Model Steam Engines: Explaining Scales
Model steam engines are manufactured according to a variety of scales and gauges. The choice of scale and gauge is crucial as they are the major differentiating factors between the model steam engines. What makes things more confusing is that many model steam engine enthusiasts, and even seasoned fans, often use the two words ‘scale’ and ‘gauge’ interchangeably. However, they are two distinct attributes. For starters, scale establishes the size relationship between the model engine and the real one. It is often represented as a ratio, such as 2mm:ft or 1:148 scale. This means that every part of the model engine is one-one forty eighth the size of the original steam engine. On the other hand, gauge is an attribute of the railway track. It is the distance between the inner edges of the track rails. Gauge is a more important attribute to consider, when purchasing a model steam engine. Let us understand why by looking at the main gauge types. O Gauge O Gauge model engines were produced from the beginning of the 20th century, and were among the most popular models for a long time, until the 1960s. Since then, they have lost their popularity and are difficult to find. They were manufactured in multiple scales from 1:1.48 to 1:43.5. But, they eventually lost their fame to smaller scale models. O Gauge model steam engines are not known for their finer details and accuracy. In fact, they were designed for pre-adults and therefore, cost-effectiveness, and durability were given more importance. Although they are valued by some collectors because of their rarity, most of the collectors and enthusiasts, with an attention to detail, do not prefer these models. OO Gauge OO Gauge or Double-O Gauge model steam engines belong to a family of model railway systems, which follow the standard gauge model. The OO Gauge has a railway track that is 16.5mm wide, and is built at a scale of 1:76.2 or 4mm:ft. A highlight of OO Gauge models is that they rank very high in terms of realistic appearance and finer details. For this reason, they are of great value to serious collectors. Moreover, many of the manufacturers also place a lot of emphasis on durability and affordability. Naturally, they are among the most popular model steam engine categories today. G Gauge G Gauge models are big in size. They are manufactured on a scale range of 1:22.5. Because of their relatively huge size and highly durable construction, they make the best garden railway models. Their extensive use as garden models have led to modern train enthusiasts to believe that the G in G Gauge stands for Garden. The truth is that the G comes from groß, which means “big” in German. Oh yes, the G Gauge models were born in Germany, just like many others. A large scale means that the parts are not as intricate as the other models, say O Gauge for instance. Therefore, they are easy to produce and are readily available. Final Thoughts As you can see, the choice of gauge will be quite obvious to you based on the purpose of your purchase of a model steam engine. If you want a garden mode, then G Gauge is what you need. If you are a collector who enjoys the finer details, then OO Gauge is what does the job for you. However, if you are buying a model engine for your kid, then O gauge is just the thing.
Review: Wilesco D5 Steam Engine Model Kit
Review of the Wilesco D5 Steam Engine Model Kit This is a gorgeous, highly detailed steam locomotive engine that is also a working model that produces actual steam. It’s ideal for beginner steam enthusiasts, especially younger ones as it can be used by children as young as eight years old. There is always something very special about steam engines, and the way they powered the industrial age. Models like this are a good introduction to this time period, and a hand-on way to learn about history and engineering. If you are giving this to a child, bear in mind that it will require adult supervision and is most certainly not suitable for children under three years old. It is also a working steam engine and it does turn the flywheel quite fast. The D5 Steam Engine from Wilesco is in kit form, so you’ll have to assemble it, but that’s more than half the fun of having a working model. Assembly is straightforward; there’s an easy to follow manual, which includes illustrations so you don’t feel lost trying to work out what goes where. No soldering is needed; the components are put together by screwing them into place. It’s an attractive model, with a faux red brick platform and chimney stack, rather like a Victorian factory might have had. The boiler has a shiny, brass effect thanks to the nickel finish, as does the oscillating cylinder and the piston. There is also the red and brass effect fly wheel. There’s an inspection glass that is the water level indicator at the front of the boiler, with a dome steam powered whistle on top. The spring safety valve is also located here, and this is where you need to insert the water using the funnel. The piston and wheel generate power, and once in motion it gets quite a speed up. This is a noisy toy, and you do get a lot of steam, all of which makes it quite exciting to watch in action. The engine used a dry fuel to heat the water for steam. There is no need for additional batteries. It really does bring to life the age of steam, and it has identical specifications to Wilesco’s D6 steam engine. The D5 is the kit version, and the D6 comes fully assembled. The Wilesco D5 Steam Engine Model Kit is quite light, weighing just 739g. This is not a huge model, even though it is fully powered. But it is a good enough size for an entry level type of kit at 21 x 15 x 15 cm. It should be possible to use the engine to power small devices by connecting to a dynamo too. There are lots of possibilities, and you are only limited by your imagination. There are other Wilesco models that you can attach to the engine, and you can drive other Wilesco models from its range. Comes in kit form, no soldering required Has a brass effect boiler with nickel finish Boiler house has a brick finish, brass oscillating cylinder and also pistons There is a dome steam-powered whistle A driving pulley powers the flywheel Uses a dry fuel Weights 739g CHECK PRICES
Review: Mamod SR1A Steam Roller
Review: Mamod SR1A Working Live Steam Roller Young boys and older men who are interested in vehicles of all types are going to love the Mamod SR1A Working Live Steam Roller. This delightfully coloured model is a perfect replica of a 19th Century British Road roller and will provide males from every generation a chance to let their imagination run free. This is the perfect model for creating fun stories, characters, ideas and scenarios. Also, even though this is a boy’s toy, mums, sisters and daughters can still have fun playing and creating these wonderful stories and worlds as a family. The Mamod SR1A steam roller comes fully assembled, so for those of you out there who love the finished model product, but aren’t really too keen on the building process, this is the perfect model for you. Father and son duos looking to either build up an existing collection, or start a new hobby together can jump right into the fun. Due to this model not needing any assembly, it’s perfect for boys who are just starting out their model collecting hobby and because it’s suitable for ages 14+ for non supervised use, the worries of mum and dad concerned about what to buy their teenage son are no more! (Also suitable for dads needing an excuse to add to their collection!) As the pictures show, this model is exceedingly beautiful. The steam roller is simply designed using the most durable metal materials, giving the model a realistic overall look. A more modern and pristine look is given to the steam roller by it being finished with top quality colourful paint. (Get your hands on the model to help give it a more used authentic look! Real life steam rollers wouldn’t look this luxurious afterall. Of course, hardcore collectors wouldn’t dare ruin the exterior appearance of this fine piece, but that’s the beauty of the SR1A – it’s suitable for all!). The model’s dimensions are 255 x 177 x 144 mm, making it a perfect size to handle and not so big that it takes up too much room in a collector’s room. The Mamod SR1A live steam roller is exactly that – live! The model is fully functioning as if it were an actual steam roller used on the street. The model uses solid fuel tablets (which are much safer than the fuel used for models similar to these in the past) and water. Water is poured in, the burner is lit and the steam roller is set to go. Once the model is fired up, it can easily be controlled by using the steering rod to control the front chassis. The flywheel controlling the belt to the rear wheel is powered by a brass piston and cylinder, just like a vehicle in the real world. Steam rollers in real life obviously have the ability to move forwards and backwards; Mamod have put thought into this too, giving their product the ability to travel in reverse, as well as forward. What really gives this model a special touch is the sound it makes; because of the real life components making up the steam roller, the sound made mimics that of a steam roller of its time. This is made possible by the chimney billowing steam from the model’s exhaust unit. There isn’t a live steam roller quite like the SR1A on the market and the high quality materials making up this model ensure a longlasting product you’re going to enjoy today and for many years to come.

Review: Nanoblock NAN-NBM001 Steam Locomotive
Review of the Nanoblock NAN-NBM001 Steam Locomotive Although less well known than their competitors in the children’s building block market, Nanoblock manufacture traditional children’s model making kits using the ‘raised dot’ blocks which any child or parent will know well. This kit allows children to create a model of a tank locomotive – a steam engine without a tender, to you and me – and includes over 800 individual building blocks for just this purpose. Don’t worry though, it comes with instructions and a picture to follow too. Just as with all building block toys, this kit isn’t suitable for children aged under 3 years as they may choke on the pieces. The manufacturer recommended age group is from 12 years and older, with adult supervision. With that aside, however, it is sure to be enjoyed by young and old alike. Once built, the model depicts a black steam locomotive, pausing at a signal as it journeys along a railway line through pleasant green countryside. Youngsters will be enthralled by the romance and magic of steam, while the older generation will become equally fascinated by the details contained in the model and in reminiscing of times past. The 800 blocks included in this model kit are manufactured from the highest quality materials and are compatible with other kits in the Advanced Hobbies Collection from Nanoblock. You may also find that they fit with building blocks from a certain other well-known company. Playing with Nanoblock helps children develop their planning and organisational skills as well as encouraging creative play and building imagination. Children can use the included blocks to build anything that their imagination can create, and by extending the kit with other Nanoblocks, can stretch the limits even further. Unlike some cheaper makes and models of building block, Nanoblocks are carefully designed, precision manufactured and constructed from high-quality materials to ensure that you never experience the frustration of blocks sticking or not fitting. All Nanoblock products work together seamlessly and fit each other with perfection and precision to give the best possible experience when building. The steam locomotive model is easy to build following the included instructions and the picture on the box. You will be fascinated to see it develop, layer by layer, as you construct it and will end up with a model reminiscent of something from a Ghibli movie. The locomotive itself is in the Japanese style, with plenty of extra ‘knobbly bits’ and details such as coal in the bunker. Once the Nanoblock Steam Locomotive is completed, the finished item will look fantastic adorning any child’s bedroom (or an older child’s den) or can be taken apart and the blocks used to construct anything else that your heart desires. Key features: Over 800 building blocks included Full building instructions included in four languages Minimal and easy use packaging Manufactured from high-quality, long-lasting materials Combines with other kits from the Nanoblock Advanced Hobbies Collection Develops children’s imagination, creativity, organisation, and planning skills.
