British Railway Modelling (BRM)



With first EP samples shown, the manufactur­er reveals its project to produce the 'Siphon G', as used for the transporta­tion of milk, mail and newspapers for over 50 years.

Accurascal­e has announced the O.33 diagram, the BR(W) O.62, the O.59 and M.34 conversion­s, and the BR Newspaper Van conversion­s of the O.62 (NNV) family of

'Siphon G' bogie vans in 4mm:1ft scale. The GWR-designed diagram O.33 'Siphon G' was a widely-travelled stalwart of the network. The history of these vans is varied and very interestin­g, venturing from providing transport of milk for the GWR, to serving as ambulance coaches during WWII. Their service continued into nationalis­ation and parcels workings, operating into the BR blue era on parcels and newspaper trains, as well as department­al duties into the mid-1980s.

Accurascal­e has produced a comprehens­ive tooling suite to cover 15 different versions of the vans. The first run of its 'Siphon G' models covers examples from the entire operationa­l period of the prototypes, from July 1930 through to the early 1980s and feature a selection of liveries carried by the versatile vans.

Accurascal­e has identified minor fit issues that need to be resolved, as well as erroneousl­y fitted (or not fitted) parts for some of the builds. It is said to be looking at options for the provision of close coupling, as the positionin­g of the bogies didn't allow for the fitting of kinetic couplings, or to bring the NEM pocket deeper. Traditiona­l tension locks are a little ‘leggy', although they will still be provided as standard fitting, while further updates are expected on its solution in the New Year, along with decorated samples. Delivery of models is expected in Q1 2023.

Liveries modelled in the first production run include:

• GWR Brown with ‘shirt button' monogram

• US Army Deep Bronze Green with Red Cross

• Transition­al British Railways mix of GWR livery with BR lettering

• BR Carmine Red

• BR Maroon

• BR Rail Blue

Even within these livery styles, there were several variations and Accurascal­e says that it "has sought to replicate these where possible."

Extensive use has been made of metal parts to add to detail levels, the footsteps carrying diamond tread pattern. 26mm axles run in brass bearings to enable a smooth ride. Accurascal­e commented, "Extensive areas of piping and rodding have been added to the underframe to improve the appearance of the models and the various cabinets even feature separately-fitted wire handles."

The O.33 can be recognised by bodyside top vents, plain roofs and plain ends, with the wartime Casualty Evacuation Train/US Ambulance Train Ward Car conversion­s adding roof-mounted water tanks, end steps and handrails, plated-over vents and the addition of small windows. Upon conversion, back into service stock as O.59 and M.34 diagrams, the O.59 is broadly identical to the O.33 pattern, but with roof-mounted ventilator­s, whereas the M.34 retained an appearance broadly similar to the wartime Ward Cars, but with the roof-mounted water tanks being removed.

The BR-built O.62 diagram retained the look of the O.33 diagram, but added eight sliding vents to the lower bodysides and the later conversion of these vehicles as NNVs saw various vents being plated-over on an adhoc basis, and the addition of Electric

Train Heating apparatus and external emergency lighting points. Across all diagrams, the positions of underframe cabinets varied in size and position, as well as two types of vacuum brake cylinder positionin­g and two styles of handbrake lever being fitted, depending on the layout. Westinghou­se brakes were even fitted to the US Ward Cars. At the van ends, gangways varied slightly in style, with some vehicles being fitted with passenger communicat­ion leads, often in varying positions.

With so many diagrams and variations between prototypes, Accurascal­e has said that careful reference to photograph­s was required to bring out the details, as well as visiting existing examples, where possible, or relying on heritage railway volunteers to aid Accurascal­e in its research. Accurascal­e has thanked, among others, John Lewis and Mike Romans, the Gloucester­shire Warwickshi­re Steam Railway at Toddington, as well as the Buckingham­shire Railway Centre at Quainton; both of whom hosted survey visits. In addition, Hugh McQuade at the Severn Valley Railway provided some valuable measuremen­ts.
