This Bus has a Powerful Engine

Apparently if you start a title with the word 'This' it lures people into watching it so I thought I'd try it 🤷‍♂️
Anyway here is a Cummins 6 Cylinder Optare Solo SR climbing Slack Hill. Although the bus has plenty of power sometimes the gearbox can't keep up with the engine, the gearboxes response generally slows the bus down, but 99% of the time this is by far one of the (joint) most powerful buses I've driven. Seen here climbing Slack Hill.
