What are the differences between the Lionel, Atlas and 3rd Rail F7's

Are you asking about the differences in the command control systems, since you posted this on the Lionel TMCC and Legacy Forum?

Or, are you asking about the individual details of a specific railroad, between the three?

Both, I am looking into the Santa Fe units.

OK. The Lionel units obviously are Legacy control, while the Atlas and Sunset/3rd Rail are TMCC by Electric Railroad (cruise commander).

Concerning the various opinions of details between the Lionel, Atlas and Sunset/3rd Rail, you might want to use the Advanced SEARCH function, as there have been countless discussions/opinions on all three brands (especially on the 3RS Forum, as I recall).

Lionel does not have the stainless steel simulated plated sides.  3rd Rail and Atlas have been debated a lot on the forum as noted above, but the main difference there is the Atlas version has vertical can motors to each truck like most manufacturers, while the 3rd Rail version has the large horizontal can motor driving all wheels through a worm.  It has a more realistic top speed and is better at slow speed running.  It also cost more. 

I won't wade into the debate more than that as I'm biased on my selection.

Not a direct comparison but a thorough  review of the Atlas O version which will assist in making your choice,

Good Luck, Mike

How does the minimum radius compare between them?

Thanks every one for the info.
