Underground station layouts

State will happen eventually, but it will take a while. It's easily the most difficult for me to do - curved and stacked platforms, very little visible on the surface, and no recent projects with maps of the OL portion. The Blue Line portion does have some renders from the 2006-2011 project, including a decent view of the curve.
I did find a couple of fire maps at State that could help out. The fire maps are located in the Old Statehouse entrance of the station.
 
As requested, Government Center. The former Court Street station area is very speculative, and largely based off a handful of 2014 photos and a later-modified 1903 plan. Most of the former station area is now occupied by the Blue Line tunnel, the roof of which leaves enough room to walk on.View attachment 4827
I don't know if this has been asked before, but is there a link to the Google MyMaps file? It would be nice to see what has been of the whole system so far.

It's still very much a work in progress (and occasionally I do make corrections), so unfortunately I don't share the full file publicly. I do plan to do so when I reach a reasonable state of completion - at least all of the underground stations - and also release it as KML and shapefiles.
 
I was at Haymarket a couple of months ago, there's an emergency exit on the northbound platform near the southern end of the platform. The surface doors are in the same building as the Orange Line lobby. You can see the surface doors on Google Street view, it's a set of red unmarked double doors. I'm not sure how the stairs are positioned, but it is definitely there.
Good catch! I'll see what I can track down; it unfortunately doesn't show on the fire alarm diagram in the station. If anyone knows of plans for the Parcel 7 (Public Market) building that show them, please let me know.

I found this map of the Boston Public Market. To the left of where the Station is labeled there are three doors that lead to 2 staircases. Both must go downstairs since there's a garage above. The image is low quality, I hope you can make out the stairs. I can link the website I got it from if it's too low quality.

Would you mind if I jump in. I was in the area and decided to visit the double door. I am convinced that is indeed an emergency exit for the Orange Line Northbound platform. The sign on top of the double red doors reads "OL-HMT.1N-EE" which I would assume means Orange Line - Haymarket with of course EE meaning Emergency Exit. Of course, unsure of what 1N stands for (possible track number and platform direction, ie Track 1, North side)...

I have been lurking this thread for a while now and noticed talk about State Street. Going through, I noticed that an entrance is not present in any of the maps... the City Hall entrance. This entrance is only open while City Hall is open so commuters are more likely going to see it closed on their commute. Lucky for me, I just so happen to have a large break time recently between shifts and for the first time, explored it. I've been on the surface area so many times and never knew there was an entrance to the subway there...

MBTA State Street - City Hall Exit
Proudly continuing the State tradition of being nondescript and unsigned.
 
I use the City Hall exit quite often, and would say it's actually pretty well marked. The extent to which it might seem sort of hidden lies in it's location at the far end of the Northbound platform, so people may not really notice it if they aren't on one of the lead cars. Nevertheless, there are signs pointing left for City Hall at other spots along the platform. It definitely doesn't have the same use level as the old State House or the Old South Meeting House access points.
 
Question: Has anyone on here look at OpenStreetMap? It's an crowdsourced map that is edited by volunteer editors. The reason I ask is that if you use the Transport Map layer, it does show the underground platforms. May not be 100% accurate but it could be helpful. Here is State Street with where they put the platforms for the Blue and Orange Line.

Ditto, and true, from the platform, but there is no signage on the surface level. I always thought that exit could be served better by a second, wider stairway and escalator to the left side of the fare lobby, which would come out somewhere in the middle of Washington Mall. That would improve traffic flow and make the entrance more visible.
