The B17 SLT engineering team have commenced discussions with potential partners for the various items of the rolling chassis prior to placing orders, while we await Ricardo Rail Ltd. of Derby's approval of the design definition for this next phase and other required documentation.
Primarily these are the Horn Blocks, the Cannon Axle boxes, Axles, Tapered Roller Bearings, Driving Wheels and Tyres.
Examples of the CAD drawings are shown here.
