Hello I'm Jon found old locos in the house and have been living on ebay picking up cars and locos. I'm running 027 track with a basic transformer. I have a ZW but its internally shorted I believe and would like to fix it! But on another note.... a older Burlington Northern engine I took apart cleaned up serviced oiled all contacts and the "magneto controller" correct me if I'm wrong is buzzing very loudly when running. Is there a way to quite that controller or a way to upgrade this unit with a circuit board?... My son recently got me wanting to get into this more with his fascination for model trains went to the Strasburg RR Muesume and he lost his mind lol he's 2 and the buzzing just makes him lose interest.

Sorry rambling thank you in advance.
