Riding a renovated train right now. It is dirty both inside and outside, paint is peeling everywhere. If I wasn’t a tube fan, I would have guessed that the refurbishement was done at least 15 years ago.
So I guess it’s the same quality as the Bakerloo line renovations. But thinking about it a renovated Bakerloo line just has led lights grab poles added by does and wheelchair space added in 2nd carriage. I have seen a few videos with dot matrix added to the train but haven’t seen it in real life. More or less the same has been done to renovated central line trains add the motor and dot matrix display, but we were made to think it was a big thing.

Whilst focus today has been on regional transport improvements, DfT has sneaked out RVAR exception updates for Central line and Waterloo & City



Basically TfL want an extra 7 years exemption extension to 2032, originally applied for in 2018 expiring 2025, enable them to complete CLIP work by 2024. However because they have failed to complete the work during exemption period, now requesting massive extension. Rather cheekily the reason given was Covid pandemic, and train deterioration (although why that justifies a 7 year extension is beyond me, as pandemic delays generally taken as 15-18 months).
Some items they are requesting indefinite exemption, because it would be difficult and cost money to modify to comply.

SEVEN more years to finish the CLIP programme? By the time they finish, the 92s will be ready for the scrapyard!

At least that means the dc motors are here to stay for longer as they suit the train much better imo.

’Suit’ in what way..?
The incredibly special and unreliable chopper sync fibre optics?
The brushes that eat themselves?
The old gearboxes that vibrate themselves to pieces?
The special bolts that are around £780 each when I last checked?
The lovely lovely flashovers?

They just suit the aesthetics much better. Nothing logical. The ac motors though practical and needed spoil the retro futuristic vibe of the 1992 stock imo. They make the train look more dated, not it a worn out way, but in a way that the motors don’t sound like they were built for the train and look added on. The same thing can be said for the added window frames.

I understand they are needed for practical reasons though.

As I responded the way they suit the 92 stock is in a subjective way, not practical way.

It sometimes blows peoples' minds on this forum that one can like something for reasons other than 'practicalities'.

They're reacting based on a longstanding trend of a certain sort of people seriously arguing the toss, based on nothing but guesswork & wishful thinking.

Whether or not such a reaction is justified is debatable, but it's not "blowing their minds" and it's a bit sensationalist to suggest that.

What? You can't really see the motors, and they don't have a significant (or really noticeable) effect on the aesthetics of the 1992 stock. Am I missing something? I understand where you're coming from with the window frames and the auditory experience, but not the motor's aesthetics. That's one of the 'invisible' bits of the upgrade.

It’s not about seeing the motors it’s about the vibe. And for me the come does influence how the train looks.

Video is of a ride on the "Central line Pre refresh 2011" by Youtube member Graham W.

Can somebody explain what that intermittent noise that can be heard on the 1992TS when coasting and going at low speed and stationary?

It is comparable to an irregular note that can be heard starting and restarting; it is audible at the beginning of this video.

This noise can also be heard before the train accelerates after prolonged dwell times, a sort of high-pitched noise before the DC hum.

That sort of high pitched squeal noise? Is that what you're referring to?

Can you list a few timestamps from the video? I'm not sure what sound you're referring to.

The Particular sound that I was referring to is the subtle though distinctive, noise that these trains emit from when starting from prolonged station stops, it is a sort of brief low to high note, and sometime scan be heard intermittently at low speed. CAN BE HEARD AT: 0:07

Sounds like it could be a motor or power electronics cooling fan starting.
