I would like to know what's the average train speed on the following lines. 1. Jubilee line 2. Victoria line 3. Central line 4. Bakerloo line 5. Northern line 6. Metropolitan line 7. Piccadilly line 8. Circle line 9. District line 10. Hammersmith & City line 11. Waterloo & City line 12. Overground - Richmond/Clapham Junction - Stratford 13.

London Underground train speeds vary across our network, from as slow as 15MPH, up to 60MPH. The speed of the trains can be impacted by a range of factors including the track infrastructure, the type of signalling system, the distance between stations, and the frequency of services in the timetable. For safety reasons, our Underground trains have a maximum speed of 60MPH.

We often run trains in central London at a slower speed, as this allows us to have more trains on the network moving more passengers overall. The faster a train is going, the more distance is required to speed up and slow down at stations. Because many of our stations are relatively close, running the trains slower means we need smaller stopping distances and can have more trains on the line.

Lines like the Metropolitan and Northern lines see the greatest variation in speeds, as once they get into the suburban areas, there is more distance between stations allowing them to get closer to 60MPH.

The table below shows the average speed on London Underground lines, Km/h.
 
Bakerloo 27.04
Central 37.29
Circle 24.31
District 29.44
Ham & City 27.65
Jubilee 40.32
Metropolitan 44.14
Northern 34.09
Piccadilly 32.65
Victoria 42.49
Waterloo & City 33.30
