Kinda makes u think why not run the G to Queens Plaza instead of Court Square

It does, except for this weekend, the (G) is not running at all and (G) stations will be closed.

Then next week (Monday January 18th to Friday January 22d 10:30PM to 5:00AM) (G) stations are open but the (G) runs in two sections: 71st Avenue-Continental Avenue to Bedford-Nostrand Avenues and Bedford-Nostrand Avenues to Church Avenue as work along the Brooklyn-Queens Crosstown Line continues..

The Forest Hills - Bedford Nostrand Avenues section operates every Half-Hour:

Northbound (G):
:19 and :49 after the hour

Southbound (G)
:35 and :05 after the hour

Apparently, Bedford-Nostrand Aveues - Kensington section is normal every twenty minutes.

The R train once again running QB local by itself on weekends, what a surprise(sarcastic)

Sounds like the permanent, near future.

I rode the G shuttle bus....i was impressed....granted the signage at Hoyt-Schermerhorn wasnt the greatest, but i caught on....i got on the shuttle bus at 1:23am and got off the bus at 1:52, i thought that was good

I got on the G shuttle bus on Broadway at around 4:40 and I got to Queens Plaza at around 5. It was pretty fast. However, I heard that the people I was with got on an artic right after that, which took almost an hour to get to Jay.

No fun tryin to navigate an artic through Greenpoint and Bed Stuy and Fort Greene lol

They should just use RTS and hybrids and orions for shuttle bus ops like this where tight streets are involved

I rode the G shuttle bus last night. It was a smooth ride from Jay Street to Washington Ave on the NG.

Maybe they're secretly trial testing replacing the G with a bus route.

This weekend the G shuttle bus will run between Jay St-Boro Hall stop to 21 Street-Queensbridge stop due to the E train running via 63 Street. Stops on 53rd Street will be closed during the weekend. This weekend only the R train will be stopping at Queens Plaza during daytime hours only and during late nights the station will be closed. Hope you plan extra time this weekend if you take the G train and planning to go to Queens.

Does this mean that the E will run entirely local into Manhattan? And will it run along 8 Av until W. 4 St or will it run along 6 Av after 5 Av-53 St like a few months back? I didn't receive any emails yet so I hope service is normal

I think the (E) is terminating at 34th St-6th Av because I saw an advisory stating that the (D) is running local along 6th Avenue. As for Queens, I think the (E) is still running express with the (F).

This advisory will last until February 18

Shutting down an entire subway line is bullcrap.

Well, the MTA calaims they're replacing track along the (G) line

Yeah sure they are. Yup

They tweet photos of the work they perform. It's a nice addition and looks legit to me. In regards to shutting a line to replace track, certainly that section of the line needs to be shut at minimum and then they perform other work along the line as well, so shutting down the line makes sense as long as they get the maximum benefit of the work while the line is out.

Yeah I guess that's true. Its not like they're shutting down a major line like Lex or 7 Av in Manhattan or QB or B'way. They need to quit with the 7 train though...sheesh.

The 7 is now going through what the L went through.

The thing with the 7 though is that they have no other time to do this kind of work, since the spring-fall months bring in the baseball season and no major work like this can be done without disrupting the commutes of stadium-goers. They don't have a choice.

with all these alternatives, the MTA doesnt need the (G) train. the (G) is like a shuttle but with many stops! now thats ridiculous. that line is a waste of money and Cars. (its only 6 full R46 trainset and a half R46 train set out of the yard). i think the (G) should be eliminated...also the line doesnt have high ridership.

I dont know, I heard the G is packed during rush hours.

By that logic, we shoudn't have any shuttles. The G is an important link between Bed-Stuy/Williamsbug and Downtown Brooklyn, as well north to Long Island City. Buses coming from those areas would be packed without the G train. It would be like near 3rd Avenue in the Bronx, where eliminating the 8 train causes buses to be crowded coming from this area to other subway lines.

Which 8 train? And YES the G needs to be GONE! Its a phantom train to begin with and it seems to have NO ridership. I couldn't picture it as being packed during rush hrs. Never.
