That Causeway Bay junction is interesting with the loop through the raised planters.

Any good ideas on appropriate power trucks for HO scale interurbans initially running of 2 rail, than latter coverting to OVHD wire power? I figure, get something running untill OVHD wire can be strung.

Herb,

Did I read someplace (I have searched but can't find it now) where I think you said you were converting to catenary and would use RC and the BPS to recharge your Battery (?)

I have just bought three Tatra T3 kits in "O" scale but I am building mine for On30. The prototype ran with a Pantograph and the kit comes with one.

For a look at a really good picture of the Tatra T3:

The Model:



Will you talk about building a Catenary system and how you will wire for the BPS?

As for the BPS my first thought would be no track current and pickup current (+) from the Catenary and ground to the track. Second thought is Battery only and a section of "hot track" such as at the "car barn" to charge the Battery.

My knowledge on this subject is very low at this point.

Thanks

Bill-

Unusual that something that modern has a full pan, --most all you see anymore on modern stuff is Flaviley -or the like- half pans.

Well, as to your question. I tore all the single suspension wire down over one terminal and half the main, and erected catenary. Not entirely happy with the looks. While my "eye" is quite happy with the series of short straight tangents of single suspension over a sharp curve, catenary looks entirely too "busy" in the same situation. Might try painting the wire to kill the bright bronze look. Don't know---

As for the Stanton charging through the track system--I installed that in an On2 1/2 Plymouth (Ex Joe Car Works I think) and was running it on just a loop of HO snap track.
Performance is fine, great concept, but I think that Neil is working on a later version.

My standard gauge locos that are R/C use the standard S-cab. One is powered by a two cell pack, the other has a single cell, and a voltage step up board (BPS from Neil) to raise the 3.7V to 12V for the motor--although for that particular loco 7-8V is plenty fast enough for switching--probably too fast. Both work well, and do all that I could possibly want them to do--but I do recharge via a small Deans type connector under the floor of each loco, since all my rail is one polarity, and ungapped.

Pantograph equipped locos and coaches run 12VDC conventional control, and will continue to do so for the foreseeable future.

Don't know about writing the cat up. Not all that proud of the result.

Herb

Thanks Herb for the reply.

For the Tatra T3 models, which were mailed to me today, I have made a test chassis I call "The Mule". It uses two NWSL-Stanton Drives, a dummy and a powered unit made for On30.

I will instal the Stanton S-CAB system and BPS on this chassis. To test it I am going to build a short section of track with powered overhead on my test loop. After I see how that works I can then decide how I will continue.

Hi Herb,

In looking for a place to buy Catenary sections I found some for HO. Do you think they would work for On30?

Thanks
