Why does everyone refer to twin vertical motors as "China Drives"?

The vertical motor concept was started by the original Lionel company way back around 1949-1950.  Granted they weren't DC can motors but wound field universal motors but the basic principle is the same. The early Williams US made units had the same drive but just used an adapter plate to mount a Pittman DC can motor. Chinese manufactured units are far from the first to use this system.  I am familiar with brass and other manufacturer engines, horizontal motors and gear towers

My opinion is that a better "China Drive" description would be the small truck frame mounted DC motors used in the lesser expensive models.  I know what people refer to but if my history serves me correct the "China Drive" should be more aptly called a "Lionel Drive".

It is a derogatory term to describe a drive train that is similar to what is found in a postwar 623, 2028, 2321 and later F3's. The exception is that the vertically mounted 622-100M, 2029-100, 2321-100 universal motor is replaced with a permanent magnet can motor. As you stated, Williams started this practice back in the 1970's when they were made in the USA.  Thus, the more appropriate term would be "American Drive". 

The vast majority of the time the term is used to described something that is bad akin to terminology used in WWII. Usually some other motor mounting system such as horizontal is "good" and "vertical (insert term here)" is bad. If "American Drive" was used then it would be akin to associating America with bad. 

You are completely correct, the design dates back to the late 1940's and was not produced in China until decades later. 

Actually, I like the simplicity of the vertical motors.  I just wish they could provide slightly better gear ratios for low speed performance.  I don't know anyone that comes close to exercising the maximum speed, they'd be constantly picking up the derailed locomotive if they did!  I've never been a fan of the horizontal motor as it takes up all the space in the shell and doesn't allow for the electronics.  One only has to see some of the convoluted solutions to fitting TMCC into Atlas switchers to see what I mean!

Yep! And the slammed "China Drives" work fine, especially with modern systems, like DCS or TMCC/Legacy, as it's never been the motor orientation that's the issue, rather the drive gear ratio.

I have to agree with WBC on this in that in the O scale world, the term “China Drive” is not used as a term of endearment, usually its used when trying to compare a brass model loco to one recently made by (Lionel, Atlas, MTH). You can walk the halls of the O Scale March Meet in Chicago and hear the term used in discussion often.

While I don’t have a problem with the misuse of the term, (I understand what the speaker is talking about), I do have to raise an eyebrow to the comments made that horizontal motors are “usually” better than China Drives. When I hear that I know I am hearing a collector and not an operator.

If horizontal drives were always so good, then we would see better running O scale, two rail locomotives… and we don’t!

A properly made horizontal drive is just as good as vertical “China Drive” in terms of operation and vice versa. Crappy made horizontal motors/gear boxes and crappy made “China Drives” are both still crappy.

The one area that a good or properly made horizontal drive motor was superior was the slow starting performance. However, recent electronics have greatly evened out that advantage. Once running, there is no operational difference.

Currently, I have both types of drives in recent manufacturing and I can measure the slowest running, smoothest loco and it is not the horizontal drive locos. So in practical terms, there is now, no operational difference.

The horizontal drive is superior for hiding the motors in diesels, allowing room for detailed interiors.

Now, there are other pro and cons of each drive system that might be of interest to the person making a purchase, and in those cases, “China Drives” might not be the best answer.

I agree. I do not care for the driveshaft diesel setup; I've had 2 fail (Lionel Alco switcher, catastrophically; 3rd Rail Dash 9), and never one failure of a vertical motor drive. Good gearing is always better, of course.

- For no particular reason I do not use the term "China drive". Maybe because it's not descriptive. I tend to say "vertical drive" or "vertical motor setup". Maybe it's because I have mostly steam locos, so, not relevant. (Wrong! See ROW, Lionmaster and RK articulateds - all vertical drive diesels/electrics in drag.) 

- "Why does everyone refer to an Internet search as aGoogle Search?" Well, I don't; never have. It's just a "search". But, I have never been a big user of Google (dislike the name, too); Netscape, Safari, IE (I think) were my first browsers. I prefer Safari, as I recall. Mostly I prefer not being on a computer, but here I am.

Rambling over.
