4.5v train motors with technic axles

[rsb0204]

I (and im shure many others) are fans of 4.5v lego trains. only thing is, they are quite slow. I know there were some 4.5v train motors like x469b that allowed the use of technic axles as well as the standard train wheels. that got me thinking, the new large train wheels that the emerald night, toy story, and lone ranger sets have use technic crosses, and I see no reason why they wouldent fit, so I wonder how a 4.5 motor would cope with them? im shure the 4.5v motor has enough torque to handle the large wheels. anybody tried it? and does anyone know if the gearing of the technic axle is the same as the train wheels on these motors?

every 4,5 motor can use any technic wheel by means of http://www.bricklink.com/catalogItem.asp?P=bb301 or http://www.bricklink.com/catalogItem.asp?P=pinpw2 or (only for the very first motor) http://www.bricklink.com/catalogItem.asp?P=bb301a.

I personally use this way with the emerald wheel and it's very fun. Also the 12volt motors are usable (provided a 9v battery box at least) and fast.

In the next future I will post some pictures

I was wondering how the original 12V motors compared to the otherwise identical 4.5V motors for speed?

[naboo]

From my memory I would say about twice as fast, maybe a little more, but it's without any scientific proof.

[monai]

the 12v motor use a different gear reduction as you can see if you open it, the different velocity is easily computable by a simple teeth count

theese motors were among the strongest Lego ever made, see

Wow. I love the 12V motors, although I think the results reflect the amount of grip available, which of course is increased by the added weight. The old 12V trains were built pretty heavy, and the last 4.5V one had those massive batteries on top together with the low gearing which made it unstoppable!

The old plastic rails also had traction ridges on them, which greatly helps. But I think the 4.5 and 12 v trains were designed to climb up to 1 brick in 16 studs, whereas the 9v motors were more like 1 plate in the same distance. The weight on the drivers is a big factor. With sufficient weight, the PF XL motors cannot be beat for pulling power (they will destroy gears if you let them, and axles if you hide the gears). The EN doesn't have much weight on the drivers.

[Heppeng]

It has enough though, I pull a heavy 4 coach train with it, but that has been enough to break one gear already!

This is a 4.5v train, using a PF IR controller in between the 4.5v standard battery box and the 4.5v motor.

Granted it doesn't use technic axles, I simple designed the engine around using the 4 wheel points and used large driving wheels.

I think it runs (and looks) okay..?
