Talking T Gauge

More can be found at http://www.nidec-copal-usa.com They have a 4mm stepping motor as well as standard and brushless motors. Most appear to have contacts.

Check also with the micro R/C world (Zip-Zaps, Microsizers, etc) for replacement motors. I guess some of those are supposed to be faster than others?

Interesting sites, both of them.

I've got a few drive ideas on how to power a switcher as well as a steam loco. Biggest problem I can see, as stated before, would be torque. A T Gauge hood diesel would need to have a 3mm motor or a wider body and narrower walkways to be powered, and I'm not sure if the 3mm motor would be up to the task.

I seem to recall Tim Buering had some micro-sized motors he said ran for a long long time in a vice test, but I can't remember how big they were...

I just found this link on Trainboard http://www.goldmine-elec-products.com/prodinfo.asp?number=G13566&variation=&aitem=1&mitem=1 and it's for a 4mm motor.

According to the poster, one of these was connected to 12 Volts and running 24/7 for over a month and didn't even get hot. That's a fair cry from 40 hours Wink

Price is pretty reasonable too

I was looking for that topic on 40 hour life of those motors, and could not find it again, but the thing I did realize while looking, is they are running a small propeller at fast speed, so maybe that is the cause of the short lifespan?

Anyways, I am thinking about trying Tim's favorite motor out, and use my 10V Marklin power supply on it. If the motor is the same size, it should not be hard to retrofit at all.

Pager motors are designed for brief, intermittent use, aren't they?

Exactly. That's why I think seeing if these 9V motors work w/T Gauge equipment will be a good start. Higher voltage means lower speeds at 4.5V (theoretically)

You know, we lived with stretched Life-Like F7s in N, as well as other locos on the wrong wheelbase. I've got no problem with stretching or compressing (within reason) to get a reasonable overall impression. Plus given the power setup in T, there's no rule about making a prototypical looking loco with the power hidden in an attached coach.

Further to the discussion earlier regarding freight trains and needing powered cars spread along the train.

It occurs to me that all the wheels so far available are not very free-rolling due to the current collection on them. I tried to order the bogies for the yet to be released SAHA trailer cars - these will not have current pick-ups as they have no motor or lights. The bogies are listed on their spare-parts list, but they told me they are not ready yet.

Now, if there were to be future bogies / trucks with pin-point bearings, I wonder what difference that would make to the haulage capacity of any future locomotive?

Given that Eishindo have now revealed that they shall release steam locomotives, one must wonder what they are planning to put behind them. Are powered passenger or freight cars to be available, or frictionless (?) bearing rolling stock instead?

Actually, you have to wonder if the locos will be motorised at all. Wink

The trucks that have no electrical pickup are actually fairly nicely free-rolling. But these are kind of rare--they're only on the end cars under the LED modules. Since they keep chaning their truck designs, they were available only for a brief period: first they used to have trucks with the electrical tabs cut off here, then they had the nice-rolling ones, then they squeezed in electrical pickup to improve the lighting. I wonder if we can obtain these at all--they have plastic pins that fit into the wheel ends, in place of the stamped metal pickup plates, which add considerable drag.
