I'm new to the board. My office is about 2 blocks from the yard in Portsmouth, and I keep an eye on activity here.
As referenced in a couple of other threads, there has been a steady stream of scrap metal going to Grimmel's operation at the state pier all summer. They spot three cars at a time on the track that leads to the Sarah Long Bridge, and unload them onto the pier.
Between the empties from Grimmel, Boise and Highliner, and the regular LPG tanks (not clear if they loaded or unloaded in Newington), the crew was in Portsmouth/Newington for over 8 hours last Thursday. They left with 14 cars, which is the most I've seen on one train in Portsmouth since I was a kid. Here's a video:
Also some photos of the switcher pulling scrap metal hoppers out of the yard, down to Boise to grab a box and center beam, up to Newington to run around them, back to the pier, and spotting the hoppers on the spur for unloading.
