There is however a chance that the staff will say "nope" if you want them to move heavy/bulky items.As a fit and able man I have actually used passenger assist a few times myself, if I'm travelling with a few bulky/heavy items of luggage and don't want to carry them off the train and out to the taxi by myself. There's no requirement to be "registered disabled" (as previously mentioned) so the service can technically be booked by anyone.
