London Buses route 142

London Buses route 142 is a Transport for London contracted bus route in London and Hertfordshire, England. Running between Watford Junction station and Brent Cross bus station, it is operated by Metroline.

History
Route 142 was introduced by the London General Omnibus Company in March 1914.

The allocation was transferred to London Country Bus Services' Watford garage, and became part of London Country North West in 1986. It was included in the sale of the business to Luton & District in October 1990 and retained the contract shortly afterwards, ordering 15 new Leyland Olympians to operate the route. The route was retained again in 1995, making it the first route to be retained by its existing operator through two consecutive retenders.

When re-tendered, it was retained by Arriva The Shires with new contracts commencing on 5 January 2008 and 5 January 2013.

On 6 January 2018, the route passed to London Sovereign from their Edgware (BT) garage with existing Alexander Dennis Enviro400s.

On 7 January 2023, the route passed to Metroline from their Edgware (EW) garage temporarily using existing Alexander Dennis Enviro400s, with brand new Alexander Dennis Enviro400EVs introduced in April 2023 and Wright StreetDeck Electroliner BEVs introduced in June 2023.
