It really is November.Had my last day of sailing RC model Park where we go sailing is down to almost winter levels so it is hard to sail a boat without getting stranded. Now for the real weekend part of my thread (post). After finally getting all the electrical problems that my layout was having fixed,I held an OP Session did it on a Saturday not the usual Sunday schedule. Spent 48 hours before the session installing more Fox Valley metal wheels to the fleet of cars that are perminantly out on the layout and used at the sessions,with car cards. Now my fleet is about 80% converted. The engineer on the branch line train was trying to switch the cars on to the proper tracks in the interchange yard for pickup and delivery by Eastbound and Westbound freights to the main yard to go off line ,he found he was having his locomotives go dead this had not happend before. The problem was soon discovered to be those new metal wheels and gapped track. Don't park cars with metal wheels on a gap or with one end on either side and expect the switch when thrown to work correctly. Nate Goodman (Nato).
