A disaster on the Polar Express Layout – I made a silly mistake, and it proved very expensive. When connecting a new Lionel GW-180 transformer to the accessories circuit on my layout, I inadvertently reversed the polarity – connecting positive to negative and negative to positive by mistake. When I turned on the power with the polarity reversed, it blew-out all of the accessories connected. Seven remote control Fastrak switches were destroyed. I now have to replace all of them. I bought the new switches online from Grzyboski Trains (link below). The Lionel GW-180 transformer was purchased from Trainworld (link below).
