Tried to get into central London yesterday alone with dd in buggy. At two separate stations without lifts I asked for help and was told they couldn't because of health and safety or insurance. (And i have heard this several times before.) Given that only about 10 per cent of tube stations have lifts I think refusing to help in any way is lame and amounts to discrimination, albeit of a passive and unintentional kind. I know that sounds a bit hysterical but the practical outcome of this situation is that if your child needs to be in a buggy and if you don't have anyone with you to help you you cannot travel on the underground...
