I have 3 second-batch MWs, all of which derail on some or other of 17 Mainline points. I have quite an investment in the L & B and want to make the locos work but do not have the skills to make the alterations suggested on this forum. Local model shops don't seem to have the experience or enthusiasm for the task! How can I find an expert to undertake such work? Incidentally, a tiny Eggerbahn 0-4-0 sails through all the points but an equally ancient Roco 0-6-0 diesel derails on many of them.
