Has anyone seen a schematic for Lionel's CW-80 transformer???
The fan in mine is starting to make noise...
Why do you want a schematic to fix a noisy fan? Just open it up and oil or replace the fan.
I thought the schematic would be useful in determining the correct part number...
Figured the extra knowlege wouldn't hurt...
Might help. There's a website somewhere that has a lot of instructions from various manufacturers in various scales. I've seen it, but don't have the URL off hand, sorry.
Maybe someone else knows what it is.
Internal parts for the CW-80 are not available from Lionel, as it's not considered a "user repairable" item. That said, the fan is just one of those 12VDC sealed bearing mini-fans used in many computers. The trick is finding a triangle tipped screw driver to open the case with! ;^)
When they show up at my LHW, I plan to replace my CW-80 with one of the new Atlas-O 80 watt transformers that don't need a fan. Plus they allow "common ground" wiring of track and accessories like the older Lionel transformers did.

Not a problem; just make one from an old screwdriver by grinding a three-sided shank. I've done it.
How do you think I know the fan is just one of those 12VDC mini-fans?? ;^))
Thanks to all who responded...
And, yes, after much searching of security head screwdrivers I've decided I'm gonna have to grind my own...
As to the CW-80, I've tried hooking up a couple of independently powered accessories & computer sensors to the accessory jacks with just miserable results.
I'm thinking a common ground transformer referred to in an earlier post may be the ultimate answer to my problems.
