Introducing the New Dublo ScaleBy the 1930s Frank Hornbys “0” Gauge train system had grown considerably both in the large number of items available and in popularity but new houses were by that time being built smaller than they had been previously and consequently limiting the space available for amongst other things an “0” Gauge train layout. Consequently, such restriction on space had an influence on the sales of Hornby”s “0” Gauge trains.In mainline Europe a smaller gauge was being developed which was half the size of “0”. This new scale was aptly classified as “H0” as it was half the size of the “0” Gauge models.Faced with this potential competition, the Meccano Board in 1937 decided to introduce their own system but due to scale versus mechanical size restrictions they could not quite produce an “H0” system but opted for a slightly larger scale which was given the name “Dublo” by Meccano”s Commercial Director. The Hornby Dublo scale used more or less the same wheel back to back measurements of the “H0” system but generally speaking all other dimensions were increased by 0.5mm.LNER Class A4, “Sir Nigel Gresley” – The First Hornby Dublo Passenger Train SetBy 1938 the first adverts started to appear promoting the new Hornby Dublo system. Two locomotives were initially produced one of which was a generic 0-6-2 freight model and available with GWR, LNER, LMS or SR markings while the other featured the LNER Class A4, “Sir Nigel Gresley”. These two locomotives were available with either a clockwork mechanism or a 12vDC motor and both featured in individual train sets where they shared a common pack.This celebratory set goes some way to replicating the first Hornby Dublo 1938 passenger train set. The stunning and heavily detailed LNER Class A4, “Sir Nigel Gresley” illustrates how the design and scale integrity of model production has developed over the years. Similarly, the Gresley teak effect coaches that are of a different type to those produced in 1938 show the amazing advances in model production since the launch of Hornby Dublo”s 1938 train sets.Limited Edition for Hornby’s Centenary YearThis limited edition of 1000 Hornby Dublo “Sir Nigel Gresley” train set forms part of the Hornby Trains Centenary group of products and celebrates the 1930s decade by using artwork inspired by the Hornby Dublo packaging style of that period. Included with each set and as authentication is a numbered certificate confirming the quantity of limited edition sets produced.What’s in the Box!?Rolling StockLNER A4 Class 4-6-2 4498 “Sir Nigel Gresley”LNER 61″ 6′ Gresley Corridor Third, 1434LNER 61″ 6′ Gresley Corridor Composite Brake, 58700Track & Accessories3rd Radius OvalTrain Controller (R7229)Wall Plug Transformer (P9000W)Power Connecting Track (R8206)RerailerUnboxing The Sir Nigel Gresley Dublo Train SetIn this special episode of Hornby Signal Box, Mike unboxes and takes a closer look at the Sir Nigel Gresley Hornby Dublo Train Set.”
