I travel a lot on the train and always book mobility assistance. The quality of this does vary greatly from station to station but when it works well, it is fabulous. I usually just use a walking stick but am making my first solo train journey in a wheelchair next month. I have travelled on trains in my wheelchair a couple of times in the past but I have been with my Mum and step-father. I have to say I am quite anxious about this particularly as I will have to negotiate a suitcase as well. Although I would rather not have a case I am going to a wedding so it is unavoidable really. I am going to buy a suitcase on 4 wheels (I think that will be easier) and I just hope the assistance is up to scratch!
