Raven and Gressley Pacifics were tested on same hard duty. City of Newcastle used 59 lbs coal and 40 gallon of water per mile and Flying Scotchman used 53lbs and 38 gallons.

A2/2 were best looking UK Pacific for my eyes but I think it is the bigger than usual distance between boggie and drivers. It suggests race,class whatever. Just like the Belgian class 12 Atlantic: https://en.wikipedia.org/wiki/SNCB_Type_12

A three cylinder School has a bigger swaying couple and Bulleid modified one to have no reciprocatory balance at all before doing it on all MNs. The cheap and dirty solution for the GWR County was maybe just to have had stiffer horizontal springs in the boggie .

Ravens Pacifics were (Judged by Gressley) not so good as Gressley Pacifics that was no so good as a GWR castle. Morale .Pacifics were toys. B16s had an impressive longevity. It could be fun if someone could photoshop a B16 like(that is three cylinder front wheel drive ) GWR express with coppercap compared to a B 16 and normal a Castle. A Three cylinder five feet eigth drivers Castle with all cylinder in line and front driving wheels a little further aft will be much kinder to track and more steam economic.

Lovely picture and I was mis-guided by Your Diesel avatarl

I did time on Motortorpedo boats(Old German E-boote) with three twenty cylinder Mercedes 3000 horsepower diesel engines each. I will hate Diesels to my dying day. Whereas a front drive three cylinder 4-6-0 steam locomotives is pure music. My only footplate ride was on a Heissler along Pacific coast in Tillamouk . Memory is still swimming.It was lovely.

Very nice pictures of longlived,sensible locomotives. If they had gone to Barry there could be made a lot of ultra important tests. Compound versus simple, How fast can a 5feet 8 threecylinder locomotive run etc. Material for daydreaming Thank You.

Lovely model of a very well designed prototype. It must have been one of the best UK locomotive investments . If only the comparison report B16/3-B16/2-B16/1 had been made public or put to York. Same wheeldiameter as Prussian P8 (3556 built) and less harmful to track and crew,because being three-cylindered. Are there some pictures of B16/2and 3 models on this site?

I did some cleaning on my download archive and found this. It has probably been made by me as it is rather primitive. https://i.imgur.com/QnlK5Tp.jpg I still find the possibilities of a Raven like front wheel drive Pacific interesting

Can this: http://www.rmweb.co.uk/community/uploads/monthly_09_2017/post-898-0-40142800-1505684845.jpg be made into an inside cylindered outside framed illegetime child of straying GWR City Of Truro?

The Prince of Wales 4-4-0 from LNWR had 20.5 inch inside cylinders ,that is half an inch more than Britania 4-6-2. A Britania with outside frames/inside cylinders and 7feet 6 between leading driving axle and trailing bogie axle instead of the Britania 5 feet 6 as is. Lovely and easy to maintain. Compounded like the austrian 4-6-0 it would also have been the most powerfull british pacific https://de.wikipedia.org/wiki/KkStB_9

The Belgians made class 12 Atlantic thus,so why not a Pacific. Very fast and powerfull https://www.altaplana.be/en/dictionary/12.004

A first step in the rational 1984 range of standard locomotives. All shall have 5 feet driving wheels and wide fireboxes. Hail Big Brother. https://imgur.com/GqDOFMW

A three cylinder locomotive can have shorter connecting rods and by driving first axle cylinders can be closer together. https://imgur.com/a/MeLZT

I am composing my Tombstone and it is going be this Faboluos picture of Corbs frontwheel drive 4-6-2 NE locomtive lasered on swedish diabas or dolerit with the words more or less: Thanks for having seen the ligth. Where on web can I find a higher resolution original picture? One of the women around here is graphic worker.

Thank You and I have tried Paint,but still have some difficulties https://i.imgur.com/KgVwSm2.jpg

Thank You but I used a scissor and tape. More suitable for my age. When mr Riddles got older, he dreamt of having made the Clan class as Caprotti 4-8-0 and beated the Chapelon for the run of having made worlds best locomotive. LNER could have done prewar and would have looked much better https://imgur.com/mv7Jp6V

please click on link above 4-8-0 haunts my dreams. I will try to print two pictures and cut and paste so that steps up to cap is just behind fourth coupled wheels just like the french 4-8-0 that is known manyeverywhere to have been the ultimate and most efficient steam locomotive. The Corbs/Thomson version can be even better and look much better. Boiler diameters are equal(ultimate power) but the Chapelon two throw crank is a not so nice thing. Francis Webb comes to rescue Two outside 17 inch high pressure cylinders sitting 6 feet 3inch apart will clear platform edges in al future. A single 36 inch low pressure can easily sit betwen frames and a single throw crank is better than a two ditto. The thermodynamical cylinder losses are less than the Chapelon child. Not much but still some. Mr Webb will smile ,I think,having fathered worlds best locomotive and it only makes sense in England

Italian and very good 1904 https://en.wikipedia.org/wiki/FS_Class_600

Mr Bulleid had maybe made his Atlantic more like the Belgian Class 12 http://4.bp.blogspot.com/-RaZmbs2Uf8o/T58Rtce2r4I/AAAAAAAAMoY/r8ikKCrfBs4/s1600/SNCB+12.jpg Inside cylinders by the way. https://www.altaplana.be/_media/photos/la-douce/884479_263495363787090_349091688_o.jpg?w=1024&h=682&tok=df06f7

According to mr Giesel who made locomotives for a living,two sixcoupled groups be they Garrat or Mallet are less efficient adhesion-vise than a normal ten coupled. Dare I say that an inside cylinder ten coupler with flanges on all wheels is up til now the most logical UK locomotive that was never built. And it could have run everywhere within shrinking loading gauges and used less coal.. The very nice Bulleid Southern 2-10-0 can just get inside some places today but will have to be three-cylindered I think.

Another very British 2-10-0 https://imgur.com/a/DodBL Two inside cylinder divided drive compound https://imgur.com/ZlssxtV Krauss-Helmholtz truck up front and flanges on all wheels

Best looking Pacific ever Thank You very much I have tried to repeat Your deeds on this but cannot.What program to use? https://www.Hornby.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/r/3/r3171-cock-o.jpg

The french 4-8-0 has nearly same boiler diameter and center over rail as the P2. If chimney and dome had been lowered it could run UK. Apart from cab width. The driving wheelbase is same as P2 that gave problems and I do not know what the french did. The two first wheelsets were driven and could have no lateral flexibility. And the two last had an awfull lot of hot boiler and ash close by. The undivided drive UK version can have plus minus an inch on second driving set and that is maybe enough.

Picture is stunning. I am breathless Can we see a Pacific versio also? For the the most dramatic british locomotive that never were put the cab forward like Chapelon http://thierry.stora.free.fr/pics/dwg240_1.gif https://camo.derpicdn.net/a64e809d5fe642c88b0fcaf8de7328f44d0a7d7c?url=http%3A%2F%2Fforum.e-train.fr%2Falbum_mod%2Fupload%2Fgrandes%2F46cb68ffe998fe0bd27ed3972f9f1c83.jpg
