Northern Line passengers starting their journey between Tooting Bec and Clapham North are to get localised travel advice on avoiding congestion.
Transport for London says this section of the line “is exceptionally busy between 08.30 and 09.00” which means passengers often have to wait to board a train.
From Monday it will advise passengers how small changes to their journey, for example starting slightly earlier or later, may allow them to avoid delays and complete their journey in less time.
Passengers will also be given information about alternative travel options including walking and cycling travel times.
TfL Is trialling the scheme on the Northern Line ahead of a wider roll-out next year.
Gareth Powell, London Underground’s Director of Strategy and Service Development, said: “During the 2012 Games many of our passengers made small changes to their journeys which meant we were able to carry record numbers without the transport network feeling any busier.
“By making a small change to the time they travel our passengers’ journeys could be faster and more comfortable.”
