Nice quality model, and a really good free roller too. A nice addition to my GWR coaches.

Excellent Model

Ordered from Accurascale and delivered quickly. A detailed and well made model that fits perfectly with my other GWR rolling stock. Delighted with my purchase

Fine detail

As with every item I have purchased from Accurascale this is first class.
Never a hint of derailing, smooth running and incredible detailing.

Another siphon

I already knew that this was an excellent model, having previously bought a BR maroon and BR crimson version. This runs beautifully behind Anthony Manor.

Superb model

The detail is exceptional and the running quality is excellent. Magnetic couplings are a good idea as a spare. Looks beautiful behind my Accurascale Zmanor.


Wow. My 8th and 9th of these waggons. Thies time in brown livery
. I now have all liveries except the medical one and they are all great. Buy some whilst you can !!!!

Gods Wonderfull Railway "Siphon"

Fantastically detailed model and nicely weighted, the detail is so good that one can not use a back-to-back gauge, LOL I like the inclusion of the magnetic couplings, a well-deserved five-star!!
As an aside, we now have several of your Siphons running at the Waverley Model Railway Club in Melbourne Australia. Kindest Regards Noel Anderson

A new standard for RTR rolling stock.

These were very hotly anticipated by many including myself, and often when a model has high expectations prior to delivery they can fall short of what was expected even if they're a brilliant product. This however has not fallen short. If anything it has superseded any expectations (by myself anyhow). The detailing is incredible, the livery application is crisp and the right colours, the underframe is mind boggling, the running characteristics are smooth and effortless, and the packaging is substantial enough to withstand anything that even the clumsiest of delivery drivers could throw at it. My only issue was with the supplied magnetic close couplings, whilst in theory they are good and I like the functionality of them, the magnetic force is slightly lacklustre, and any minor jolt was splitting them, so I've just replaced them with some Kadee 18's to get the same effect. Despite this, the Siphon G is a firm favourite, and has fitted into my layout beautifully.

If this is a new standard within the railway modelling, it is nothing short of fantastic, and should be commended (so that others can hopefully follow suit).

More Great Western please Accurascale!

A new level of quality and detail

I have the Lima version of the Siphon G back from my childhood and the difference as you would expect is night and day, the weight and quality of the new model is very good and the price is reasonable too when you consider how many old tooled models are on the market for similar money. Thoroughly recommended!

Very great model

Only ran it a couple of times but very well detailed runs well, tempted to buy another
