Greetings my railroad friends. I have for me a real puzzler on a 2046 tender. Today I went into my archives of Lionel of post war trains that have been stored for quite some time. I started with a 665 engine and 2046 tender which were hardly ever used. I took engine apart and cleaned, oiled, lubed all that should be done and engine ran as if from the the factory. I also did the same with the 2046 tender. Observation and puzzler---when tender is alone on layout track or even with engine in neutral and powered the whistle is unbelievable and works great....HOWEVER when I run the engine and tender either alone or with lighted passenger cars the whistle does not whistle. If train stopped in neutral as I said the whistle works perfectly. The whistle relay works fine as it should but never in all my years have I had something like this occur. More frustrating than anything. I serviced the tender as I did the engine so it is and should be in great working order which it is IF in neutral and whistle activated. I even tried it with other engines and same thing. For power I use a post war ZW .....any simple ideas or easy fixes? Puzzler is as I mentioned when stationary it works perfectly and loud----rollers and solder points and wires are like new. Thanks for any thoughts.
