Well, sorry to say, they aren't! One day, with another file model, maybe bump maps will be in the cards, but I doubt that is possible with an MSTS shapefile without killing MSTS Bin.
If you would like to try this effect, it is quite simple. (Well Almost!)
1) On a purely artistic sense, select the parts of your model you would like to have "bumps" with.
2) For each of those selected parts, place an exact copy in the same exact location, and scale it slightly larger. This is the tricky part because OR renders things differently than MSTS. So you will have to experiment with it.
3) Now for each part that you scaled up, change its properties so that it is translucent. Also make sure that the material is either loshine or hishine.
4) Create a copy of the texture that was used for the original non scaled parts and with that copy create an 8 bit alpha layer.
5) It now important to think about what you just did in 4)! Essentially you want what is below that bump layer to "peek through". You may you use pure black, or shades of gray, and if your paint program allows it, add a little noise.
When you have exported your model you will see a sheen, dependent on what is in the texture and its alpha layer (windows come to mind). It also gives a 3D effect to things like hatches, doors, without having to create extra polygons to define each of those.
Of course, yes it increases the size (more polygons) of your original model, but it is nothing that OR can't handle size wise. It is not as nice as having real bump maps, but it is the best that you can do for now, and you can have it now! The key is to select only large parts of your model, the smaller parts may be too subtle to notice. Though it is not always the case, small parts can be intricate, that is, they can have a lot of polygons, and we don't want to double the size of the model by bump mapping everything!
have fun,
