As anyone who knows me knows I have a soft spot for the LSWR I couldn't resist buying a Hornby version.
Now here's the issue, on DCC it's perfect,
it will crawl all day long. Putting aside that Two of the pick-ups were not touching the wheels. (Easily solved)
After being informed that I hadn't run it in correctly and that the carbon brushes needed bedding in, may be the case back in the seventies but knowing that most modern motors these days tend to have basically, two pieces of wire contacts made from a type of precious metal.
I watched this guy's video that explains all. Very well documented and informative.
Glad it's not just me.
