Jim Brenner posted:I've also had difficulties with mine, but have had some success by replacing the bulb. It seems that the dimple on top of the bulb can be an issue. On the advice of the dealer, I bought three bulbs at a show one time and, of the three, only one worked. The dimples on the other two bulbs prevented the lens from balancing which would not allow it to turn.
I think there is a lot of truth to this. I noticed after spinning mine by hand it came to an abrupt stop. I suspect when Lionel was having the bulbs made back in the day, quality control was much better. I doubt the new bulbs are even made here anymore. Be nice to find some new old stock to compare.
I have a 494 too but there is much more nostalgia in the 394 for me. Plus its silent.
