I am guessing that with the automatic destination sign boxes, there is only a limited number of settings. Does anyone know if this is true? And if so, how many different curtins are there and what is on each?
When the 2000s and 2200s were first delivered, they were initially used on the newer (at the time) "expressway" routes only, and as such, were outfitted with the following sign curtain:
/A\ Congress-Milwaukee, Douglas-Milwaukee |B|, all stops Congress-Milwaukee, Douglas-Milwaukee all stops, /A\ Lake-Dan Ryan, Lake-Dan Ryan |B|, and all stops Lake-Ryan. "Not in service" and "Chartered" appeared on all sign curtains on the system as well, while some, but not all, also had a sign that read: "CTA: Spirit of Chicago". In all cases, the "/A" signs were red, the "|B|" signs were green, and the "all stops" signs were black on the Lake-Dan Ryan line, with the word "all stops" appearing as black text on a white background. On the Congress/Douglas lines, the all stops signs were either red (Congress) or green (Douglas), again, with "all stops" in black text on a white background.
A notable exception to the red/green A-B standard was the Ravenswood line, which had yellow /A\ signs, and blue |B| signs. Don't know how or why that happened, but I do remember the 2400s were outfitted with those curtains, since many of them were assigned there during the 80's...
Around the time the 2400s were delivered, the Englewood/Jackson Pk "all-stops" signs were changed to the same red/green standard that existed on the Congress/Douglas lines. By the time the Midway line opened in 1993, and the CTA rapid transit system officially changed to color designations, the newer 3200's had the following sign curtain:
(Brown): Kimball, Loop, Belmont,
(Purple): Linden, Loop, Howard
(Orange): Midway, Loop, Ford City (named for a possible future extension)
(Red): 95th/Dan Ryan, Howard, Roosevelt, Wilson
(Yellow): Skokie
Today, about half of the 2600 series (to about 2950 or so) have the Red, Purple, and Yellow curtains, some may have Brown as well. Also, since the 2400s operate exsclusively on the Green line, I don't know if they've got any additional routes on their curtain. I think the Green, Blue, and now Pink curtains are grouped together, but I'm not sure about that...
