Hot off the Press - Hornby at Warley National Model Railway Exhibition 2014
As we speak (10.00am Saturday 22nd November 2014), the covers are coming off the Hornby stand at The Warley National Model Railway Exhibition.
Hornby will also be revealing a rapid prototype model - a highly detailed 3D printed version - of the newly announced King Class. (STOP PRESS - the above models and the King are now all available to pre-order).
The quest for accuracy reaches unprecedented levels this year as the Hornby team have been utilising 3D scanning of real locos in preservation. LIDAR scanning uses laser light to accurately map the surface of an object in three dimensions, resulting in a high-definition 3D computer image of the object. This image can then be fed into the Hornby CAD system, enabling us to produce incredibly detailed models directly mapped from a vehicle, rather than recreating the shape from other sources such as blueprints or photographs.
The laser scanner is placed around the asset in as many as 40-50 positions, from both the ground and a raised platform such as a scissor lift, in order to get the best coverage. The scanner rotates, sweeping the area with a laser, which is constantly taking measurements throughout the scan. As many as 5 million points are mapped in each sweep, producing a 3D image with detail as small as a fraction of a millimetre.
The next step is to align all of the separate scans, then clean out all unwanted material, such as the surrounding area, people and any errors caused by reflective and refractive surfaces such as glass and mirrors. Finally, this point cloud is then converted into a solid polygonal mesh object, ready for us to use as a template for the Hornby CAD system.
In the case of the newly scanned Class 71 at Barrow Hill (due for delivery in 2016), we have gained permission to recreate the exact livery of the preserved model. The British Rail Class 71 Electric Locomotive is a Bo-Bo configuration engine, built at the British Rail Doncaster works between 1958 and 1960, for service on Southern Region’s Kent Coast Main Line .
The Class 71 was only able to work over the third rail power system in service, which ultimately limited its operational scope for passenger and freight work. Despite this restriction, the engines worked high profile routes, notably the Night Ferry and the Golden Arrow.
See below for detailed CAD images and a render of the Class 71 in development.
New for late 2015, the Adams Radial (now available to pre-order) was designed by William Adams and introduced in 1882 for service on the London and South Western Railway (LSWR). Originally rostered for suburban traffic, the class was soon displaced to the countryside by Dugald Drummond's M7 class. Most of the class was scrapped around the end of the First World War - one has survived and can be found on the Bluebell Railway, which is the locomotive that has been scanned by Hornby.
Finally, some new rolling stock due early 2015 - the LMS Horse Box and the BR 21T Hopper - both available to pre-order now.
During the show, the Hornby team will be on hand to answer questions at stand B25 but for those who can’t make it or think of another question Andy York is organising a Q&A session via RMWeb which will be answered following the show, and the publishing of Hornby Plc interim results on Friday 21st November.
“We recognise that some new entrants to the market have announced their intention to do particular items that Hornby has done in the past or will be doing in the future. History tells us all that competition is usually very good for the consumer, and ultimately they will decide which companies thrive. We have had our challenges in recent years but we look forward to 2015 with optimism.” said Nathaniel Southworth, Sales & Brand Director at Hornby Hobbies.
We hope this has whetted your appetite for the 2015 range - the full Hornby 2015 range will be unveiled here on 17th December 2014. Look out next week for more news and photos from the weekend at Warley.
