MOUNT VICTORIA, 127km from Central, is a beautiful station cut into sandstone, serving a town at the top of the Blue Mountains. It has two platforms accessed by a footbridge, but no lift. The station features a range of grand old buildings that show its former importance on the line. (1/4)

RTD bans ads covering windows of metro Denver buses and trains
The prohibition means losing revenue at a time when agency officials are grappling with financial constraints.

What a shocker of a trackwork weekend, no trains thru the city except T4. How's that for planning!
City Circle closed. T2,T3 end at Strathfield. T8 ends at Sydenham or Central (map's wrong!)
T1,T9 closed Central-Wynyard.
Metro Closed.
Plus the new bridge at Sydenham is closed for some reason!

our govt wants to spend 327 times more on a single road ($18b) than they are currently spending yearly on all of basic science in new zealand ($55m) #nzpol
The Northern Expressway we were told would cost $10 billion is now priced at $18 billion, or six times the Cook Strait crossing we were told was unaffordable. This is fantasy stuff. www.nzherald.co.nz/northern-adv...

Sydney's bus branding is dull and really undersells how essential they are.

Sydney's buses move more people than Melb's trains. But you wouldn't know it.

Leaving it to the Coroner to do the pill testing seems sub-optimal
A young person died just days after the LNP make pill testing illegal.
There’s a good chance that if they could have had these pills tested, they’d be with us all today.

Some great discussion below here
I spent a few years writing profiles of Australians from all different walks of life, which forced me to think about this to some extent. I have no good answers but the sense I have is that colonial Australians don't really associate themselves with, or engage with place.
A hypothesis: it’s partly that we’re largely unable to talk about Australian cities non-ironically, regardless of medium. You can’t sing about Melbourne the way Fontaines DC sing about Dublin, so we get the Smith Street Band.

Further details of TfNSW’s future plans for Sydney’s rail network have leaked (link in replies). These don’t have government approval yet, let alone funding. But they give a good indication of the next “cab off the rank”.
