For quick access and to avoid those endless bits of paper you can text or e-mail your itinerary to your mobile phone, including times of trains and the reference number of assistance booked on the railway.
Programme all assistance numbers into your mobile phone in case things don't go according to plan ie: late flight arrivals or missing a train, they will do their best to help you even at short notice.
A small bag that fastens around your waist is much more convenient for tickets, passport and cash and much less likely to get lost or stolen than a shoulder bag when you're juggling with other luggage and mobility aids.
Happy Travels.
