How bad might my car be damaged?

So I hit some bad railroad tracks super early this morning in the fog. Obviously, I know my car is damaged.

My 2 front tires are blown to heck. I may even need rims and I know I'll need an alignment. I am not worried about that. It won't be bad to replace tires and stuff. I was about to replace them anyway. So if it's JUST tires and an alignment I will be glad. But I am very afraid it could have damaged something underneath my car. I didn't have any lights on my dash or anything (no check engine light or anything like that), my car was not smoking, I didn't smell anything except for rubber from the tires and I didn't see anything leaking.

What COULD have happened by hitting tracks like that? I am very upset by this to say the least. I had it towed to a shop and they are going to check everything underneath tomorrow and fix my tires.

I was just curious if anyone had any idea on any other things I may need to be prepared for and what could be damaged from this type of issue so I can estimate costs.
