I've seen the Lionel 2021 Catalog entry and what's on the Lionel Product site,

CW80 Transformer (New & Improved) SKU: 1908080

http://www.lionel.com/products...ew-improved-1908080/

80 Watt AC power supply
Throttle lever to control speed and power. Operate your favorite features with the bell, whistle/horn, and direction buttons.
0-18 volt variable programmable AC output for accessory operation

Compatible power supply for:

    LionChief
    LionChief Plus
    LionChief Plus 2.0
    Legacy
    Traditional transformer locomotives
    Plug-Expand-Play Accessories
    Traditional Accessories
    Built-in circuit protect for derailments and shorts

PRODUCT SPECIFICATIONS

    Rail Line: Great Northern
    Road Number: 246
    Power: Electric
    Dimensions: Length: 14"



This information still leaves me wondering what, at it's core, will be different from the older CW80 and what other Improvements it will have.

For instance, does it still use a switching power supply for it's AC output or does it use a variable transformer output like it's Postwar siblings?

Will it cause issues when connected to a Powermaster (the possibility of "unpredictable operation" like the 6-14198 CW80)?

How fast does it disconnect the output in case of a short circuit and does it use a relay or solid-state circuitry to break the connection?

Does it have built-in TVS (Transient Voltage Suppression)?

An Internet search has not revealed any more information about the new CW80.  Does anyone here have more definitive information about this Product that I've heard rumored to be available this fall?

I think @Dave Olson is your best source to find answers. I know Dave has mentioned the new CW-80 before on the forum I do t remember what thread I’d have to go searching but I do remember some.

from what I recall it is very close to the new PH180 power supply so it will no longer need the cheep fan that makes a lot of noise. And it will also be UL approved (if I recall correctly) so I’m sure there a LOT of little things we might never think is necessary that UL will require

Zachariah, Thanks for the tip.

Going back to Jan 2020, the only mention of Lionel transformer details by @Dave Olson I found on OGR was in the discussion of the third pin safety in the Molex connector of the new PH180 which UL requires (for a load to be connected before turning power on AC Voltage at the output).  It stands to reason that the new CW80 (no hyphen) would have the same UL requirements:

Are there any other Improvements to the new CW80?

I suspect until it's in folks hands and maybe someone takes one apart, we won't really know what has changed.

John, you may very well be correct.  Since I've read in a few recent posts that some folks may be postponing buying a transformer to power their upgraded layouts, expecting the new CW80 to meet their needs, I thought posting on the Lionel Products forum and asking these questions might yield some insight, and help people decide if it would be worth the wait.

Hopefully Dave @Dave Olson will provide some additional answers about the New and Improved CW80?.
