Had a customer today report that after approximately 30 minutes of use on a large continuous run layout (Retford as it happens) his Hornby class 50 which has, incidentally, been easily converted to EM gauge, started screaming. Investigation revealed the problem was caused by dry bearings on the shaft drive to the roof fan, and was cured by a quick application of light oil.
Hope this tip might be useful.
Best wishes, John Turner,
