A bus driver accused of causing the death of a pensioner blames mechanical failure for the crash, a court heard.
Michael Gilbert, 52, denied causing death by dangerous driving at a brief hearing at Teesside Crown Court.
Grandmother and great-grandmother Eileen Brennan, 82, died following the crash, in Darlington on July 7.
Another pedestrian was seriously hurt in the incident, which ended with the bus hitting a bank.
Gilbert, from Middleton St George, near Darlington, also denied causing serious injury by dangerous driving.
Christopher Knox, defending, said his client "believes that there was a mechanical failure".
A four-day trial was listed for August 29 and the defendant was granted bail in the meantime.
