"Two long steel beams bended in a curvature shape resembling a U-shape. The specific objects or 'model' is intended for use in the video game named 'Team Fortress 2', which was released on the 18th of October, 2007. The beams' position suggests the thought that the beams in question form the rail, used for the transportation of railroad vehicles.
I have few issues, track is nowhere near aligned (grid 4 should at least match in long axis) nor matches theme of either available skins for stock tracks. I appreciate the effort, but you need to change this (and hopefully angle the planks too).
I didnt try this piece ingame but generally the tracks, depending on the piece have always been like this when connecting to other pieces. Some of them place ok, for some, you need to toggle snap to grid off. Every piece is different, sometimes they just wont fit as is. Sometimes you need to change the angle and rotate it more in order to make a visually nice fit.
