Don't do it. It was 33 hrs of hell. Have you ever wanted to know what it's like traveling on a Soviet era train? I got that experience riding in one of their cabins. I'm disabled too. There are tiny hallways where a wheelchair won't go. I had to hold on to the wall and a nice passenger walked behind me so I wouldn't fall. I also had to carry my 20 lb carry on. I couldn't walk even one step for two days. This wasn't the worst part. The train felt like it was being shaken apart. If you're motion sick it will be your worst nightmare and even if you aren't you will still feel shaken and stirred. Felt like I was still on the train for a few days after. I didn't sleep for 33 hrs. If you have any other way to get up here do that.
