According to the Local Democracy Reporting Service the feasibility designs would also set out how charging infrastructure and other upgrades for zero-emission vehicles could be installed.

Olive Grove in Sheffield, currently used by First Bus, has been described as “critical” to the first phase of franchising because of its size and central location.

Once the designs are complete, SYMCA will decide whether individual depots should be refurbished, partially rebuilt or, if necessary, redeveloped entirely.

Any works are expected to be carried out by the current operators under the combined authority’s oversight.

The franchising model means SYMCA will set routes, timetables and fares across the region with bus services brought under one brand.

The move will cost SYMCA £25m to transition to the new franchising system over the next three years.

Under the proposal bus companies will no longer be able to run the services they choose but will have to bid for specific contracts set by SYMCA.
