Talking T Gauge

I'm not sure what the chassis are molded in, but given how flexibile they are, I suspect they might not be easy to bond. As for double-ended pager motors, I'm pretty sure that's an impossibility, or very nearly so.

Rats, I hate to always be saying "no" all the time!

Maybe epoxy could be used as a bonding agent?

As I see it, perhaps the biggest obstacle to producing a T Scale locomotive is haulage capacity. The 4 car 103 set requires two motor coaches just to shift it, and even then it is only actually hauling one carriage. I would suspect you could get away with two carriages at the most in any consist behind a single loco.

That said, these are early days, and perhaps further enhancements will result in a powerful enough motor to achieve this.

The other problem is of course the weight of the carriages/wagons for hauling. They need to be heavy enough not to fly off the track at the first corner, however light enough to to pulled in the first place.

I can realistically see powered cars every 2-3 units. That would be about the limit I'd say for haulage capacity.

For trains of closed cars like coaches and boxcars, that would be easy, open cars may be a bit more difficult...

Yes, it'll be interesting to see when the add-on sets previewed in the lid of the four car set (part number 106091 for 4 x 103 and 2 x 102 cars) become available just how many of them are powered.

Has anyone seen the 9000 series units on the market yet?

I wonder what Eishindo is planning for freight operations? I can see these trains well suited for passenger operations, but unless the freight cars are long enough to hide a motor inside, a locomotive won't be able to pull very many cars. Maybe a 6 axle truck powered loco could pull more than 2-3 cars?

I'm thinking that powered freight cars are the way to go. With a hood width of just over 4mm, a hood unit is feasible, but barely. you would have to have a paper thin side over a body cutout like AZL's units.

You could vacuum-form a simple body using thin plastic sheet.

Etched brass sounds like a good option.

Vaccum forming hte shell with a thin etched brass side would be perfect.

I was also doing some doodling, and since the wheelbase of a standard truck is .75mm in either direction of the current trucks, replacing the sideframe alone should give the illusion of a longer wheelbase truck. For the size of it, and if you have even basic details on the truck, they would almost surely hide the fact the wheelbase is 1.5mm shorter than it should be.

What is the overall height of the mechanism?

Just looking at currently available micro motors and I'm wondering the dimensions (length) of the current motor?

Didel has 4mm pagers in 8mm, 11mm and 14mm lengths. 8mm may be good for a switcher...

Does that mean it could be feasible to change the original motor should you burn the original out? Or pehaps there is a better quality motor out there to use.
