Visitors to London will be pleased to hear that Transport for London will launch a night time tube service starting the early hours of 12 September. Thereafter, there will be a round-the-clock service on Fridays and Saturdays on Jubilee, Victoria, and most of the Central, Northern and Piccadilly lines.  Fares on the Night Tube are off-peak. Day and travelcards are valid on the day of issue (using the date printed on the card), and for journeys starting before 04:30 the following day. For example, if you buy a Day Travelcard at 11:00 on Friday, you can use it until 04:29 on the following Saturday. Daily capping on Oyster cards and contactless payment cards also applies.
