Carrying on from my fictional Romney Atlantic i now have a new one almost finished this is loosely based on a loco that was being planned for the RHDR it is a beast of a loco being a duplex drive 4-4-4-4 using the same basic dimensions of cylinders and wheels as a Romney Pacific


sorry its in 2 parts as i only have an A4 scanner and couldnt work out how to join them together


Has anyone else got any interesting ideas for locos?

In the words of the Sea Captain on The Simpsons: "yarr...give me five minutes..." ;)

Seriously though, that is a very impressive drawing. Well done indeed!

Just a thought how about a 4-8-4 using the same dimension wheels as the Romney locos but with cylinders the same as Black Prince's. Also how about an Australian outline something similar to R761 a 4-6-4 on if i remember rightly New South Wales' 5' 3" gauge network see link below. As i say its just a thought.


Cheers,
Michael

15" gauge scot :)

although not interesting - would be nice :D

Your train is cancelled due to the lack of the tea can on the footplate.

There is already one of those Callum ;)

Because banksy didnt know how and i wanted to see what it looked like, i took the liberty of mashing his pictures together to create a general arrangment type drawing of said, intended loco, its a bit of a monster ;)

Looks very similar to the bottom loco on a drawing on the mess room wall in the new shed at Romney?

Before anybody ask questions, I know nothing, other than where the drawing is pinned up

Forgive me for being dumb but is the 4-8-4 in the top of the picture the reason they extended Hythe turntable from 30' to 40'. I seem to remember reading somewhere that Greenly had designed a 4-8-4 but if it was built the turntable would need to be bigger, the turntable being extended but the 4-8-4 sadlt not materialising. If anyone knows what actually happened i will quite happily stand corrected.

Cheers,
Michael

After zooming in on the photo, the drawing is dated as 20-11-95

so unless i've read the date wrong, I wouldn't have thought so

Not really an idea as such, but the loco i would love to see is one designed by a consortium of 15" gauge railways engineers.

A loco that would include all the advances and lessons learned over the years, which would include things like the mods done to the KLR locos, cylinder designs like those fitted to the BVR locos, the ability to withstand the test of time in the same way that the Romney loco's have etc...

I know you could argue that traffic requirements are different depending on the railway, but a jack of all trades type loco would be very interesting!..

Apologies to Ben, I removed a post from here without explaining myself. Basically I removed it as it was yet another crack by a CCLR volunteer about the fact the Cub is still not in service.

I apologise.

This discussion about locomotives in very interesting, but the key issue is can any of the proposed monsters be justified?

We know that a BVR ZB class with new cylinders can haul at least 22 coaches from Wroxham, uphill, to Aylsham at maximum line speed of up to 20mph and within the existing BVR timetable. In practical terms, a train of more than 12 coaches is not required on the BVR, and probably not on most other 15” gauge lines, for no other reasons than the length of available passing loops and platform lengths.

Long wheelbases are not kind to the track. If articulated wheelbases are involved they tend to be more expensive in loco. costs. (Note to KLR readers – not always?)

From an operator’s point of view, what is required is an efficient loco that can haul all specified loads at the required speeds, needs minimum maintenance and is kind on the track. The BVR still needs to (a) make all of their ZB class “kinder on the track” by changing their counterbalancing and (b) improve some of their locos’ efficiency. However, perhaps the RH&DR has already got locos that meet their operator’s specification and do need to build any of the proposed locos quoted above.

The only real chance of getting any of the above locos built in the short term, is if somebody comes along with £250,000 plus and wants to pay for a new build that is something different.

Well said to both Dave and John. The ideal fictional loco for me is one that is efficient, kind to track, low maintenance, easy to operate and comfortable to drive AND fire at the same time. Something along the lines of the romney loco's, but with provision for wet weather and warm weather ( along the lines of a coupe/cabrolet!) standardised roller bearings all round, minimal oilling points ( volunteers always forget one ;) ) wide fire door with room to move on the footplate. All the GPS that ian's been developing, but with the boiler designed with this in mind and a cup holder in the cab.
Thing is though, I feel that to get all this, you'd come out with a rather Emmett looking affair :)

Anyway Banksy... Good luck trying to get all the above fitted into a sexy package, just go easy on the continental smoke deflector/streamlining for my taste!

No necessarily David. It depends upon whether or not you are trying to base your loco on a prototype or not. Even then, you could argue that it is based upon a design that was never built!

The Romney (RH&DR) locos are based on standard gauge stock. The Ratty (R&ER) are based upon both standard gauge and narrow gauge. Most of the Bure Valley locos are based on half size, large, narrow gauge stock (loosely!). – The original ZB’s were 2’-6” gauge Indian locos.

If the BVR was to build another steam loco., it would probably be based upon a South African narrow gauge loco., or 4-6-2 light weight tender engine based around “Wroxham Broad” as originally designed. (Except “she” was originally going to be a 2-6-2 tender loco., as a big brother to “Siân” & “Katie”, but the person who ordered her died before she was finished.)

In the “real” world, the next BVR loco. is more likely to be an upgraded (engine-wise), single cab version of the Ratty’s “Douglas Ferreira”, for all of the operational reasons that diesel locos are best! (Including “Air-Con” on hot days!) Some of the younger visitors even ask to go on a train pulled by a diesel.

Best wishes,
David Barnes

Quite by chance, I today found this passage in Peter Van Zeller's "Miniature & Minimum" column in the July 1991 issue of Steam Railway, commenting on the BVR's 1990 gala featuring Black Prince, Männertreu, Northern Rock, Samson and Winston Churchill:

Quote:
 
Behind the jollification, the Bure Valley gained firm information about the performance of different locos over their line before committing time and expense to the design and construction of their own locos. An outline plan was on view of a massive 4-8-2 proposal by TMA engineering...and Bob Meanley...This was 28 feet over buffers in the style of the South African Railways loco that appears on the company's logo...Its 7.5" x 10" cylinders, 22" driving wheels, five square feet grate and 180psi boilder promised to deliver a massive 3,912lbs of tractive effort. This would be considerably more than the 2,500lbs of Northern Rock, which was hauling fully-loaded 10-coach trains without effort in the hands of its regualr driver Trevor Stockton.


Certainly sounds impressive...does anyone know where that drawing is? Or even have a copy of that logo?
