I have been chasing up Lionel on a monthly basis to find out if they have decided on a resolution to the Blue Comet "Whistle" issue. As you probably know the whistle on the Legacy version sounds more like a diesel horn than the beautiful whistle on their 2001 TMCC version.
Anyway, today I received an email back issuing me an RA number and asking to send the tender back. The woman on the line couldn't tell me exactly what the fix would be but assumed it would be something like replacing the sound board.
Anyway I really hope that if it is a sound board replacement they don't simply use one from another existing engine like the Southern Crescent, but instead replace it was a Blue Comet specific version.
The tender is now on its way to Ohio and I'll let you know the outcome when I receive it back.
Assuming it comes back sounding great I'd like to thank Lionel in advance for doing the right thing!
