Only T dark territory is on the Foxboro game-day trains on the Framingham Secondary, which probably are considered more excursions than regular trains because they only happen for NE Patriots games and other special events at the stadium. All their regular lines are signaled. They are
screwed, utterly screwed, for the PTC deadline because of the hundreds of track miles of old-timey ABS signaling they've done no planning whatsoever to improve. By far the most out-of-compliance northeastern commuter rail system for 12/31/2015. They might even have trouble making 12/31/2020 if an extension is granted.
MNRR is well ahead of the game. If Waterbury is the only one left requiring a big, expensive trenching of new wires and track circuits for the cab signal base that ACSES sits on top of, then they've done damn good. And managed the clock very wisely on this mandate. Waterbury already has $60M earmarked for signals, so funding the rest of the cost is not a backbreaker.
The ACSES transponders themselves aren't a big deal. Cost or construction time. For the Springfield line improvements, it's $8M total for the ACSES install on 60 miles of (to-be) full double-track that uses generic PRR-standard pulse code cab signals (same number of aspects as the NEC). MNRR would be paying the same track-mile rate Hudson, Harlem, New Caanan, completed Danbury, completed Waterbury, and west-of-Hudson. Plus equipment mods for any of the diesels/control cabs and M3/M7's that need ACSES installations, and whatever extra training and centralized support infrastructure are required. But they'll have a lot of that ops stuff worked out and perfected on the New Haven line's ACSES rollout first.
