Context:Imigqa eyishumi nanye yeLondon Underground ingamakhilomitha angama-402 ubude, okwenza kube uhlelo lwesikhombisa olude kakhulu lomgwaqo ongaphansi komhlaba emhlabeni. Lezi zakhiwa inethiwekhi engaphansi komhlaba nemigqa ejulile. Imigqa yeCircle, District, Hammersmith & City, ne-Metropolitan yakha inethiwekhi engaphansi komhlaba, enemigudu yesitimela engaphansi nje komhlaba futhi enobukhulu obufanayo naleyo yemigqa emikhulu yaseBrithani, ehlangana endaweni eyisiyingi enamacala amabili azungeze indawo 1. Imigqa yeHammersmith & City neCircle ihlanganyela iziteshi futhi iningi lomzila wayo nomunye, kanye nemigqa yeMetropolitan ne-District. I-Bakerloo, Central, Jubilee, Northern, Piccadilly, Victoria kanye ne-Waterloo & City imigqa iyizitimela ezijulile, ezinezitimela ezincane ezihamba emhubheni emibili eyindilinga (izitimela) enobubanzi obungamamitha angu-3,56. Le migqa inokusetshenziswa okukhethekile kwamathrekhi amabili, ngaphandle kwegatsha lase-Uxbridge lomugqa wePiccadilly, elihlanganyela ithrekhi nomugqa wesiFunda phakathi kwe-Acton Town neHanger Lane Junction kanye nomugqa weMetropolitan phakathi kweRayners Lane ne-Uxbridge; kanye nomugqa weBakerloo, ohlanganyela ithrekhi neLondon Overground's Watford DC Line engxenyeni yayo engaphezulu komhlaba enyakatho yeQueen's Park.  Amaphesenti angamashumi amahlanu nanhlanu alesi simiso asebenza phezu komhlaba. Kunemigudu engaba amakhilomitha angu - 32 yokusika nokumboza kanye nemigudu engaba amakhilomitha angu - 93 (150). Iziteshi eziningi zangaphansi komhlaba eziphakathi nendawo eLondon emigwaqweni ejulile yomhubhe ziphakeme kunezintambo ezihambayo ukusiza ukwehlisa ijubane lapho ufika nokusheshisa lapho usuka. Ngokuvamile izitimela zihamba ngomzila ongakwesobunxele. Kwezinye izindawo, imigudu ingaphezulu komunye nomunye (ngokwesibonelo, umugqa ophakathi nendawo empumalanga yesiteshi saseSt Paul), noma imigudu esebenzayo ingakwesokudla (ngokwesibonelo emgqeni weVictoria phakathi kweWarren Street neKing's Cross St. Pancras, ukuvumela ukushintshana kwepulatifomu yomgudu neNorthern line e-Euston).  Imigqa igcwaliswa ngogesi ngohlelo lwe-DC olunemigqa emine: ujantshi oqondisayo phakathi kwezitimela ugcwaliswa amandla ku-210 V nojantshi ongaphandle kwezitimela ezisebenzayo ku- +420 V, okunikeza umehluko ongaba ngu-630 V. Ezingxenyeni zomugqa ezabiwe ngezitimela eziyinhloko, njenge-District line kusuka e-East Putney kuya eWimbledon naseGunnersbury kuya eRichmond, kanye nomugqa weBakerloo enyakatho yeQueen's Park, ujantshi ophakathi unamathiselwe kuzitimela ezisebenzayo.  Ijubane elijwayelekile ku-Underground lingamakhilomitha angu-33,0 ngehora. Ngaphandle kwemigudu yaseLondon emaphakathi, izitimela zemigqa eminingi zivame ukuhamba ngesivinini esingaphezu kwamakhilomitha angu-64 ngehora ezindaweni zasemaphethelweni namaphandleni. I-Metropolitan line ingafinyelela isivinini esingama-62 mph (100 km / h).
