I have just come across this thread... 

Yes, the omission of an R-T-R BR Class 4 4-6-0 has indeed created a very big gap in the range of R-T-R N-Gauge steam engines...

80 locomotives were built:-
75000 - 75009 built Swindon 05/51-10/51 (Type 2 tenders) allocated to Western Region
75010 - 75019 built Swindon 11/51-03/52 (Type 2 tenders) allocated to London Midland Region
75020 - 75029 built Swindon 11/53-05/54 (Type 2 tenders) allocated to Western Region
75030 - 75049 built Swindon 07/53-10/54 (Type 2 tenders) allocated to London Midland Region
75050 - 75064 built Swindon 11/56-07/57 (Type 2A tenders) allocated to London Midland Region
75065 - 75079 built Swindon 08/55-01/56 (Type 1B tenders) allocated to Southern Region

Nos.75080 - 75089 destined for the Eastern Region were cancelled.
 
BR Type 2 tenders had a water capacity of 3,500 gallons and carried 6 tons of coal, and water pick-ups could be fitted if needed.
BR Type 2A tenders also had a fall-plate and gangway doors were fitted.
BR Type 1B tenders had a coal capacity of 7 tons; the water capacity was 4,725 gallons and water pick-up apparatus could be fitted if required. On the Southern Region there were no water troughs, hence the need for a higher water capacity. 

During 1957, Swindon experimentally fitted No.75029 with a double blast-pipe and chimney - this modification was a success and improved their steamit was planned to modify the entire class, but this did not happen, though Swindon did modify a small number of the Western Region's allocation. However Brighton Works did modify the entire Southern Region allocation of the Class 4s, but their style of double chimney differed in appearance from the original Swindon pattern.

The Class 4 4-6-0s were primarily designed for the Western Region and intended for work similar to that done by the "Manor" Class 4-6-0s (though British Railways placed the "Manors" in the Class 5 power rating), both classes were intended for working over those lines where a heavier engine would have been prohibited because of its axle-weight, and so were given a "blue" route restriction, indicated by a 4 inch diameter light blue disc painted on the cab-sides.

I've been keeping my fingers crossed for a 21st Century N-Gauge model of this class for so long that some deformity may soon be creeping in..! 

@Ben A is it possible to add the Pullman brakes to my existing order, not sure if you have committed your order into the factory yet ?

Craig

Good to hear you've got your (sinus) rhythm back mate!

Quote from: ten0G on July 31, 2026, 09:06:44 PMWas there a K27 bar car?  Without one, for the area and era I have in mind, K27's are sadly not an option. 

The Original "Hadrian Bar" was converted in 1948 from Kitchen-Third Car 59. Info that I have suggests that was a wooden-bodied K Type so subtly different to the Revolution offering?

Its numbered 6242 (City of Glasgow) in lined-black, however its carrying 6245 City of London name plates. So I understand its not as originally passed out from Romany Works, Poole....

6242 "City of Glasgow" was the only LMS Black release in the Poole era. (Ref 1811)
The "City of London" name first appeared on a Chinese made (old tooling) BR Green model as part of the Royal Scot Trainset (Ref 370-100)
So the two were never produced concurrently (and not even in the same country) so a Factory error is extremely unlikely. Far more likely to be an after-market name change without renumbering...

Some of us have air/air heatpumps (aka reversible aircon down under) and are feeling quite smug. I think it's going to get rapidly more popular than the orrible air/water stuff

Instead of suffering the stifling heat of California in July, I am currently enjoying the stifling heat of south-west England in July.  Anyone who has the bright idea of introducing air conditioning to the UK (or ranch salad dressing) could make a fortune!

Because of my current location, I am away from my reference documents at the moment but I will check when I get home if no one else responds to answer this question in the interim.

Quote from: Papyrus on July 31, 2026, 08:42:23 PMI do agree with you there. The Duchesses are handsome looking engines, even to us Eastern types.

Definitely - although I prefer the streamlined version myself.

Here's my collection covering most of the variations - streamlined, de-streamlined and never streamlined, with single and double chimney in each case where appropriate.

Not all (or, maybe, not really) SPAM, however.
The streamliners are all from Ross Teirney's kits fitted to modern Farish chassis.
The non-streamlined ones, whilst being either properly-Poole or the Chinese modified version, have all been modified by me - those that were never streamlined have had the running plate front filled in as Farish got that bit wrong, whilst the one that is an ex-streamliner sports the flat-topped smokebox - which they all had until their next boiler replacement when they received a fully cylindrical smokebox.
Also, 6230 Duchess of Buccleuch has been given a 3D printed replacement smokebox with a single chimney.
They've also all had a respray and etched nameplates fitted.

Quote from: Bob G on July 30, 2026, 05:57:29 PMThere used to be a double chimney kit for the Peco jubilee. Also isn't there a current Farish loco with a double chimney? Farish spares are pretty good source of bits. Failing that a dead Dapol 9F?

Bob

Thanks for putting me on a possible trail. FarishNSpares do a number of spare smokeboxes with double chimney for just a couple of quid or so. Worth buying one and getting to work with a razorsaw.

And I do think it makes a really smart combination. Even to a dedicated adherent to the faith of that other big 4 company with lettering beginning with L such as myself....

Cheers,

Colin.

I do agree with you there. The Duchesses are handsome looking engines, even to us Eastern types. The lined black livery suited them particularly well, I think.

Cheers,

Chris

Chris agree with you there one beautiful loco. Try Lee farish n spares
