I had read you post on March 18,2005 and noticed that you have been to the Holborn Tube station. I would like ro ask some questions. I will be travelling from Heathrow to central london and get off at Holborn with a piece lof luggage and one carry on. I do no know about the stair situation on the Holborn station. Is is possible to carry the luggage up the stairs?How many sets of stair would I go through before I reach the street level?If I carry the luggage on the tube, would it be too much inconvenient to other passangers? Please help me with some information and suggestion. Thank you.
