Gentleman I wonder if you can give me advice as to where I can get spare parts for this lovely model. The image below is where my problem lies. Axle has started to arc on the lower plate causing a short circuit. I need to replace this whole Bogie A- D complete. #L33985 910-2

I also need a set of Driving wheels. Cog slips on axle: #L33985 910-1
Look forward to your input & suggestions.
