Probably needs some cleaning, but might be normal for an older model. It is probably a common PM commutator motor and it is arcing some -- the arcing is causing the ozone. Re-powering it with a modern can motor can also cure it of the ozone smell.

Do a google search for 'Trolley' -- this will get you close. Technically, trolley wiring (as in Brills or PCCs or LRVs) is rather different from what GG1s and the like (AEM7s, etc) run under, it is going to be hard to find anything in the way of *functional* overhead wiring. Lots of model plastic towers, but they are not strong enough to support copper wire under tension. Working model (overhead) trolley setups use brass trolley support poles and phosphor-bronze wire, with cast brass or bronze fittings. The sorts of 'steel' towers used by high-voltage electric locos (like GG1s) are different. You'll probably have to hand make them from brass or something. You can probably use the phosphor-bronze trolley wire, though. Getting a *working* pantograph will likely also be interesting as well.

Model Memories does PRR and New Haven Overhead. GG1 only ran on PRR from Harrisburg or DC to New York.

You obviously got a rare loco with a "prototypical smell" unit installed. Although a nice feature on some models, I'd *strongly* suggest not buying the companion stock car.

check the brushes

"Model catenary" would probably come closer to what he's looking for.

Functional catenary is made by Sommerfeldt, Viessman, Vollmer, and others. All should be readily available in the US.

Sommerfeldt, again, for starters.

Do a google search for "Sommerfeldt" or "Viesmann"

------------------------------------------------- I believe Model Memories as Pennsylvania Railroad type catenary towers. As for the ozone smell, I seem to remember smelling ozone when a real GG1 whizzed by.

Bill Bill's Railroad Empire N Scale Model Railroad:

Keep running the machine.... Help replace the ozone layer....

Model Yesteryears (IIRC) has the Pennsy type catenary. Sommerfeldt and Viessman have the most realistic operational catenary and the time put in is well worth the while....

I got the chemical tank car. Had a bad derailment with it and the car sank through the foam scenery that I do. Big mess all around!

-- Why isn't there an Ozone Hole at the NORTH Pole?
