The one thing fascinating thing I've noticed from the angry people on Facebook ranting about the LRT plans is that a lot of people seem to genuinely like the HSR. Not that Hamilton is some transit-loving paradise, I think many people have a positive nostalgic view of using the bus when they were a kid (and haven't touched in many years, but are happy to tell you it's "perfecly fine as it is!"), but where I grew up, in York Region, the bus was definitely seen as the "loser limo" for the desperate and did not really have any respect.
I’m obviously a bit late, but this is fairly easy to explain. The HSR is a long-standing institution in the City of Hamilton, that has deep roots and a history equivalent to the TTC. It also was probably, verifiably, a much better service in the past. I mean, it’s the Hamilton Street
Railway. So that covers the nostalgia aspect, I think.
Besides also being quite dense, the other half is that Hamilton is
predominately ( not exclusively) a working class city, and always has been. This correlates to more transit usage.
There are parts of Hamilton which ‘have the means’ to look down on the HSR because it has fallen behind its peers (first the TTC, but now also the 905 and beyond). Ancasterites for instance are by no means dependent on transit, but they also do not get levels of service that could shift perception.
So more on-topic is, much of the city (exempt the lower city) has underwhelming frequencies and absolutely abysmal stop spacing that hampers using HSR if you have a choice. Many do not. However, perhaps the easiest fix is addressing the ~2x too many stops. Routes can take far longer than any conventional suburban routes I’ve used elsewhere.
Express routes are a good fix, but we are nowhere near our peers on these, as it requires resources that are only now starting to appear.
