Hi
I have also done this trip. It is great and you will have a wonderful time.
I took just an ordinary wheeled case and there were no problems, And Yes the men in group are bound to help you if you should need it.
The train journey was during the afternoon and early evening when I went and gave me an insight into the Russian style of travel. There is so much to see and do - a different way of life. The underground stations are amazing too.
Have a great holiday - I know you will - and don't forget your camera.
Be happy,
Best wishes,
