Sounds like the "variable resistor" that allows for a variable speed is either defective, or has become corroded on it's switch contacts. You might get lucky with some electrical contact cleaner spray and spraying it in or around the variable speed switch. Otherwise, I'd just invest in a new transformer.

Want to use this on 220v aussie supply to power 1947 221 lionel train loco Suitable?

ohh no that id not try at all , one can first use a power converter that one can buy off many online sources to convert 220 volt down to 110 volt then to transformer this will be safe 4 unit, the 50HZ to 60 Hz doesn't matter to much as well unless one plans on using the lionel sound generator , then its not gonna sound to spry as it will be a bit slower !!

Lionel legacy will not run more than 2 trains

see pages 44 & 45 of attached pdf to figure out your power requirements for all locomotives, lamps/light bulbs & accessories.
compare total needed to power output of your transformer, if total is less that output of transformer, clean wheels, roller pickups & track.
if total is greater than output of transformer, you need more power/larger output transformer. lean wheels, roller pickups track.

The train keeps jumping off the track

Is the track properly and carefully put together? Is one or more sections damaged take one of the cars and gently push it around watching in those places where the train derails. If it only happens at a track joint look at it more carefully.

Piolar Express front pivot hangs and causes derailment

There is a design flaw with the spring loaded pivot. If the wheels canter even the slightest, like on a turn, the mechanism slide locks up. I solved this problem with a medium white lubricant used for fishing reels called lubriplate. Make sure you lube both sides of the slide. Other medium consistency lubes should work just as well.

Can I use the cw-80 transformer on any Lionel train set from year 1948 to the preasant , thanks George

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.

My new lionel train slows down on far side of the track

There is bad contact in the track connections. You can sand the track connection sites. Another method is to run another power wire to the other end of the track where the train slows down. Even better is 3 or 4 evenly spaced power wires from the transformer to the track.

We just got the Hogwarts express and it will not complete 1 loop without derailing or the cars becoming uncoupled.

Well you should probably check the radius of your curves. The Hogwarts Express has a minimum curve of O36 and on a tighter radius curve it will derail. I have found that the Hogwarts train runs better on fasttrack than standard O. You should also make sure the track is flat because if it isn't completely flat it derails. The train isn't designed well so it derails but if you run it slow you shouldn't have a lot of problems.

Yes. Find a Lionel repair shop or bring it to a local hobby store that does model train repairs. You can contact Lionel for a list of repair shops.
