The route was introduced in 2016 as a replacement for route 141. It operated between the same terminii, Birmingham and
Merry Hill Shopping Centre, but runs as an express service with a frequency of one bus every 20 minutes. National Express stated that this was in response to customer feedback.[1] In 2018, one bus per hour was extended to Gornal Wood. The extended service was funded by
Transport for West Midlands.[2] In November 2022, it was announced that the extension to Gornal Wood could be withdrawn.[3][4] In late December 2022 it was confirmed that the X10 will continue to serve Gornal Wood but to a revised timetable.
