The route along which the 43 operates was designated as London's first Red Route bus priority scheme in 1992.[3] Later, in late 1999, the route became one of the first in London to be operated by low-floor double-deck buses, when new Plaxton President bodied Dennis Trident 2s were introduced.[4]
In 2021, the frequency of the service was reduced from 9 buses per hour to 7.5 during Monday-Friday peak times, and from 8 buses per hour to 7.5 during Monday-Saturday daytimes.[9]
Variants
In 1992 a peak hour route X43 was introduced to supplement route 43 in connection with the Red Route bus priority scheme introduced at the time. It used specially liveried Scania N113 double-deckers branded as Red Express. London Northern, the subsidiary of London Buses which had taken over operation of the route in 1989, stated that passenger numbers along the route increased by 8,700 in the year following its introduction.[3][10]
Route 43 is mentioned in the song Bros by North London alternative rock band Wolf Alice. A route 43 bus is shown at the very end of the music video for the song.[12]
