This is a 3D model of a DR track segment! They have S49 rail profiles and K rail fasteners.

Here's a close-up of the rail fastener. It's classified as "K", and it was commonly used in Germany and many other European countries.

And here's the rail. It's an S49 profile, also commonly used in Germany and in other European countries.

It also has some other details, like accurate fishplates and bevelled sleeper

It isn't completely accurate tho, because I didn't have measurments of everything, but I tried to make it accurate as possible. Like @isambird's models, this was made in Roblox Studio. While Roblox Studio is very limited when it comes to certain things (especially with measurments and complex shapes), it's super easy to use.

All of the parts were made within Roblox Studio with basic shapes, even the rails!

Yes, I could add even more detail, but in an actual game it would cause a lot of lag.

Once again a reminder that I'm still relatively new to this forum, and I'm bad at formatting posts (and my English isn't perfect either, I'm Czech afterall). Let me know if you'd like some more posts about my 3D models, or even if you would want to see some "stud style" ones (the same style that @isambird uses).

Thank's for reading! :)
