My recently arrived Lionel 636W (w/ 637 and 638 cars) "City of Denver" streamliner on the layout. The engine is a repaint (although very tastefully done) while the cars are original with a few minor touch-ups. After a servicing and replacement of a broken swivel pin, it runs great. After cleaning the contacts and getting the reverser to cycle more reliably I decided to just lock it in forward with some tape to add to my enjoyment of watching it run. Whistle still needs attention- the contact picks up very reliably and it makes sounds, but not exactly "whistling" yet. A question- how do you get to the bulb inside the observation car?
