The Venn diagram of urban density and average household GHG emissions is pretty much a circle. Interesting study on “Mapping household GHG emissions in the Greater Golden Horseshoe” from the University of Toronto School of Cities schoolofcities.utoronto.ca/mapping-hous...

It's a little bit different because I don't imagine there's pressure w/in military units for high performers to Go Elsewhere, whereas in liberal shuls more observant folks often feel marginalized+pushed out by other people's insecurities+unwillingness to step up to participate. But really parallel.

Granted that "segregating into a 'serious' minyan" is something I have been guilty of myself

Totally random connection, but this is shockingly similar to the effect in left-of-Orthodox American Judaism where a huge % of people who're remotely interested in serious practice/learning gets pressured into being a rabbi or Jewish educator--& many others self-segregate into "serious" minyanim.

usual rates of death and wounding, and so erode more quickly than the
general mass of the force.7
This selection-destruction cycle means that a force with too high a proportion of elites—an army with too many special forces units, a navy that
diverts too many of its most aggressive junior commanders into the submarine arm, or an air force (like that of imperial Japan) with aircrew standards
that prove unsustainable over a long war—can actually damage its adaptive potential. Such a force experiences a brain drain, where individuals
who would have been leaders in regular units (and would likely have
survived to spread their knowledge to others) are instead segregated into
subgroups where, even if they survive, their talents are lost to the wider
force. Meanwhile, major combat formations can cease to be much more
than feeders for specialized units, providing the recruiting base for elite
forces that increasingly usurp normal combat roles, exacerbating both the
brain drain and the selection-destruction cycle that Beaumont describes.

FRA emergency order about SEPTA's Silverline IV fleet. Doesn't order them immediately out of service but mandates various training and inspection changes and makes it clear this is a Very Big Deal www.federalregister.gov/public-inspe...

There is exactly one way to rapidly cut pollution at scale, save money both at the govt and household level, and do it without federal help.

The best fastest thing to do on climate is to just make cities safer for walking and biking. That's it.

Every climate person should be working on this.

City Hall: Experts at King’s College London estimated that, from when the Mayor came into office in 2016, without additional action it would take 193 years for London to meet legal limits. It has been achieved in nine years.

This C&NW unit led an interesting life, starting off as an FT, being rebuilt into an F9M, and pulling both intercity and commuter trains in addition to freight. www.railpictures.net/photo/610041/

I've got one Wabash geep! Might swap the DCC-equipped chassis to something I'll run more often though.

Fun, pretty new layout additions that wouldn't have run together in real life: a C&NW FP-9 and a Milwaukee Road Super Dome

Probably the quote that most sticks with me from my readings in rail planning is this one, “we concluded that increasing operating performance and achieving high-speed operation would mean using electric or diesel railcars with power distributed along the cars.”

Both building owners and agencies here would have massive headaches trying to deal with respective alterations. SEPTA doesn't even share trolley poles with city utilities beyond small signs

Sandy Johnston @sandypsj.bsky.social · 9d

Have always wondered why we don't do this more these days. Gotta assume it's mostly to avoid complexity of dealing with all the land/building owners.

Marco Chitti @chittimarco.bsky.social · 10d

One thing I really liked of Helsinki's trams is that even in brand-new neighbourhoods, they keep hanging the wires as well as streetlights to buildings "the old way" whenever possible.

It makes for a much less cluttered urban environment and less stuff on the sidewalk.

!! Is Addison, the village, named after the doctor or the street?

Sandy Johnston @sandypsj.bsky.social · 13d

Indeed! And it's so easy for cities to target industrial areas for redevelopment, because it's the easy path and we don't have industrial/freight policy in any real way...but it's often a dodge around the hard battles of densification in res areas. But eventually you run out of industrial zones!

Sandy Johnston @sandypsj.bsky.social · 13d

Huh, I'm not aware of specific instances similar to this one but it's not uncommon for railroads to (sometimes rightly) fear that neighborhood transitions to be less industrial endanger their operations. How reasonable that is is probably super contextual.
