Southend Fleetline 377, GHJ377L, seen in the aftermath of a collision with one of the Southend Leopards which rolled down the station approach, allowing it to cross the High Street and into 377. Despite being a busy Saturday, there was no traffic passing as the Leopard rolled across the road.

The impact pushed the Fleetline onto the pavement, causing it to hit the base of a lamp post which then toppled backwards and the top of the lamp post went through the window of the building behind.
