Recommended Posts

Now that our Irish Metrovick is delivered, the Deltic is very nearly finished production, the 92 is underway and with both the 37 and Manor now making great strides, it's time to unveil our next locomotive project!

Introducing what may be our most extensive tooling suite yet, the Brush Type 2/Class 30 and 31.

Developed from detailed surveys of numerous examples of the real thing, as well as a 3D scan and an extensive range of works drawings, this model aims to be the definitive representation model of the classic BR mixed traffic design and covers almost every detail variant that existed throughout their 65-year life. This model is now fully tooled up with several working samples now in our possession for evaluation and testing.

Prototype History

Ordered as a result of the British Transport Commission’s modernisation plan of 1955, the first locomotive – numbered D5500 – was outshopped from Brush Traction’s Kestrel Works, Loughborough, in September 1957. Only the second of the ‘pilot scheme’ designs to be revealed after English Electric’s D8000 Type 1s, the initial 20 members of the class – quickly nicknamed ‘Toffee Apples’ due to the shape of their power handle – were provided with a Mirrlees JVS12T engine. The discovery of metal fatigue issues with this power unit in the early 1960s led to the decision to re-engine the entire fleet, BR choosing the familiar EE 12SVT instead – almost identical to that used in the Class 37 – albeit downrated to 1,450hp.

Acc-31128-image-GB-1200px_600x600.jpg?v=

Their place among the earliest of mainstream diesel designs plus the addition of a Spanner Mk.1 steam generator for train heating came at a cost. Tipping the scales at 107 tons required the rare use of the A1A-A1A wheel arrangement with two powered axles and a non-powered centre axle to spread the load. Despite their low power to weight ratio, even before the final example was delivered in December 1958, further orders eventually totalling 243 locomotives were committed for ‘production’ versions. These commenced delivery in February 1959 – most now with cab roof-mounted headcode boxes replacing the disc style of train identification – with the final example, D5862, being handed over to British Railways in October 1962.

31_Chinnor_600x600.jpg?v=1645294190

The early 1970s saw 24 locomotives upgraded with 320kW Brush BL100-30 alternators (the same as the Class 45/1s and Class 47s) primarily for ECS duties on the new air-con fleet out of London terminals. They were given the new TOPS sub class 31/4, numbers 31401-31424, while the remainder of the fleet was split under the 1973 TOPS scheme as 31001-31019 (Class 31/0) and 31101-31327 (Class 31/1). Class 30 was reserved for existing Mirrlees engined locomotives, although all were re-engined before TOPS renumbering. A further 44 Class 31/4s were modified between 1983-5, becoming 31425-31468 – the first ‘refurbished’ locos, with two further examples, 31400 and 31469 following in 1987/8 following collision write offs.

The entire fleet was initially allocated to the Eastern Region from new with North Eastern depots later gaining allocations. By the early 1970s increasing numbers were joining the Western Region to replace the hydraulics and by 1988 they had joined the London Midland in sizeable numbers to replace the Class 25s. Although never allocated to the other two regions they were commonly seen on the Southern on inter regional passenger and cross London freight services.

31_Chinnor_2_600x600.jpg?v=1645294276

By the early 1990s the Class 31s were starting to see increasing numbers of withdrawals, but two other sub classes were notable for their appearance that decade. Class 31/5 were former ETH-fitted machines with deactivated train heating equipment for use by the departmental sub sector – basically Class 31/4s renumbered by changing the third digit to a ‘5’, while the spot hire and open access operator Fragonset converted a pair of locomotives to Class 31/6 in 1999 with through ETH cabling and controls. These were employed in top and tail formation with a Class 31/4.

After EWS retired the final examples in 2001 the class continued to see regular test train use throughout the decade courtesy of Network Rail, which operated four locomotives, and a handful of other operators. The final NR machines were finally taken out of service in 2017, leaving just a single main line-registered example still working today – Nemesis Rail’s 31128 – although this number is expected to increase. This leaves around 30 preserved Class 31s extant with a handful of stored locomotives with various owners.

Our Model

31_3_resize_600x600.jpg?v=1645293632

Our modular tooling can be adapted to represent nearly all variations of this long-lived class from their as-built appearance right through to the present day. For the discerningly detail minded, this includes three different styles of exhaust port (Mirrlees ‘pilot scheme’ or production and EE), with or without roof fan grille, original/plated boiler port and water filler, additional roof panel for the 17 locos modified in their early days with uprated 1,600hp engines, different NRN roof antenna for both main cab roof styles, as-built ‘Toffee Apple', production and refurbished bodysides, with water filler steps, plated steps and reskinned steps and standard or vertical ‘one piece’ radiator grilles.

31_detail_E_600x600.jpg?v=1645462731

The 61 locomotives provided with trip cock gear for working on London Underground routes are also covered, while the Whitaker-style tablet catchers for use on High Dyke iron ore branch in Lincolnshire have also been moulded. The cab fronts feature a myriad of different options with disc and headcode box versions, different nose door and handrail configurations, ‘offset’ and centrally mounted sealed beam headlights, LED-style tail lights, toughened driver’s cab windows and two different ETH jumper locations. The underframe and bogies are highly detailed with numerous separately-applied parts, while the battery boxes also come in original and modified condition, the latter including the extra latches to reduce the likelihood of the doors opening while running.

31_detail_C_600x600.jpg?v=1645462800

There are numerous different bufferbeam options allowing the original ‘red circle’ electro-magnetic engine control equipment of the ‘Toffee Apples’ as well as the more standard ‘blue star’ electro-pneumatic gear of the production batch. Vacuum-braking, air braking, control pipes, steam heat and different ETH options are also appropriate to the individual running numbers, as are a full set of miniature snowploughs and a high fidelity one-piece moulding suitable for use with NEM couplers. We also have some surprise options in store that will be revealed in due course.

31_1_resize_600x600.jpg?v=1645293677

The specification continues our ambition to lead the hobby. As well as our standard and well regarded traction, light and sound package, our Class 31 introduces working radiator fans – driven from a separate motor – and separately switched tail lights, allowing not just the either end to be illuminated as required, but also individual tail lights or both depending on era.

Utilising our standard specification of ESU PowerBank capacitors for smooth uninterrupted running, ESU Loksound 5 decoder with bespoke DCC sound package by Jamie Goodman with twin speaker set up, including ‘AccuraThrash’ bass reflex speaker it promises to catch the characterful thrash of the real locomotives. It will also include a wheel flange sensor, automatically playing flange squeal on sound fitted locomotives as they hit curved track for extra realism on factory fitted DCC sound models.

Initial engineering prototype samples arrived with our production teams in mid-January, with models and their component parts assessed for fit, finesse, and finish.

31_detail_D_600x600.jpg?v=1645462928

Improvements have been identified in areas such as the roof fan grille and other areas, but overall the models are shaping up as accurate representations of the venerable Brush Type 2s, capturing their characterful quirks such as bodyside curve, plethora of grilles and distinctive cab shape.

Sad eyes here, Mind you I can always glue pick up shoes to the bogies. :)  Going from strength to strength lasts. Some output you have.

I have a big H one purchased 2nd hand on the verge of self Destruction (Myself and the owner were not aware of the Mazak Problem), New chassis runs nice and I like the Loco so I think the H one one will be put aside for now, Maybe sold off for a dew bob and a Green one (even though it is an Eastern one) may very well be bought.

Looking forward to hearing the sound.

 

 

 

Also how many functions are we looking at here, the Poor ol Dynamis is maxed at 20 Functions.

Jeez, one of the BR Diesels I like, the Class 31. Good job a pay rise was approved, lol. Just wondering if it is "Set in stone" the amount that are going to be produced for each variant? I was starting to keep an eye out for a Hornby Class 31 but with this announcement, that has put the brakes on that one.

I Have a lovely Green Re Chastised Hornby one for sale :)

That’s certainly the plan. 

You mean on your must-be-soon-to-be-announced Mk4 DVT's?

For an idiot, "sound-fitted" means loco and decoder sold as a bundle? Or a hard-wired decoder?

And non-sound can or can't be upgraded with a sound decoder?

Sound fitted means all the speakers and chip installed ready to go. Dcc ready usually means no chip but a socket for one and in some cases without a speaker.

Have to say these look great. I'm fond of BR blue and one of these would look good next to the Deltic.

George you should think about investing in a Lokprogrammer. You can remap the functions to whatever function keys you want. I find I never really use more than 10-12 functions regularly.

LOL at myself, I cant remember half of em anyway, Select uncoupling and the guards whistle sounds, etc. I usually do lights and horns, maybe flange but otherwise the rest I could not be bothered with.

Would like to move the headlights on the A to function 2 r such but nice idea that!

Beginning to get really jealous of our British counterparts - lots of shiney new stuff for them and nothing for us!

Other than new tooled magnesite wagons and mark 2 coaches and blue Tara’s and all the in stock items on irm and many announcements to come this year :)

 

the challenge with IRM is that it’s about 10% of the size of the UK market so the UK side simply supports more stuff at a quicker pace

Personally I am actually quite happy with the frequency of releases from IRM. It gives the old wallet a chance to recover. I suppose this is related to how much of each release you're going to buy. If, like me, you will take at least one of everything in your era of interest (or more as many do), then a release means at least several hundred € if not into the thousands and a breather between releases is probably required if your life isn't to be cut short in your sleep by the one laying next to you 😉

I fear that if IRM released too often, people would be forced into choosing between items they want. You can see these sorts of comments about UK outline releases on RMWeb.

And the buses!

Can never have enough buses!

To be honest, the only locomotive I really wanted is the A class and I couldn't have asked for much more so I'm quite satisfied. Just waiting on a few suitable passenger coaches to haul but my main dilemma is whether or not I should buy some of the Crossleys. If I were to dip my toe back into British Rail stock the Class 31 would certainly be top of my list.

Not to cause a frenzy/panic but if you dont grab them now and you want them later on you may end up paying significant premiums....

Yeah, feel a tad under pressure. Leaning towards the A55 but the silver looks good also.

It's been said before, and I can say that I wholeheartedly agree, the silver and the green don't show up too well in photos but they are just stunning to the eye. The green is gorgeous, and the detail on the silver really pops.

Plus, the sold-out models already change hands for over €250 on eBay, so you'll definitely be paying a premium if you want them further down the line.

If it helps with planning we have a small announcement in the next few weeks,, then something in April, something powered in late April/ Early May, something else in June, something else in July, and August and September and October (also powered) :)

So pretty much one per month from February through to October, and two of them are home-wreckers? Got it.

That's certainly good to hear. Went to Mark's and got me two A55s and really delighted with them and now, back to yourselves for the A30. Have to say that I'm really impressed with the Crossley versions - seem to have a bit more character. Anyway, this thread is about the Accurascale BR 31 so my next mention of the As will be in the usual venue.

Wow - not a pay packet will remain intact all year! Great news, though..........!

At one stage I was tempted by the Hornby class 31 so can't rule out buying some of these guys. I have a single loop track [Fleischmann radius 2] so locomotives no longer than the class 31 look graceful going around the curves. Certainly looking forward to what's in store for the Irish railway modeller.
