Model railroads come in all sizes – so should their power supplies! Lionel’s new GW-180 transformer offers a step up for layouts that have outgrown their starter set power supplies.
Engineers who have been running with our CW-80 transformers found in today’s starter sets will have no trouble learning the controls of this new transformer. The power lever, bell, whistle and direction buttons are all in the same place. The connections for track and accessories are the same as well.
The only external difference is the external power pack which plugs into the back of the control box and your wall outlet. This pack boosts the power from 80 to 180 Watts – offering a full 10 Amps of power to run your trains and accessories. (See our Understanding Electricity page for a review of these terms.)
This means more power for your growing empire. Lighted cars, operating accessories, powered switches, even multiple locomotive lash ups will operate more reliably with this additional power. Of course, you can still optimize your power by following the many tips found on our Wiring Your Layout pages. And you can use this new GW-180 alongside your existing or additional power supplies as your layout continues to grow.
The GW-180 offers variable AC voltage for track power up to 18 Volts and additional terminals for AC voltage for your accessories. This can be set to any level (we recommend 14 Volts) just as with the CW-80.
Modelers have been requesting a mid-sized power supply like this for quite some time. The GW-180 will be arriving at dealers very soon – just in time to start expanding on that set Santa brought! The GW-180 retails for $279.99.

I HOPE IT’S MORE RELIABLE THEN THE CW-80 WHICH ARE WORTHLESS . AFTER TWO SET I HAD TO REPLACE ONE WITH AN OLD RELIABLE TRANSFORMER AND NOW AGAIN WITH A CW-80.
The new CW-80′s are actually very nice power supplies. The first run had some problems with the phasing of the posts that has since been fixed. I’ve run some hefty Post War stuff with a CW-80 on a display layout for hours at a time, weeks on end without an issue. The GW-180 uses a proven platform in the 180 PowerHouse, and should be a good reliable transformer.
Why can’t these transformer be opened up to easily repair like the ones from the good ole’ days? Back then, a fuse blew, you open it up, fix and you are back to running. These days, fuse blows or shorts out and you’re hosed and this ends up in the trash.
Keith, we are required to build in these safeguards to prevent electrical shock.
KEITH, THE CW-80 CAN BE OPENED WITH A TRIANGLE SCREWDRIVER .THE ONLY THING YOU CAN CHANGE IS INLINE FUSE WHICH NEEDS TOO BE SOLDERED IN ,
I think Lionel should also release just the rheostat as a separate sale item (reasonably priced). It would allow the use of the thousands of 135w and 180w “bricks” already out there to be utilized even more.
are they suitable for 50Hz yet or still limited to 60Hz
It is still designed for the 60 Hz market. You’ll need a converter for it to work properly on 50.
Thanks .. i’ve already done this. Decided to use other controllers based on 50Hz, which has meant that I’ve had too update some of my engines to get smoke generation to work. Any plans for Lionel to go more global? Here in the Uk, Lionel is not really available at all, which is a shame.
The current CW-80 is “QC-50″ rated, and this CW-180 is new.
So, I don’t understand the “still” part of the question.
