Only too a few people who actually notice them. I hate to break it to you but the average person using the TTC doesn't care about what type of fare gates it is as long as it takes their fare, look at how many different ones we used to have before the current ones. Basically from what people are saying is that the ones in Ottawa and on the crosstown are a newer version of the ones that the TTC installed which in the end doesn't really matter at all or affect the day to day operations in any way whatsoever. This is exactly like the conversation about train horns on the go train cab cars awhile back.
And I hate to break it to you, but the average person using the TTC also doesn't care about the type of rolling stock that runs, or the colour of the vehicles, or the numbering/lettering conventions, or the naming conventions, or the types of announcements and digital signage.
Should we also stop discussing all of these things, too?
Personally, what I don't care to read is people on an urbanist forum (itself a relatively niche subject) shitting on what other details of the city other people find interesting to discuss. The only issue with the discussion about train horns is that it ascribed value to the train using one type of horn over the other. There is
nothing wrong inherently with discussing train horns, or trucks, or doors, or any other part you can name. If the subject doesn't interest you, move on, instead of going on these self righteous screeds.
