Review: Minerva 57XX Pannier Tank

Written by Richard Grigg, Photos by Gwion Rhys Davies


Ask anyone to name you classes of steam locomotives from the Great Western Railway and at some point the 57XX Pannier tanks will emerge, as they are, in my opinion, one of the most iconic designs to come out of the UK's railways.

A grand total of 863 members of the class were built between 1929 and 1950 across 7 manufacturers, initially for the purpose of shunting and hauling light goods trains. They soon however were seen pulling passenger trains on branch lines, suburban routes and even short main line runs.

Withdrawal of the class took place between 1956 and 1966 with 16 of them escaping the cutter's torch into preservation.

In the railway modelling community two manufacturers are offering us R-T-R 57XXs in 0-scale.
Dapol's model will be coming very soon but for now we shall be taking a look at the offering from Minerva Model Railways which has a RRP of £265 or £390 for DCC fitted.

Liveries available:

• GWR green with 'Great Western' lettering (unnumbered)
• GWR green without emblems (unnumbered)
• BR black with early emblem (unnumbered)
• BR black with late crest (unnumbered)


Minerva's packing is recognizable by the red and white coloured cardboard box which illustrates a side-on graphic of the locomotive enclosed. Opening the box the first thing you'll find is an accessory pack which contains:

• Vacuum brake and steam pipes
• Toolboxes
• Old and new style footsteps
• Bunker footsteps
• Cab roof handles
• Bunker top lamp iron
• Short and long whistle shields
• Moulded ATC (Automatic Train Control) box
• Bucket and fire irons

The model is cradled in soft black foam with plastic sheeting to prevent any rubbing/scuffing on the paintwork whilst in storage.


The amount of detail that Minerva have placed into this model is just incredible.

Moulded detail includes:

• Rivets on the cab roof, chimney base, on top of the water tanks, smoke box front and sides, all 4 sides of the cab, all 3 external sides of the coal bunker, the top and sides of the running board, buffer beams and access steps.
• Leaf spring suspension behind each wheel
• Ventilation hatch on the cab roof
• Sandbox lids on the running board
• Lower firebox detail between the center and rear wheels

Separately fitted detail includes:

• Water filler caps
• Water tank overflow indicators
• Standard 'Great Western' double whistle valves
• Handrails on the top, front and sides of the water tanks, cab sides and rear and the running board.
• Water injector pipe work on both sides of the firebox
• Water pipe slung under the water tanks, connecting them together
• Metal linkage for the reverser and sanding gear
• Metal rings in all 4 corners of the water tank top, which would be used in reality to lift the water tank off the boiler
• Lamp irons
• Smoke box dart handles
• Storage hooks on the cab rear
• Sprung buffers
• Sprung coupling hooks with screw—link couplings
• Sand boxes front and rear
• Brake shoes and roding

The cab interior of this model looks amazing. Copper pipework is present together with dials which have decals applied to them. Also on show is the regulator, steam and handbrakes, reversing lever, sanding lever, water gauge glass, water injector controls and the ATP (Automatic Train Protection) system. The lever for the firehole doors is also present with the doors in the closed position. The cab windows are flush with the walls and the rear windows have fine metal grill protectors fitted over them.

Livery Application

The GWR dark green is presented accurate and is really set off by the bright red buffer beams. With the exception of the route indicators on the cab sides there are no other printed decals, nor are there any etched numberplates, however Minerva are collaborating with Narrow Planet to offer customers the chance to choose which member of the 57XX class they wish to have by allowing them to decide what numberplates they desire.

When it comes to decals, it is left to the individual to decide which supplier they wish to go with. I would personally recommend Fox Transfers who offer a wide range of decals covering all the major companies across a vast range of eras in the history of Britain's railways.

Special Features

The model is wired up to take an 8-pin DCC decoder with space also provided for those wishing to install Dcc sound.

One feature I wish had been included, but sadly isn't present in this model, is a flickering light effect in the firebox, similar to what Dapol include with their 0-scale steam locomotives.


The heart of this model's propulsion is a powerful high-torque motor with a brass flywheel, all connected to the rear axle.

For slow-speed performance the loco is fitted with 40:1 ratio gearing which makes for fluid smooth running even at ultra slow-speed.

When it comes to strength the model is constructed with a die-cast metal chassis and footplate. This combined with the weighty motor assembly means that the loco has more than ample pulling power.

After the initial run-in period we tested the model's strength by having it haul no less than 6 B-set coaches (a 4-coach set and a 2-coach set) plus a milk tanker. The couplings were at their maximum extension but the model pulled the train with little to no wheel slip.

Final Thoughts

We got an idea of the high standards Minerva puts into their models when we reviewed the E-class Peckett and I'm pleased to say that those standards are still high with the 57XX Pannier tank.

The highly detailed body together with the excellent quality motor assembly and immense tractive effort makes for a model that every 0-scale modeller/collector, who have a passion for all things 'Great Western', will want to get their hands on.

It'll certainly be a challenge for Dapol's forthcoming 0-scale 57XX to match what Minerva has done here.

Watch this space.

Pros & Cons

• Exquisite detail both moulded and separately fitted • High quality build • Smooth running performance • Immense strength
• Lack of flickering light effect in the firebox

With this I give an overall score of 9/10
