I remember seeing this unusual engineering vehicle at Tonbridge when the line was being prepared for Eurostars. I found a 3D print available on eBay by ‘class_66_driver’. It is a fairly good representation but came with poor quality wheels. Replacing these with good metal wheels and pinpoint bearings required the model to have the axle mounting broken carefully on one side then be glued back on with the new wheels and bearings in place. Transfers are from Precision Labels.
