For example, say I'm travelling on the last train of the day from London Paddington to Worcester Foregate Street. The train's late and it terminates at Worcester Shrub Hill. Say I've left my bike locked up at Foregate Street, so I really must return there. I'd walk it in about 12 minutes. But could I insist GWR get me there without walking, by providing a taxi, or is it considered a reasonable distance to walk? Taking it a bit further, say I'm travelling from Glasgow to Lancaster and then to Morecambe. I'm booked on the last train of the day from Lancaster to Morecambe but the train arrives late into Lancaster and I miss it. I could walk from Lancaster to Morecambe, it's possible, but it would take me about an hour and a quarter. Can you insist that a train operating company gets you to your actual destination station, if they can only get you to a station within walking distance of it? Who would decide what distance is "reasonable" to walk? Some people might have problems walking even short distances.
