Google thinks today is something called Pi day... but Pi is not 14.3.

(Even if you concede that in Yank land it's 3.14, it won't be the 14 March there for some hours.)

The other qualification is buried right at the bottom... You can't use your credit card if you want a concession ticket (yet). Full fare only.

Uh-oh, this could be a problem. You can touch on with a credit card at the city loop stations, Nth Melb, & Footscray but the ticket will only be valid on the Craigieburn, Upfield, Seymour, and Ballarat lines...

(It'll be ok if generously interpreted by the AOs & station staff)

Exactly what you'd expect. CBTC supervises braking, but it can't judge how slippery the rails are. So it must assume the worst possible co-efficient of friction. The tram has to be driven as if it is the worst possible ice storm - so cautiously braking down hills and approaching intersections.

The safeworking is probably the real killer irrespective of the electrical problems. It's not easy to get trains talking two (or more) different styles of ATO/ATP. The only example I know is Crossrail, and I know that was a nightmare.

Captain wasn't on bridge (arrived just as the critical mistake was made). Only watchkeepers on the bridge were the Chief Mate and a trainee lookout who couldn't be on the helm (wasn't trained on the azimount drives).

@dreadships.bsky.social Preliminary report on the grounding of the Coral Adventurer dropped.

5 am arrival at a place with no navigation aids and needing precision navigation. Ship unexpectedly wasn't following ECDIS course and Chief Mate was hand steering to recover

And turned up *loud* because boomer ears aren't what they used to be.

(TBF the core problem is the tech decision to move to wireless earbuds, because cost and profit, which normalised listening without earbuds/headsets, because cost)

WTF???? Where did this come from?

An excellent post from two perspectives. Apart from giving evidence of ignoring the contribution of women, there is a second aspect.

As an archivist, it's a reminder that records are not the "truth"; at best they reflect the truth of the creator of the record. Records should always be questioned.

Two scientists walk through a cluttered old-fashioned science laboratory.

The female scientist says 
“Analogue instruments! Paper records! Chalk boards! I thought you'd agreed to modernise the laboratory?”

The male scientist replies
“That's what i'm so excited about: we have moved to cloud-based storage for our data!”

They step out onto a balcony. She says:
“Please tell me you haven't built a library zeppelin” 

This is exactly what he has done. It floats across the sky and he adds
“It's got a fax machine!”

A recent purchase was a UK railway atlas that covers the country (except NI) at a consistent 1” to 1 mile scale overlaid onto the ord survey and opening/closure dates

Its interesting to get a feel for the coverage of the countty

The driver didn't see the problem because the many passengers that exited the train had to pass through a gap a mere 2.6m wide between the train and a platform building resulting in congestion. But the driver departed anyway after getting the 'doors closed' indication...

Fundamentally, the problem was that door obstacle detection standard requires doors to detect things >3cm wide, and will not detect things < 1cm wide. A hand is at most 2cm wide - which does not have to be detected and wasn't.

The RAIB didn't comment on the gap in the standard between 1cm and 3cm.

It's not a good report for the operator. *All* of the safeguards - obstacle detection, CCTV, driver checks, platform staff - failed to prevent the trap and drag.

It might have been very severe if a passenger and the station asst hadn't combined to drag the trapped passenger's hand out of the door.

In a new RAIB report on a trap and drag incident. The RSSB has found that passengers do not understand that the "hustle alarm" means stand back.

I'd suggest if the industry calls it a "hustle alarm" it does not, in fact, mean stand back. Despite what the safety bureaucrats might wish to cta.

Paternal: auto mechanic (before dying young from tuberculosis)

Maternal: mining engineer

(For different reasons I think this is why the next gen women in both families had careers, my aunt as a nurse and mum as a science teacher. Unusual for women in the '60s & '70s.)

You mean something like that State south of the border has done on the Warrnambool and Shepparton lines over the last couple of years?

No; path dependency. Hopper wagons were pointless; they couldn't be loaded at the collieries or unloaded at the ports. Any new unloading facility was designed to efficiently handle 4 wheeled simple wagons with end doors because that's all there was...

The other way of getting the wagon high enough to dump into ships was by a ramp, but this had its own costs and problems.

A common method in the UK in the days when coal was outloaded through ports. It meant simple wagons so you didn't need to haul complications (weight) between the mine and the port (the expensive haul per ton/mile). Particularly with 4 wheeled wagons of low capacity.

I think you can assume that it was not complimentary about Angus' performance in the previous government or the election campaign.

Burying it is a move guaranteed to maximise embarassment when it (inevitably) leaks.

Another interesting bit was that the 5, 10, and 20 cent pieces were identical in size and weight to the 6d, shilling, and florin pieces they replaced. So the old and new coins were interchangable and did not need to be replaced all at once.

Barriers removed from platform 3 Caulfield this week. No doubt to reduce the bottleneck changing to from the Metro.

Platform 2 (the other side of the island) retains barriers, but platforms 1 & 3 never had them
