If you get a rent-a-cop who wants to give you grief about not being a ticketed passenger...you have a ticket. (Said rent-a-cops are prevalent on the New Haven line. West Haven is a prime example.)
2.) See above.
3.) Good luck finding a railfan window on the New Haven line...I would *not* stand at the door to the cab on any equipment, especially the new ones that don't have a RFW...odds are pretty good you'll be chased away. If you're on the older MU's and the "restricted area" gate is up - respect it, the cabs on those are like closets. Not a good idea to be blocking that door if God forbid something happens and that engineer needs to bail out of the cab to avoid some sort of object, etc.
Although photography is allowed, there are no guarantees you won't get hassled. In general if you stay out of the way in publicly accessible areas and aren't being annoying, you'll be left alone for the most part.
I was gonna add "Always carry a copy of the memo from the MTA (MTA police?) on photography, but the links are gone, sadly. Bummer, as that was a VERY important thing to have, IMO. Having the memo doesn't guarantee hassle-free photography/videography*, but it is still good to have.
* Man, that brings back 'fond' memories of a 2009 incident where I was getting some video at Mamaroneck. One time, as a train was leaving the station, the engineer saw me, and decided to confront me on the matter. I was showing him the memo, and everything, which eventually turned into him threatening to call the DHS on me. I (politely) called his bluff. I got the entirety of the incident on video, and put on Youtube a few days later.
Not even the Mamaroneck PD would waste a lot of resources on such a matter it seems. Less than a year after the prior incident, they met up with me at the Rockland Ave overpass after someone made a call in to them, and the experience was very different - very calm, understood I was acting legally, and even recommended some great places to get photos from.
