I imagine the Lime was pulling behind another bus which was already in (hence its position at the stop). The driver behind has misjudged braking distance (likely to have assumed the bus was going to pull all the way into the stop) and managed to crash straight into the back because the bus stopped.
It has caused quite a lot of disruption... Traffic in both directions is being forced to use one lane (where the van is on the photo). Looked quite strange seeing a Silver Arrows Merc overtake so hastily on that lane which I observed.
