## What is Greenline?

Greenline displays the real-time arrival predictions and locations for all MBTA Green Line trains.

Greenline has a sleek and intuitive design. When you first open the app, it will find the nearest station, tell you how many minutes until the next train arrives, and show you where the train is currently located.

While you're waiting for your train, you can play with the interactive map and watch as Green Line trains move across Boston.

Meeting a friend? Let your friends know where you are by sharing you're train so they can track you in the app.

Greenline is powered by real-time vehicle prediction and location data provided by the MBTA.

### 3/5 — Update for new Green Line extensions

*2024-08-23, version 3.0*

Needs to be updated for new Green Line extensions

### 3/5 — Works…   Sort of

*2022-01-03*

Only works if the train operators have turned on their gps transponders.  App needs to be updated to support new B line stops,  Amory St and revised Babcock.  BU West, Pleasant St and St. Paul Street stops no longer exist.

### 2/5 — Used to be great

*2019-04-26, version 2.0*

Doesn't work anymore. Not sure if the developer stopped supporting it or if it's a bug.

### 4/5 — Was great, stopped working

*2019-01-12*

Update please, this app no longer functions! It was great to know where the ever unreliable B line was... but now we are back to being in the dark.

Will change rating if updated

Update: seems to be working again but still in need of some updating. Has not had one in a long time

### 5/5 — Extremely well done

*2018-12-23*

I’ve been looking for something like this for a long time and this is absolutely perfect. Kudos to the developer

### 3/5 — Not enough updates, not accurate enough

*2018-11-28*

The app keeps crashing. Often times it’ll show the next terrain coming in 12 minutes and then all of a sudden I’ve missed three trains within the next 4 minutes. It doesn’t have frequent enough updates and the timings just aren’t accurate. If it says 1 minute til arrival I go outside and wait in the cold for at least 3. Would not use if I can find a better one soon.

### 3/5 — Usually pretty accurate time but missing stops

*2018-11-15*

There’s no Government Center stop here but it usually is pretty accurate with the timing except for a few missing trains in the system.

### 1/5 — Was great, needs updating

*2018-11-04*

App won’t load. Was a great app at one time even to the point of being used by Green Line inspectors. But hasn’t worked in a while. I’ll update my rating if the app gets updated.

### 2/5 — Does this work anymore?

*2018-08-25, version 2.0*

Worked great for a while. Suddenly stopped working. Just refreshes over and over. Is this app dead?

### 1/5 — No longer works

*2018-08-20*

Was great until the most recent update. Now it just spins for about five minutes and then gives an error message that data is not in the correct format.

Update: seems they had it fixed for a short while but it’s back to just spinning endlessly, with not even an error message now. Useless.
