This is right where I first lived when I moved to the region in 2009! I never new this existed!

Yeah, not enough purity testing — clearly too conservative

Totally left out free transit too

Yeah, I get every vendor with a CCTV solution upselling me on APC functionality with the abundance of edge compute on vehicles these days (even though I don't manage APCs) - I'm not yet fully convinced it's better; waiting to see hard data on that

Makes sense for the M9s to have had APCs spec'd in
October 27, 2025 at 7:17 PM
Yeah, they do have APCs bsky.app/profile/marc...

The weight sensor solution on LIRR and many other heavy rail fleets now (including our Orange and Red Lines) is to get around a lack of or non-functioning APC sensors

Vehicle suspension data isn't available in the same way on bus as it is on trains
Ridership data is up there as one of the most important reporting metrics for funding at various levels and drives a million other planning processes at agencies

In NYC, my observation of equip on fleet is they're using the APC sensors provided by the CAD/AVL vendor, Clever Devices; same as Chicago

Yeah, this is like a black box to people outside of transit - in general, agencies actually have VERY accurate ridership data on bus through the use of dedicated automated pax counter (APC) cameras/sensors on the doors

To derive unpaid, you'd just look at cashflow/pass validation vs APC ridership
October 27, 2025 at 7:06 PM
Yeah, basically all that. Same fittings as Brightline. Direct harsh lighting, etc etc

They're also using an older version of the passenger info system from Televic, who all of them also use, which I've heard only vague bad things about. We're getting their newest product which I think VIA Rail has

Though my understanding is a legacy from when that joint order was going to be multi-levels which just didn't work out, probably for the better especially for accessibility turner-engineering.com/projects/cal...

I mean the Caltrans and IDOT equipment both have those blunted noses to accommodate a destination sign on either end of the trainset

The San Joaquin livery on the cab car www.reddit.com/r/Amtrak/s/M... and the mismatch on the IDOT loco seems to truly be the most egregious part
October 26, 2025 at 8:41 PM
Yes they are
October 26, 2025 at 8:34 PM
But how?

What're your thoughts? Hardware - glare? Screen size? Brightness?

Software - good design? Responsive? Accurate? What happens during disruptions?
