Slight realignment of NS Fort Wayne Line and Bridge over Allegheny River; take note of slight difference in background imagery alignment between Bing and PEMA imagery

Realigned NS Pittsburgh/FW Line Allegheny River bridge

Slight realignment of small section of SWP Radebaugh sub/Southwest Industrial track

Added RADE interlocking (milepost PT 325.0) and realigned small section of surrounding track; did not add signals (bridge on west end, 3 masts on south end with SW Industrial Track)

Fixed bad alignment of Conemaugh Line and short siding between West Leechburg and Kitski Junction; also marked other siding in West Leechburg as disused on account of switch being removed.

Realigned and added more nodes to the previously badly drawn section of the Conemaugh Line for the three curves east of Avonmore; also added a bridge over Long Run

Updated Conpit Junction: fixed crossovers, added and standardized signals and switches, extended service road, standardized rail tags

Added more nodes and moved present ones to better curve B-Line from Balls Ford Road west to junction with Washington District in Manassas. Added Vulcan Materials industrial spur and yard.

MARC section of the yard at Ivy City, built around 2013-14. Not sure why it hasn't been added yet. Seems to store about 4-5 consists (MARC only) at a time. Not electrified, so likely daytime Brunswick/Camden storage for those that are not used on Penn.

TUSCARORA interlocking on CSX Metropolitan Subdivision, built ~2014 as part of "a signaling and capacity expansion project....to bribe CSX into allowing for the future expansion of MARC Brunswick Line services", per to prr4ever blog.

The rest of the (not really) new MONTROSE Interlocking on the Met Sub, added sometime around/shortly before 2015.

MONTROSE Interlocking on Met Sub added sometime around 2015, according to https://www.trainorders.com/discussion/read.php?2,3754033. Not many clear sources but it definitely exists.
