The Pennsylvaniasarus (PRR T1)

This is an old project which I recently realized I neglected to post here.

This is my bolt for bolt replica of a PRR T1, recreated on behalf of the T1 Trust, a non-profit seeking to build a new T1 class locomotive to resurrect the lost class. The Trust provided me with all the surviving technical drawings, allowing for a truly perfect replica of that wonderful design. If you’re into this sort of thing, check them out here.

You can find additional renders, an animated flyby and breakdowns on my artstation here.


Fully rigged, animator friendly and 100% accurate. Everything is there, and everything works. From the Franklin B2 valve gear to the finest points of the suspension, which you can see demonstrated in the animated Artstation reel.

Thanks to the T1 Trust, Think Tank Training Center and the West Coast Historical Society for their respective generosity on behalf of me and my silly project.


I remember this, I downloaded all the old renders into my Great blender Renders folder that I keep for inspiration. The whole thing seems to have resolved itself wonderfully, it looks fantastic in a lit environment.


Thanks man.

Not really happy with the materials though, and porting to maya because blender’s vray port is crap didn’t make life easy. By the end of it i was just happy with any marginally good result, so long as i had a result.

Came out alright, all things considered.

You’re #featured! :+1:


Mighty kind.

Holy Shit! And I said that out loud prior to reading FXR’s comment.
What’s the stats of this project? Polys, texture memory etc.

34 millionish depending on subdivision level, approximately 6 gb of textures (though not all are used so who knows) and generally big and bad enough to make maya cry.

Though frankly that seems to be it’s thing.

Using maya was so awful i have an entire folder dedicated to archiving the most extraordinarily unreasonable crashes I’ve ever seen. It is not a small folder.


Holy crap! That thing looks like it would be unstoppable once it gets up some speed.
Awesome work, Steve!

I’ve made a train model, I know what a pain they are. Hats off to you sir!
Gorgeous renders.

I featured you on BlenderNation, have a great weekend!

I’m glad I looked at your train model, it has blown my mind like nothing I’ve ever seen. I used to use model trains, go to shows, ect. Seeing this done so well is truly amazing, I honestly believe that this may be one of if not the best scene ever posted here on Blender Artists. I looked at your post over at Art Station and saw just how much care was put into this and I wish there was a better way for me to share with you how well done this. I’ve seen some pretty good things in the time I’ve been here, but I don’t think any of them will trump your model of the PRR T1.

Meh, this is jaw-dropping! Kudos! How long did it take?

Eight months to model/texture, and about a year to render in maya.

I wish I was joking.

Looks great, Steve. I especially like the animation. If not for the looping, I could believe it was real, and I guess that says everything.

You should make the Allegheny 2-6-6-6

Very nice…
