After the Queens Blvd locals (M/R) terminate in Forest Hills, they loop around through Jamaica Yard, meaning non-revenue track. Stragglers being asked to alight is a common sight.

> Usually, if a non-looping subways hit EOL, there will be a sweep and a rest period.

Generally this is a short rest period, ~ 10-15 minutes max during peak times and 30 minutes max otherwise. Nobody's kicking you off, you can just wait until the train starts back the other way.

It's also generally the least busy part of the line.

The second greatest problem on NYC's subway for people who wish to "live" there (after rush hours) has to be the light. The fluorescent is unavoidable.

The south end of the Lexington Ave line is a loop.

Is it? I’m not sure I see that. The 4,5,6 doesn’t appear to loop anywhere as far as I can tell, nor do any of the NYC lines.

It is a loop, but passengers are not allowed on that segment. If you manage to stay on the car, you also get to take a quick peek at an abandoned station.

Ahhh, yea, in that case I believe the bottom of the 1 is as well in the Financial District. Very small loop. Always interesting to get on there because I think it's the tightest curve I've found and the trains probably at a good 6 or 7 degree tilt there. Neat stuff.
