Hi all I have been handed back my childhood locos from about 30 years ago from my dad and have decided to build my 7 years old son a large layout (well I say for him maybe a little bit for me too) I want to be able to run several locos at the same time but can recall this being quite tricky with the old analog engines. Most of the locos are GWR stream engines with a few diesels. I spoke to my local model shop at the weekend he said that its a bit of a ball ache with N gauge trying to isolate the supply and they no longer do it as they kept burning the chips out. I was wondering if this is the case and also the approx. cost to do the job yourself? I can solder but I'm not the best in the world! Any advice is appreciated, I have about 8-10 locos Many thanks Darren
