BD Signage Sucked ... even in '66!
Joe -- I'm old enough to comment on subway signage issues. I know you're a fan of the old BD signs in that Leave-it-to-Beaver-ish '50s font, but the truth is that even those signs sucked. When it comes to signage, the TTC could never get it right. I know this post is about the current Y diversion, but let me explain some issues related to the original routing in '66, the signage they used back then, and the endless confusion it caused for passengers during the line's first week ...
When the BD subway opened, I remember that the maps in all the cars showed the YU and BD lines as *SEPARATE* routes, even though BD operated as integrated branches of YU for the first few months. Once you were in the system, there was no indication of the exact routing of any train in any station. This was well-advertised in all the papers the day before, but there were no system maps once you were inside a station, and the trains themselves showed separate lines (probably because the TTC knew that they would not continue the service pattern after 6 months and didn't want to bother replacing them all later on).
Even worse, trains bound for the Y from BD were signed EGLINTON, but the overhead station signs would flip to say DOWNTOWN. This caused confusion, so the trains were later changed to display EGLINTON VIA DOWNTOWN. Of course, this sign was wrong after the train passed downtown and was heading north on Yonge, but if you're the TTC, who cares?
Next ... at the Keele and Woodbine terminals, there were two display signs at the mezzanine levels that would say ...
PLATFORM 1 ... either DOWNTOWN or KEELE/WOODBINE
PLATFORM 2 ... same
BUT, if you were heading to a station before the Y, you couldn't tell which train was leaving next (either train would take you to your destination but you had to guess -- remember, we're on the mezzanine here so we can't see the trains). To solve this problem, later on the signs at Warden and Islington were changed so that they could read ...
1ST TRAIN ... WARDEN ->
2ND TRAIN ... <- DOWNTOWN
but by then, integration was dropped. Also, at the Keele/Woodbine terminals the NEXT TRAIN overhead signs were revised to say THIS TRAIN because people thought the destination applied to the next train, and not the one that was sitting at the platform.
Bay and St. George had a similar problem. There were lightable arrows on directional signs to tell passengers which platform would receive the next eastbound train (at Bay) or westbound train (at St. George), since the arrivals usually, but not always, alternated between levels, but often the displays were blank for extended periods of time when no trains were in the vicinity of the station -- so we had to wait on the upper platform and keep checking the display.
I also rode the last diversion in '07, and, compared to '66, I thought it was signed quite well ... a breeze. Let's hope it goes smoothly this weekend.
Oh yeah, delays. We had tons of them in the early days, but not in the morning as I recall. Morning ran fine, afternoon was a disaster as the headways changed and more trains were fed into the system from Greenwood. At least that's how I remember it.
