Even though classes have started again, I still have too much free time, so I decided to see exactly how much time is lost if you change trains in NHV.
On any given weekday, here's every southbound Amtrak arrival into NHV (excepting #67 which arrives at 12:30 AM and is useless for the purposes of this exercise), with their respective arrivals into NYP and travel time included for reference:
- #2151: Arrives NHV 7:11 AM, Arrives NYP 8:45 AM (94 minutes)
- #141 (from SPG): Arrives NHV 7:28 AM, Arrives NYP 9:20 AM (112 minutes)
- #2153: Arrives NHV 8:15 AM, Arrives NYP 9:40 AM (85 minutes (skips STM))
- #2155 stops at STM but skips over NHV and seems to be the only train that does so.
- #95: Arrives NHV 8:41 AM, Arrives NYP 10:20 AM (99 minutes)
- #495 (from SPG): Arrives NHV 8:35 AM
- #171: Arrives NHV 10:39 AM, Arrives NYP 12:16 PM (97 minutes)
- #2159: Arrives NHV 11:18 AM, Arrives NYP 12:45 PM (87 minutes)
- #93: Arrives NHV 12:09 PM, Arrives NYP 1:50 PM (101 minutes)
- #83 runs instead of #93 on Fridays, but both trains are identical as far as WAS
- #493 (from SPG): Arrives NHV 11:50 AM
- #2163: Arrives NHV 1:18 PM, Arrives NYP 2:45 PM (87 minutes)
- #173: Arrives NHV 1:39 PM, Arrives NYP 3:16 PM (97 minutes)
- #2165: Arrives NHV 2:18 PM, Arrives NYP 3:45 PM (87 minutes)
- #2167: Arrives NHV 3:18 PM, Arrives NYP 4:45 PM (87 minutes)
- #137: Arrives NHV 4:08 PM, Arrives NYP 6:00 PM (112 minutes)
- #55 (from SAB): Arrives NHV 4:30 PM, Arrives NYP 6:24 PM (114 minutes)
- #2171: Arrives NHV 5:18 PM, Arrives NYP 6:40 PM (82 minutes)
- #175: Arrives NHV 5:48 PM, Arrives NYP 7:20 PM (92 minutes)
- #475: Arrives NHV 5:35 PM
- #2173: Arrives NHV 6:38 PM, Arrives NYP 8:05 PM (87 minutes)
- #2175: Arrives NHV 7:29 PM, Arrives NYP 8:55 PM (86 minutes)
- #177: Arrives NHV 8:12 PM, Arrives NYP 9:50 PM (98 minutes)
- #179: Arrives NHV 9:10 PM, Arrives NYP 10:45 PM (95 minutes)
- #479 (from SPG): Arrives NHV 8:50 PM

Red color indicates especially bad connections - ones that have you stuck in NHV for more than 30 minutes, or ones that arrive more than 40 minutes after you would've gotten there had you not switched. #1533 is written in gold because it holds the distinction of actually managing to reach New York
before the Regional you connect to it from, assuming you can make the three-minute transfer.
Having taken the time to compare schedules this way, I have come to the conclusion that #95, #171, or #173 are the trains you want to be on if you plan on switching - with #171 being the best one to get on from BOS and #95 being the best one to get on from anywhere in Rhode Island.
Fare-wise, it costs less to transfer at NHV than it would to go direct to NYP (and depending on when and where you book, perhaps significantly less), there's plenty of options that have you spending little to no time cooling your heels in NHV, thanks in part to Metro-North's tendency to spitefully run their trains in front of Amtrak's, for the most part they aren't particularly slower, and you get to avoid the perpetual shitshow that is NYP.
I mean, sure, riding into NHV from anywhere west of Newark just to double back is kind of ridiculous, but if you're coming in from NHV or anywhere east of it, switching trains isn't a bad idea at all if you go in planning to do it - and for the most part, if you're coming in from the north (HFD or SPG), it's an absolute no-brainer since with only two exceptions, you'll need to switch trains anyway, and switching off of the direct Regional out of SPG actually puts you in New York faster than staying on it would.
