Pensioners who were stranded for over an hour in the hot sun when a bus did not arrive have criticised operators Trentbarton.
They have now complained to the company after a delay on the se7ens route, but bus company bosses say the service is operating at 99.5 per cent efficiency.
The delay happened on Friday afternoon as temperatures soared to 28C in the Belper area on what was the hottest September 30 for more than 100 years in the UK.
Sylvia White, 71, from Holbrook, said: “We were waiting for the 2pm, but nothing arrived at all. Nobody came round from the garage.
“There was a lot of old people at the bus stop – one lady was epileptic and looked poorly. “I felt shattered when I got in, but there were people in their 80s who regularly use it. They will be getting a lot of complaints.”
Sylvia says she uses the 7.1 and 7.2 buses travelling either to Derby or Belper most days.
She claimed: “Most weeks it’s late because something’s happened. “They have the very best drivers but the buses are not new – they’re just repainted. We didn’t have this trouble on the old red ones.”
Alex Hornby, commercial director of Trentbarton, apologised for the delay but denied there was a recurring problem with the se7ens.
He said: “We’re sorry for the cancellation of a trip on the se7ens route this past week due to a vehicle fault which has since been rectified. “Obviously, there was a short delay whilst we attended to this particular issue before the service was fully restored. “We have faced no clear trend of problems on the se7ens with an over 99.5 per cent of total mileage operated on this route across the past six months.”
