I've previously booked passenger assistance several times to help me change trains when travelling alone with baby in pram, big suitcase, changing bag and handbag. The staff have been kind and helpful, and so have the people at the end of the phones when I've made the booking.
I recently got through to a jobsworth though, who said that I can't book help as the baby isn't disabled. It doesn't make sense to me - I won't be able to change platforms on my own. I physically will not be able to get from one train to the next, especially in the limited time available between trains.
East Coast is not some budget company - the train ticket between London and Scotland costs about £120, and I believe our trains are the most expensive in Europe. At these silver service prices, why can't I book help? In the past I have been helped while disabled passengers have also been helped, so I don't think it's to do with staff availability.
I think I will have to travel by plane in future, which is a shame as I'd rather take the environmentally friendly option of going by train, but with the plane, I know I'll get the help I need.
BTW when I was pregnant and tried to book help with luggage with Scotrail, they refused on the basis that getting pregnant was my lifestyle choice. That attitude oesn't help much when you need to travel alone somewhere.....
