I'm currently creating the wagon to complement my interurban route called southern corridor. viewtopic.php?f=7&t=20428
I intend to have this trolley serve as the local streetcar for the route. only running in the towns, and not traveling on interurban lines due to voltage differences with i don't think the game can simulate.
I plan to work on this project over the summer in small portions, and will have to face a number of difference challenges through out its production. i plan to upload it here, and on my site when completed, and functional.

These are all the images of the streetcar production as of 5/19/2019 (10 am central)
Early Body
Body, roof, door , and interior, and lower body details completed.

Interior view.
Test export model in game.
Current things i have to do.
1. remodel some parts to a lower poly due to performance problems. the wheels are too high poly.
2. relearn how to make LOD for train sim.
3. add electrical, and other equipment such as the trolley pole, motor control box, and handbrake along with coupling hook.
4. maybe add tertiary elements such as hang lamps, bags, and stuff. no intention of having human models as of yet.
5. UV unwrap all the elements, and began the texture painting process in substance painter.
6. after that, and other test visual test. programming of the model will began.
I know how to make basic roiling stock up to 2 bogies, but i'm very confused about actually building an engine for a wagon, and turning it into a locomotive. The most i was able to manage was the creation of a simple electric engine, with a working handbrake, but i do not know how to create actual brake sub system.
my last rolling stock creation experience was here: viewtopic.php?f=9&t=20715
It's possible that for the time period these type of trolleys only had handbrakes.
sounds: gonna have to cross that bridge when i come to it, and i'm not competent with the sound system, and barley understand its workings.
Animation: for now i wish to keep it simple, but i would prefer to attempt a basic trolley pole animation, but it can be static like the trams made by Richard Scott.
My last animation experience is here: viewtopic.php?f=17&t=20417
Finally i'll need to research more about this trolley type when i start creating the engine. for now i only have a rough observation that these streetcars could really only run a speed of at least maybe 20-30 Mph or lesser. i'm also going to have to learn the horse power of traction motors of the time. this wagon only feature one traction motor on one axle.
Well i thank you for taking the time to read through my production page. it's you have any questions, or tips in making content. I'll be glad to answer them, and will also find your tips invaluable in my production journey. However my birthday coming up so i'll have to lessen production for the rest of the month.
Fixed the title from 18th to 19th century Thanks mindenjohn
