I have basically the whole Blue Comet train with that oh so 70's campy sound of steam. Still works too. Not as bad as I thought it would be since it is rather mellow BUT since Lionel had issues with the electronic version of the whistle they had done away with it but the time this engine was made. I purchased a old tender whistle that works like a champ but can't seem to figure out how to remove the roof. Since these cars are lit with 2 bulbs each, they would eventually need to be replaced but I can't find anything on line showing how. Has anyone here removed the roof on one of these without damaging the car? If so, could you explain how you did it? Thanks !
