The Great Barnes, Clayton and Lowke Connundrum

It may sound like a firm of solicitors caught up in a Sherlock Holmes tale, but the purpose of these scribblings is to give an idea of the dilemma I'm currently having as to what outline my embryonic 'Atlantic' will take in the future.  Given that I will probably only have one shot at building an Atlantic (donor chassis are not easy to come by at my near-Yorkshire kind of price), I want to ensure that the final choice is one that I'm happy with.

So what are the options?  Ruling out the earlier Bassett-Lowke class 10 and 20 'Little Giants' on size (I've already blown the class 30 drawings up to 7.5mm scale), there are three key options to consider in outline:

1) Bassett-Lowke Class 30 outline, - 'Synolda' or 'Count Louis'...

'Synolda' on a visit to the Kirklees Light Railway
'Count Louis' at the Evesham Vale Light Railway
The classic Greenly design of these locos is a big plus point for me, however there are many differences between the survivors (and indeed the lost machine 'Sans Pariel' had a flatter cab roof), note the different drop in the rear footplate for example, whilst 'Count Louis' retains it's later cab, possibly built by Trevor Guest.  The greatest temptation is perhaps 'Count Louis' with the larger Fairbourne tender, not one for the purist but at least a Kato bogie chassis can be secreted away in there.

2) Clayton/Cannon Iron Foundries/Hunt outline - 'Sutton Belle' or 'Sutton Flyer'...

'Belle' and 'Flyer' with authentic stock at Cleethorpes
The two Atlantics that I am most familiar with, 'Belle' is very much an "improved class 30", constructed by Douglas Clayton (and indeed originally named after him) from Bassett-Lowke castings, whilst 'Flyer' is a later, further refined design completed by Hunt's for the Sutton Miniature Railway.  They may superficially look the same, but as with the surviving class 30s, there are many differences.  Tender drive would be a Kato 4w unit disguised as a 6w tender.  My biggest problem here is which one to choose - and how to explain to people that I won't necessarily be building the other one!

3) Barnes 'Albion' outline - 'Joan', 'John' etc

'John' at the Evesham Vale Light Railway
I'll be honest, in the past I've always looked on the Greenly designed, Albert Barnes built Atlantics as inferior to the class 30s.  I am of course wrong, perhaps my view was tainted by the pictures of the Rhyl line in the 80s in a rather run down state.  However, as the picture above shows, they can scrub up rather well, also evidenced by the recent restoration of 'Michael' at Rhyl.  I'd need to drop the ex-V2 Cartazzi truck at the rear and find a suitable wheelset, but these rugged machines have an advantage over the others in that the driving wheels are spaced slight further apart.  Tender drive would be as above, the disadvantage here is a slightly more open tender frame, less easy to hide that Kato unit!

4) The outsider - the 'freelance' approach...

It isn't inconceivable that a miniature railway operator could have built a loco themselves, perhaps like Douglas Clayton they bought the castings and drawings from Bassett-Lowke and slowly built it over a period of time?  We have no idea how many other sets of 15" Atlantic castings Bassett-Lowke sold that were never built, there may have been many, or simply none.  Or perhaps a complete new build?

An Oceanic Odyssey

Gather a small bunch of O9 modellers together and at some point the conversation will turn to the fact that what they would really like, really, really like, is a model of a 15" gauge Atlantic.

It can be done, Tim Ellis as has demonstrated on the  NGRM Online Forum with his model of 'Count Louis', based upon a Minitrix chassis.  Seeing Tim's model made me even more determined to have a go at this myself and a little asking in the right places produced a Minitrix 'Britannia' chassis in a state of flux, it had been subjected to a half-started attempt to build a Barlow stream-outline loco by Andrew Blackwell (who went on to use a different chassis for his project).

After a thorough examination of the parts to hand, I set to work, reducing the chassis from a Pacific to Atlantic be removing the front  driving axle position, but retaining some metalwork above to hold various new parts such as the cylinders.  A new front bogie came from an N-Brass kit fitted with Parkside wheelsets and various other modifications were made such as reducing the length of the con rods by 3mm.  After an attempt to use some old crossheads from the spares box I eventually made new ones from Nickel Silver scrap and brass rod, these slide in N-Brass GCR 'ROD' slide bars, sitting in temporary cylinders for the time being.


The rear truck is a Farish 'V2' spare that Andrew had fitted as part of his Barlow build, it certainly looks the part here.  There is one slight problem with the chassis as built, and that is my fault due to my scratchbuilt crossheads... it is a little too wide.


Although the whole thing it too big anyway (think of it as a 7.5 mm scale loco), the extra width could cause a few issues as and when a body is built, although I may be able to loose some of the excess in due course with some cunning new cylinder covers.  As to what the cylinders look like will depend on what the final outline is, there is an equal chance of Basset-Lowke Class 30, 'Sutton' outline or a slimmer chance of a Barnes style loco from Rhyl (with a new rear axle of course).

Watch this space....
