They've been slowly replacing the flip-disc displays on the buses where I live with LEDs and LCD panels which has been such a shame. There is a beautiful mechanical satisfaction to a panel of flip-discs inverting and I genuinely find them easier to read.

The LED / LCD displays are probably lighter (less heavy), and someone figured they can save 0.001 gallons of diesel a year fleet wide if they replace displays.

Net Zero Fatigue is real.

I have a question about those wire ferrules they said they were using:

I occasionally connect wires to terminals, but - I've never used ferrules: I just self-twist the thin strands, push the thing in, and use the lever or tightening screw depending on the terminal's mechanism.

Why would I use a ferrule? Or perhaps, under what circumstances is that advised?

Ferrules often have insulating shells around the base which are good strain relief.

Ferrules also evenly distribute the clamping force and prevent crushing of the strands.

Ferrules solve the problem of having to align the threads every time you re-post them in a terminal block.

Much more likely, I think, the mechanical displays had some maintenance cost which cheap LED displays will not.

The wire will crush over time and the connection will become looser. That will increase the resistance of the connection and in high current applications will cause heating. If you're really unlucky it will cause a fire.

You've confabulated a reason why they replaced them, linked it to initiative then complained about them doing it all in two sentences. A gold medal in mental gymnastics is warranted here!

I remember seeing those at the airport when I was a kid it was fascinating, one of the screens was close to the ground and I got over the chairs just curious how do they flip, now we have the boring soulless LEDs.

They seemed less reliable than LEDs. When they were common here they would always have tens of dots stuck in the wrong position.
