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.
