I need to travel from south east London to Farnham in Surrey. I don't drive. In the past I have gone by train via Waterloo East and London Waterloo main. However, I am now in my eighties and walking has become very difficult. I can no longer manage the transition from Waterloo East to the main concourse at Waterloo main. It involves a steep ramp and then a long walk-through. I would be travelling alone. Does anybody have any suggestions, please?
