Question about Lionel Cw 80 Transformer
The voltage regulator is part LM78L05. You might want to check the two diodes are ok as well 'D1' & 'D2', sadly I can't see markings on them.

I have had the same problem with my polar express, which i just bought recently. Having to send it to the USA from the UK would be very expensive so i decided to open it up myself. The tamper proof screws were a bit of a problem getting into it. I ground down an old screw driver into the triangle shape to undo them. I then replaced them with self taping srews the same size.
The Problem I found was simple, there is an internal (250V, 8Amp) fuse soldered onto the red wire on the secondary winding of the transformer. The red wire going from the transformer to the PCB, the fuse has black heatshrink over it.
There is no room inside the housing of the controller to fit a fuse holder. I fitted a box on the side of it with a panel mount fuse holder. drilled a hole through the housing, fitted longer red wires, so they could go through to the terminations on the back of the fuse holder.
At least now I can change it simply if it blows again.
hope this is of help to you.

It sounds like the variable resistor control is faulty or shorted, and supplying voltage all the time. If the unit's new, enforce your warranty or exchange priviledge. This problem shouldn't be happening for a few years.
If, for some reason, your warranty doesn't apply, you'll have to take it apart to figure out what's broken or shorted.
I would contact Lionel, if worse comes to worse- maybe they would send you an exchange.

Good luck, and hope this helps.

SOURCE: Can I use the cw-80 transformer on any Lionel
You should be able to. The Lionel transformers all put out AC power, not DC and many Marx and American Flyer transformers will work too. The real question is total amount of power being drawn and whether or not you have the wattage to match your engine and accessories. With the CW-80 though, it should put out plenty. I run my pre-war 1666E engine pulling a full compliment of metal cars with no problems using a CW-80.

The CW-80 is not suited for electronic sound systems. The output is non-sinusoidal. When electronic sounds are generated for some locos, the sound will be garbled. Use another power source. The Z1000 MTH power source or similar is recommended as are many other older Lionel standard power xfmrs. For the sound stay on problem with switch off, try putting a fixed load on the tracks ie: An accessory of some kind (lights etc). Usually a fixed electrical load will fix this problem. Overall, I would recommend changing out the power source and save yourself a lot of headache..
