Find a locomotive that works, take note of it and check the settings for the textures by opening it up in Content Manager. Compare that setup to the one that's giving you a problem and make changes accordingly if you can.

My hunch it has something to do with an alpha-mask, but I'm not a content-creator so use that as a possibility, but not necessarily the answer.
