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 If anything it has superseded any expectations (by myself anyhow).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).
