It's your first time in London. You have heard and read much about the place but what you really want is to experience it. The transportation used in London is what interest you the most. You have seen various transportation vehicles from varying generations. So you visited a museum of transportation vehicles. It's like you stepped back in time. Vehicles of different designs and features lined up. Taking up the opportunity, you poked your head in every vehicle you find and look at it carefully. Then questions came up in your head. You looked for the staffs in the museum but no one is in the room. You decided to check the front desk but the door locked itself. So you traveled around the still vehicles to escape the museum.
