"JOURNEY TIMES": We've done the best we can to figure out your commute-time, but we have to warn you that they are only approximate times. Our approximation is based on average tube journeys between the given tube stations during peak hours. It does not take account of any delays or closures eg due to signalling failures or planned maintenance tasks.
We have done our best to be conservative in our estimates of your journey time, and if all goes well you should arrive a little early at your destination. But we simply cannot guarantee that it will take the exact time given.
If you are concerned, please check the TFL journey planner for a more accurate time based on your particular needs.
