed. It's going to be lovely having abosolutes at Clopper...nothing like having a STOP signal on the edge of a cliff headed westbound. I'd really like to see the two to one westbound crossover at PEPCO completed to include a one-to-two westbound. It's a pain having to zig-zag around one to the spur especially on a 40+ car D765 that the dispatcher has run you west on one, and now you've got to pull through, shove back, pull ahead, then shove onto the spur.
