2. Remember the 'rush hour' The London Underground is very busy during 'rush hour' with commuters moving around the city. You can expect the trains and stations to be overcrowded between 7.30AM and 9AM in the morning and between 5PM and 7PM in the evening.

On the London Underground (the Tube), rush hour—also known as "peak time"—typically occurs in two distinct blocks on weekdays: from 7:30 AM to 9:30 AM in the morning and from 4:30 PM to 7:00 PM in the evening. During these windows, trains and stations are at their most crowded as commuters move in and out of the city center. Travel during these times is also more expensive, as Transport for London (TfL) applies "peak fares" to Oyster and Contactless payments. Monday mornings and Friday evenings have historically been slightly less intense due to remote work trends, while Tuesday, Wednesday, and Thursday remain the most congested days. If you are traveling as a tourist with luggage, it is highly recommended to avoid these hours to ensure you can find space for your bags and a seat on the train. The "quietest" times to travel are generally between 10:00 AM and 4:00 PM, or anytime after 7:30 PM. On weekends, there is no official rush hour, but certain lines can become very busy around midday or during major sporting events and concerts at venues like Wembley or the O2 Arena.
