Modern Image

To modellers used to working in OO or N the thought of modelling in a scale where there is no RTR trade support may seem insane – to model a less popular era in that scale may seem a step too far. The attraction is often summed up with the phase “the ideal size” by many people, closely followed by “if only ….”. Primarily 3mm is a kit and scratchbuilders scale. This article aims to show what is available if you want to dip your toe into the 1:101 scale world. That said one of the real attractions is that once you have decided to scratchbuild what you model is only limited by the information you can find, so everything becomes modelable.

Ready to run

First to consider has got to be some of the Tri-ang range. Luckily for the modern image modeller some of the best models Tri-ang produced were of the current prototypes of the time. Despite being produced 50 years ago they consist of some fine mouldings but raised plank lines and door edges are the order of the day. They are, however, easily removed and scribed in.

Modern ready to run does not exist for UK stock. Some assembled and painted kits are provided by 3SMR from commercially available parts.

Kits

Many kits are, or have been, available in 3mm over the years but kit production runs rarely exceeded 50 pieces and generally have been much less. 3mm modellers tend to be hoarders and often buy when products are available in the knowledge that they probably won’t be able to when they need it. As a consequence unmade kits will eventually reappear through the Society secondhand sales, so the list includes many items long since deleted from sales lists.

Maurice Pilsworth produced a range of bodies and bogie sideframes, long since out of production, using an early resin that is harder and more brittle than most modellers are now used to, but the mouldings are stable if a little sticky before painting. The windows on some kits was moulded in a clearer resin. Some additional details may also be included.

3mm Scale Model Railways market 2 ranges of kits. These are either a combination of etched brass and whitemetal or resin bodies.

Judith Edge Kits have produced 3mm kits based on their etches in larger scales.

The late Bruce Smetham produced diesel bodies in modern “milky bar” resin. Some of these are now sold by 3mm Scale Model Railways

Worsley Works has an extensive range of 3mm locos, multiple units and coaches in etched brass and aluminium.

Chassis

Luckily for the modern image modeller working in 12mm gauge a combination of cheaper production and a boom in eastern European TT interest has seen a flood of high quality chassis at very good prices.

PIKO – leaders in the field of value TT chassis.

Siemens Taurus Bo-Bo electric is available from €60 new. The chassis has 25mm wb bogies (8’4), 9.4mm wheels (3’1½) at 82.5mm centres (27’6), and provides the perfect chassis for class 24/25/73 and 40 (as a 2Bo-Bo2) with very little modification. This chassis can also be stretched to fit other 8’6 bogied locos and multiple units or split to provide two 8’6 drive units with an additional motor.

The Vossloh G1206 Bo-Bo costs about €75 new. The chassis has 20mm wb bogies (6’8), 8.3mm wheels (2’9) at 60mm centres (20’). Although underlength bogies and small wheels the chassis is narrow enough to fit a class 16 and with stretching will fit both class 15 and 20.

The 151 electric is a good match for class 37s if you can accept the offset centre axle.

TILLIG – Generally more expensive than PIKO but using high quality chassis under many of the Berliner Bahnen or modern bodies. The Tillig TRAXX Bo-Bo diesel chassis has 7’6 wb, 3’6 wheels and 37’9 centres. An etch is being developed by Andrew Shillito to extend the bogies to Co-Co giving a chassis that is a close fit to the middle 4 axles of the 47 and 56. Fully detailed examples are over £100, but ex starter set examples are often below €70 and matching wheelsets are available as spares for about €10, but Jacksons are a good visual match.

(BTTB chassis dimensions from Mixed Traffic 51)

V200 – 26mm wb bogies with 8.5mm wheels, 95mm centres

T435 – 19mm wb bogies with 8mm wheels, 52mm centres

M61 – 16+16mm wb bogies with 8.5mm wheels, 84mm centres

Shunter – 12.5+10+12.5mm wb with 8mm wheels

E49 – 27mm wb bogies with 10mm wheels, 67mm centres

E42 – 27mm wb bogies with 10mm wheels, 645mm centres

E94 – 20+18mm wb bogies with 10mm wheels, 72mm centres

MEHANO – Production of their Blue Tiger has been on and off and their 1:120 class 66 is long awaited. Expect to pay at least £130 for the Blue Tiger and you get a superb chassis for both the class 58 and 60. Additionally a change of cabs gives a close approximation to a class 70. Bogies are 15.5+15.5mm with 9mm wheels, at 122.5mm centres

Shunters

Diesel locos

For all bogies the dimensions are from the outer axle first. 

LMS 10000 – Resin body by Maurice Pilsworth

Requires 8’+7’8 wb bogies with 3’6 wheels, at 35’2 to centres of middle axle (pivot centres are 35’6).

20 – Etched brass and whitemetal kit by 3mm Society. Complete kit to make an unpowered locomotive. Whitemetal castings for the bonnet need heavily thinning down.

20 – Resin body by Bruce Smetham based on the 3mm Society kit as either headcode fitted or disc fitted versions. Disc fitted version was also sold by 3SMR

Chassis is 8’6 wb bogies with 43” wheels, at 24’ centres. Geoff Helliwell produced a narrow power bogie to suit years before the kit was available. The Piko G1206 chassis can be stretched to fit.

 

21 – preformed etched body kit by Worsley Works.

Requires 8’6 wb bogies with 3’7 wheels, at 28’6 centres.

 

22 – preformed etched body kit by Worsley Works.
22 – preformed etched body kit by 3SMR.

24 – preformed etched body kit by Worsley Works.
24 – resin body by L+J.
24 – Resin body and Piko Taurus chassis by 3SMR.

Chassis has 8’6 wb bogies with 45” wheels, at 28’ centres. The Piko Taurus chassis is close.

 

25/3 – Etched brass and whitemetal body and bodies sideframes by 3SMR.
25 – Resin body by lennyapplegreen. Replacement grilles available from Andy Shillito.

Chassis has 8’6 wb bogies with 45” wheels, at 28’ centres. The Piko Taurus chassis is close.

 

26/27 - conversion possible from the Bruce Smetham class 33.

Chassis has 10’ wb bogies with 43” wheels, at 29’ centres.

 

28 – Part preformed etched body kit with bogie sideframes by Worsley Works.

Requires one 8’6 wb bogie and one 5’11+6’2½ wb bogie, all with 3’9 wheels, at 32’4 centres (the centre of the 3 axle bogie is 1” inboard of the axle).

 

29 – preformed etched body kit by Worsley Works.
29 – Etched body kit by 3SMR.

Requires a 8’6 wb bogie, with 3’7 wheels, at 28’6 centres.

 

30/31 – One of the best models in the Tri-ang range (T96). Finely proportioned, flush glazed and separate handrails and some very neat detailing. The bogies have good detail but have a flat backing. Replacement magnets are available from the Society. The Tri-ang power bogie is easily adaped to run through Peco HOm points by easing the back-to-back of the wheel sets.  If using the Society etched chassis whitemetal replacement sideframes can be fitted. Adding a second power bogie or re-wheeling the trailing bogie has the advantage of extra pick-ups. The Tri-ang model is of the original Brush/Mirlees locomotives. Conversion to a more common headcode boxed cab-roof or the rebuilt English Electric engined exhaust arrangement is a plasticard job.

Bogies are 7’+7’ wb at 28’10 centres. The centre axle has 39½” wheels, the others 43”. The Tri-ang chassis is to scale except for the dummy centre wheels.

Requires 9'2 wb bogies with 44” wheels, at 38’1 centres.

 

70 – The Mehano Blue Tiger is possible conversion. Needs 26mm extra length, 5mm height and 3mm width. Replacement cabs will do some of that - more thought (and a drawing) needed!

 

15/16/68 – nothing available yet.

Electric locos

70, 73, 74 and NER ES1 as etched kits

Coaches

Tri-ang SR luggage van -  the length and width can be corrected but a much better model can be made from 2 Parkside PMVs for the same amount of work.

Kirk LMS 50ft full brake – plastic

Mk1 – Kitmaster produced BSK, SK, RFO and CK as plastic kits,  readily available secondhand as either built or unbuilt examples. MTK,  Worsley, 3SMR and Bedford also cover almost all Mk1s as etches. The Tri-ang Mk1 style coaches are all 57ft and best used as donor bodies for other conversions.

Mk11 – 16 PV and AC types are covered by Worsley.

MK111 – Worsley produce 4 types to run with their 125 power cars.

Multiple Units

T190/136/137 Class 104 – Another very nice Tri-ang moulding. The power is from a very clever split chassis bogie. The glazing is not flush and difficult to correct and the bogies have Tri-angs standard size wheels that are oversize. They do need replacing to work well with Peco track standards so pinpoints and pick ups can be added at the same time. There is no interior.

Worsley again list a vast range of 1st generation EMUs and DMUs and a few 2nd generation DMUs. As with coaching stock the world ends in the 1990s.

There is even a good diecast 1992 tube stock from Realtoy (on a 16.5mm chassis!)

Wagons

RTR – Tri-ang produced some that are still worthy of consideration for the body mouldings only, in all cases the chassis are typical 1950’s mazak lumps that are best replaced.

T70 16T mineral – although inaccurate in its day BR did later built some 17’6 versions (MTV) that only require removal of the top flap.

T171 Bulk Grain  - the body is dimensionally accurate and can be upgraded and fitted to either a cast whitemetal chassis or the exquisite Andrew Thomas/3mm Society etched chassis.

T172 Low sided wagon – A rather coarse model, but dimensionally correct.

T174 Bogie Bolster C – Another slightly coarse model, but dimensionally correct.

T272 Bogie Caustic tank  - one of the best wagons. Requires new bogies. Can also be re-worked into the chlorine tank.

T276 Conflat L – the containers are a good basis for detailing but the body is rather basic.

T278 Presflo - the body is dimensionally accurate and can be upgraded and fitted to either a cast whitemetal chassis or an Andrew Thomas/3mm etched chassis.

A few RTR continental wagons are close or easily modified for 3mm use with correct wheel sizes and buffer spacing. The Roco van becomes a VGA and Tillig produce a sliding door bogie van.

Thanks to the 3mm Society and commercially a wide range of wagon kits are available.

Buildings

The trend for resin buildings has benefited 3mm scale since many of the large buildings are modelled under scale to keep the price reasonable or to fit the standard boxes. Many HO European and American kits are also small enough to use in 3mm.
