Moving while pregnant

So I'm planning on moving to be closer to my mother so she can help me with my first child. I'll be moving by train alone, well with my service dog. I am pretty nervous and will miss my fiance terribly but he will be meeting us there eventually and hopefully before the baby is born, but he has surgery that he needs done before he can go with us. Why train? I have a fear of planes and the stress would not be good for the baby so I'd rather take the 2.5 day train ride over the 8 hour plane ride. Silly I know but all accommodations have been made to make this trip comfortable for my and my service dog.
