.....get it even a bit right ?

Hundreds of thousands of pounds spent producing Downton Abbey for our Christmas delectation !

Now, I don't care if the spoons on the dinner table were made in 1927 but where on Earth, in 1924 would the local railway company.....LNER by then....have managed to rustle up a mid-1950s British Railways Standard Class 5 locomotive for the family's shooting trip ?

Surely the railways are the one industry where every aspect of history is well known by thousands of people. A phone call would have put the producers on the right track ( pun intended )

I won't even mention the Routemaster bus in Foyles War a couple of months ago !

Blast...I've gone and mentioned it !

Some sort of Pullman coaches by the looks of it, certainly not Mk 1s. I suspect they just had to use whatever the preserved line they use for station scenes happened to have.

If Nicole has taped it I will check it out and find out what stock was used. I know they use the BlueBell railway a lot, might be their ex golden arrow pullman stock. Don't think they have had a black 5 down there for a while tho.

I meant of course a BR standard Class 5 MT, which i think Ted was referring to. The Bluebell Railway has one, but its boiler is 350miles away from the rest of it.

Heh!

Wasn't really watching it (corner of the eye, thing!), but about 5 seconds after the scene cut away, I said to SWMBO, "I'm sure that was a Routemaster and not an RT".

;-)
       
 Why can't they...... - Slidingpillar
Not many RTs are pre-war either. Quick dating test of photographs between pre and post war is has an RT got a roof number box. They were deleted on post war production.

Yes I know that is exactly what a severe bus anorak would say, but hey, my first word was bus, not mama or papa.
       
 Why can't they...... - Ted

The coaches weren't Pullmans ( Pullmen ? ) They looked pre WW1 stock varnished wood and shorter than normal 60' stock. Had a box van on the back.


The bit with the train passing through the valley was the NYMR, I'm sure. The loco may have been 75029 The Green Knight it had some awful totem on the side of the tender.
       
 Why can't they...... - Zero
Departure was filmed at Horsted Keynes with the Bluebell Metropolitan "Teak" Stock, It was then filmed at the NYMR, it was their "LNER TEAK" stock.

The line was right, the station was wrong, stock was right, and the loco was BR Standard Class 4MT 4-6-0 locomotive No. 75029 built at Swindon Works in 1954
       
 Why can't they...... - Ted

I thought the first train was the Metropolitan set. I think it was in the Railway Magazine earlier in the year being dragged around by the Metropolitan tank engine. Along with the station, wrong for a series based in Yorkshire. But then, so is Highclere !

I'm not sure the LNER stock was right either. Remember, this is the Summer of 1924, 18 months after the grouping and any new LNER stock would have been on the ECML. A train as depicted would probably have been NER stock or possibly, if in the Border country, NBR coaches.

I'll mention it to dear Julian at Maurice Bowra's next bridge evening at Sezincote. I'm sure he won't give a stuff !

 Reading viaduct - Focusless
As you may know they've been building a viaduct near Reading station for the last year or 2, and I've been watching the work progress on my commute between Reading and Bath.

Well this morning as the train left Reading I looked out of the window to see how it was getting on - it had disappeared! Then I noticed we seemed to be higher up than usual. Yep, the train was on the viaduct.

 The Blimp - Mike Hannon
We were out walking the other day, in countryside a few kms north west of Limoges airport. Suddenly there was a huge roar and this (not the one in the picture) appeared at what seemed to be almost tree-top level. It was obviously doing a very slow circuit from the south onto the normal north approach to the airport. I thought last night's wine had come back to haunt me.
Apparently, underneath, it's an Airbus 300. I read that there are only 5 but development work on a newer version is under way and local TV news said they were using Limoges airport for some sort of short landing testing.

I see them occasionally coming into land at Broughton when I happen to be passing n the A55...big things !
       
 The Blimp - Bromptonaut
It's formally known as the Beluga and is used to carry Airbus components from factories around Europe to the assembly lines at Toulouse and Finkenwerder (Hamburg). We have friends in the Wrexham area and like RP see them from time to time in and out of Hawarden. Told they're particularly impressive seen from Hope Mountain, an area of high ground overlooking Hawarden, but never managed to be there at right time.

It's predecessor the Aero Spacelines Guppy, based on a Boeing Stratocruiser, was even more impressive:

There is a preserved example up the road at Bruntingthorpe with another at Toulouse. NASA still have on operational in the States.

As a satisfied 125 commuter (3 days a week) I hope the Hitachi is as good as they suggest; should find out in 2017.

In the next few months the early prototype will be tested on the rail network.

Perhaps our resident trainspotter could post some footage?

Arrived at Southampton docks this morning, will be transported by road to the Old Dalby Test Track (Between Nottingham and Melton Mowbray) by road for testing. Don't have access to the running schedules on the DTT and access is limited, but I am due to do some dog training at Tollerton (near the north end of the track) so may try and get some shots. Either way I shall be trackside for the first mainline tests.


A word here about the train its replacing, the British Railways Class 43, known by all as the IC125. These have been pounding up and down the GWR and the ECML at a solid 125mph since 1973. (apart from the two sets written off - The Southall and the Upton Nervet crashes). All have now had the Paxman Valenta (known as screaming valentas) engines replaced by MTU, but essentially still the same train. Its is, in my mind, without a shadow of doubt, the finest trains ever built anywhere in the world at any time and they saved British Railways and acted as the springboard for revitalised rail transport.

Last flying season for the Vulcan, only a few airshows left. Last one is at Dunsfold in Surrey 29/30 August. Even if you're not really into a/c it's worth seeing. Saw it last year on an impromptu 'airfield beat up' at (very) low level, very good. It looked impressive last year, lord knows what people thought in the 50s when it first flew.

Well i suppose i did ask! I look at it and think it's still looks quite modern even now. Back then when it first flew not that long after the war, i always thought it must have been incredible looking. Making bombers just a few years before look very old fashioned.

It was designed to get to Moscow at just under mach 1 at a height of about 55,000 feet. Like to see an AA gunner hit that.

When you think about it, despite being a magnificent looking* and sounding aircraft, it wasn't actually that good. Couldn't fly above Mach 1, crashed and wrecked with alarming regularity, unreliable in service, and when actually called upon to drop real bombs on real targets, mostly missed.


* The best looking of the "V" bombers was the Victor. What a spiteful, malevolent, aggressive, dangerous looking beast that is.

IIRC only the pilots had ejector seats. The rest of the crew would have to bail out through a hatch in same fashion as on Lancaster etc.

At least one crew successfully evacuated under those conditions when XM610 crashed after an engine fire over County Durham.

I think one idea was to have a cockpit that jettisoned everyone to safety. However it was compromised by having to have two pilots. The layout of the cockpit then didn't allow for it. It was a very cramped layout.

Well if they are flying out to drop "the" bomb, they ain't flying back to anything left now are they.
       
 Back to aircraft - sooty123
Most aircraft of that era suffered from the same problems. Crash rates were high for that era dozens of military aircraft lost per year were nothing remarkable in that era. More a reflection of the era than the aircraft per se. Iron bombs were similar a problem you needed lots to make a dent in something, they got (just) enough to damage the runway.
Unreliability is an interesting one, ironically the least safe of the three v bombers was the Valiant but was also the most reliable. Maintainability being thought about from the very beginning.

It was shots of multiple rehearsals from a chase plane, helicopter at one point. it was never in the way or flightpath.


Good job they didn't use a small drone, it would have got sucked through the air intakes!
       
 Wow! Dreaming? - WillDeBeest
'Near-vertical' is a bit strong! An empty (no fuel) 787-9 weighs 138,000kg, while its engines are rated at 320kN each. So that's enough to oppose gravity on rather less than half the mass of the plane, never mind accelerate it upwards.

Z will understand that the head-on shot at takeoff is taken with a very long lens, so there's extreme foreshortening of the fuselage. When the tail drops away, that exaggerates the apparent angle, making the climb appear much steeper than it is.

There's a less giddy account here, with some insight from my favourite debunker of aviation nonsense, Patrick Smith.

I suspect it would still look pretty impressive from a crowd line parallel to the runway and is a demonstration of the machine's capability and handling.

While the power/empty weight statement is true a show like that doesn't need acceleration, indeed the pilot is probably trading speed for angle of climb.

I've seen a DHL 757 do some similar manoeuvres when displaying at Duxford a few years ago.

Obvs there is acceleration from brakes off to rotation. I'm suggesting that the a/c does not need to continue accelerating during the climb and that speed may be traded for angle to give more 'wow' for the watchers.

EDIT: I replaced the word climb with show (too avoid repeat use) and inadvertently changed meaninig .

You're missing the point, Bromp. Even maintaining altitude requires acceleration, if only to oppose the downward acceleration due to gravity. Ask Wyle E. Coyote.

No, it doesn't.

I think you may be confusing acceleration with power, force or thrust. An airplane can fly at a constant speed with no acceleration involved.

I wonder how much the wingtips deflect.
       
 Wow! Dreaming? - WillDeBeest
Yes, all right. But Newton tells us F=ma. m here is constant (if we forget the diminishing fuel load) so at the very least the upward and downward Fs must be equal and opposite to achieve level flight or a steady climb (a=0). But to have got off the ground at all, there must have been some net upward a.

My real point is that 'near vertical' is nonsense, because the engines can't deliver even half the force required for a vertical hover (a=0), never mind any upward acceleration (a>0).

Oh Mr. De Beest,

You're not getting off that lightly...

Bromp: "does not need to continue accelerating during the climb "
WDB: "You're missing the point, Bromp. Even maintaining altitude requires acceleration"

>>My real point is that 'near vertical' is nonsense

Of course it is, but so is "maintaining altitude requires acceleration"

Now, stop slapping your own forehead and admit it....

You got it wro-ng, nah, nah, nah-nah, nah.

After that I begin to wonder whether Vx Astras are in fact good cars after all.

Yes, I should have expressed it in terms of force first, rather than acceleration. And I'm happy to accept that an Astra would be a good car with which to demonstrate the acceleration due to gravity.

>>Ask Wyle E. Coyote.

Maintaining altitude requires airflow around the wings sufficient for lift to overcome gravity. That will be achieved at a stable speed/Mach No and with power at cruise setting.

Mr Coyote's problem was lack of either aerofoil or forward motion.

Of course, but back to the article. In a 'near-vertical' climb, the wings contribute nothing because the force they produce is mostly parallel to the ground. It would require the engines alone to lift the plane - as a Harrier's can - which the data on thrust and mass show isn't even close to possible.

It would be interesting to know what the climb angle actually is. And for that matter the airspeed and rate of climb during the manoeuvre.

I'd hazard a guess at around 30%. Where's that pilot-y bloke when we need him, he'll have a pretty good idea.

Perhaps not applicable here, but don't forget that an aeroplane can exchange speed for height. A common aerobatic stunt.

Which is more or less the point I was trying to make.
