The beleaguered G train is finally getting much-needed improvements with the implementation of a modernized signaling system, but this summer, the project could turn into a headache for Greenpoint and its surrounding areas.
In a briefing on Friday, January 12, the agency revealed the next steps for its signal modernization project, which will replace the existing signals with Communications-Based Train Control (CBTC). As part of that implementation, the MTA says drastic service diversions are needed.

One of the upsides I can see: shuttle buses are usually A LOT more reliable and frequent than the decades-old catastrophe called the B62 bus line …
The B62 would be fine if the busses would stop heading out two or three busses at a time, bunched together. And I don’t mean how buses get bunched together because of traffic mid-route, I mean they leave bunched together from the start of their route. I often wait over 30 minutes at the LIC Trader Joes station, heading south, and then have three buses come at once. It’s not only frustrating for riders, waiting in the cold, but also a total waste of MTA resources. How about spreading the buses out a bit for a change?
The issue with running the G to Forest Hills is that Forest Hills is a bad terminus. Its design only allows 20 trains per hour to turn there and it’s already at capacity with the M and R.
Can someone explain why the G train’s total number of cars is less than other subway lines? When F or E trains sometimes get re-routed over the G line, they magically fit with no issues into the G trains stations. And not surprisingly, with more cars, the customers have less likelihood to travel like sardines in a can. Given the increases in G train ridership over the years, what is the reason for keeping the G train unfairly short??
This is so, so, stupid. The capacity of the G line can be increased by 100 percent tomorrow by adding full length trains!
CBTC is NOT NECESSARY HERE!
With this close down they need to put extra cars on the G train so that people are not clutter together and we are not running to catch the damn train that we are paying 2.90 cents for.
Do like I do and stop paying
