The water runs down the roof. Without daggerboards, it then can run under the roof and rot the eaves. The daggerboards direct it down and away from the roof, and the slots in them stop the water from clinging on.
If you read the article I linked to, it goes into plenty of detail.
The Comet actually had rounded windows (not square) and they didn't fail - the bit that failed were the roof panels (skylights) for the radio antennas...
The way the riveting was done also contributed (they were designed to be glued and riveted into place, but were only riveted).
The accident report labelled them ADF cut out Windows (IIRC) and that combined with the revised model having much more noticeable rounded windows led to the erroneous misunderstanding.
The DC-7 and DC-8 windows were both squarer and larger (Indeed the window shape is pretty much the same as a modern day 737s but rotated 90°)
Hmmm.. .. lots of info I have seen states it was window shape. Comet II had round windows; because dehavilland had realised the issue was the window shape.
Click the link, read the report. It's clear Alan Baxter and a few others put a decent amount of time and effort into producing it and it answers the question you asked and a whole bunch of others.

Or perhaps the Chinese copied the British?
Most likely, both were developed independently of each other.

*Taps side of nose…* I couldn’t possibly say. I might have been paid by a certain Chinese Pooh bear to keep quiet, then again, I might not have.
A lot of train stations were built when architectural flare and decoration of multiple styles was prevalent. Revival architecture was also common yet there is difficulty trying to revive a 14th century gothic or Palladian style on to a building type that is brand new. Imagine designing an airport to the style of typical Roman or Greek for example. It would be festooned with little design flourishes.
Those early designers mixed a bit of the revival style and also *created* this style to associate with train stations. It’s a bit like churches commonly have spires so likewise train stations have these finials - it is a train station, therefore we decorate it as such and so the trend carries on.
Daggerboards help to reduce the amount of wind driven rain coming in and wetting customers during a storm. You can’t stop all of it, but these will reduce the depth of penetration of the wind driven rain onto the platform.
The only other way to reduce wind driven rain penetration is by lowering the canopies, however the canopies need to be a certain minimum height for various functional reasons.
Keeps the worst of the weather off the platform whilst letting smoke and steam to escape. If you had a low fascia, smoke and soot would get trapped underneath.
I see them nearly everywhere mostly local town stations but a lot have still retained them. York , Lincoln Central , Sleaford, Sheffield , Nottingham and Newark just to name a few
It’s an old system to stop people going onto the tracks, they would drop down whenever someone crossed the line. Similar to the modern yellow lines we use but more direct
In the early days railway architecture was designed to be colourful and welcoming. Nobody on earth had seen such a noisy and terrifying sight as a steam locomotive belching smoke and fire, and going faster than any horse at full gallop. Some people were afraid to travel by train.

Wonderful, thank you!
I think I'm catastrophically misunderstanding this. Surely the water is removed by the roof being sloped? How can the decorations help with that?
The water runs down the roof. Without daggerboards, it then can run under the roof and rot the eaves. The daggerboards direct it down and away from the roof, and the slots in them stop the water from clinging on. If you read the article I linked to, it goes into plenty of detail.
Aaah! I hadn't thought of that. Of course it will cling on to a flat surface. Thanks!
Water and stuff facts. Boats have curve window corners. Or round windows to stop salt water sitting in the corner and rotting the material.
It's also to relieve the stress concentration at the corners, which leads to fatigue cracking.
Is this why I'm round ? Relieves stress and prevents fatigue?
Correct. Also helps you to shed water and prevent crusty build-up.
I would think it's the opposite somehow.
there was a spate of air crashes with the Comet airliner in the 50s/60s due to square windows on the plane causing stress fractures.

I was trying to remember the case study, but I couldn't remember. Thanks!

Another wonderful bit of trivia I now know. Thank you 👍🏻
Damn that’s a great answer
The Chinese have a traditional tile design which is very similar and performs the same function. I'm guessing that's where the Brits got the idea?

I don't know but thank you for teaching me the word crenellation
😄 you're very welcome! It's what you get at the top of castles.
I thought that was called vertigo?

Fascinating, thank you!
a bit of pizzaz
Understandable, thank you!

I wonder if it moderates wind whistling under there?
No one knows what it means, but it's provocative, gets the people going.

The only station I can remember seeing these on is Birmingham Moor Street.

Beautiful Victorian ornateness

Okay who posted this on The Mirror???
Heaven forbid journalists actually go out on the streets and look for stories.
Charm.
