A city bus with 20 passengers on board had to be evacuated after the vehicle caught on fire.
Appliances from Carrow and Sprowston were called to the vehicle fire on Thorpe Road at about 9.10am on Saturday morning.
They used hose reel jets and compressed air foam systems to extinguish the fire at the bus's back end.
Shaun Tooth, interim managing director for Konnectbus, said: "The good news is that everyone was okay and no injuries were reported.
"We think there were around 20 passengers but the driver did a good job of evacuating the bus when the alarm was raised.
"We cooperated with police, fire and ambulance crews on site
"We will be investigating the cause of the fire, but we do not know at this stage. We will also be reporting it to the DVSA."
The Konnectbus remains on the road but is in a city-bound bus lane, near to the junction with Cotman Road, so hasn't caused much disruption to traffic.
The incident was under control by about 9.40am.
