When Rotala
purchased Diamond Bus from the Go-Ahead Group in 2008,
the company was keen to invest in the fleet by
introducing a number of new vehicles. The majority of
these were brand-new Volvo B7RLE single-deck buses,
which were divided between the company's Redditch and
Tividale depots. To supplement these new purchases,
Rotala also acquired six nearly new MAN chassis fitted
with Plaxton Centro bodywork. These vehicles were later
joined by a small number of additional second-hand
examples, further increasing the fleet. In 2010, Diamond
Bus introduced a further 23 brand-new MAN single-deck
buses fitted with MCV Evolution bodywork. Unfortunately,
these vehicles proved to be unreliable and suffered from
a number of technical problems. Ongoing issues
surrounding warranty claims and reliability meant that
Rotala decided to dispose of the entire batch. In early
2012, all 23 vehicles were sold to an operator in New
Zealand, where they were subsequently exported and
entered service.

With the
purchase of the South Lancashire Transport business, now
trading as Diamond North West, a number of MAN-chassis
vehicles joined the Rotala fleet. In keeping with many
of the vehicles operated by South Lancashire Transport,
several carried registration numbers incorporating the
letters SLT, reflecting the company's initials. Since
joining the Rotala Group, a number of these vehicles
have been transferred between depots across the wider
Diamond Bus network. One such example is M555 SLT, which
was initially loaned to the Kidderminster depot to help
alleviate a shortage of vehicles. The bus has since
remained at Kidderminster, where it now operates
alongside the depot's existing fleet of MAN single-deck
vehicles.

Transport
for West Midlands received funding from Central
Government to help bus operators reduce vehicle
emissions across the region. Much of this funding has
been used to retrofit existing buses with exhaust
after-treatment systems, enabling them to meet the Euro
VI emissions standard. However, the long-term ambition
is for all buses operating in the West Midlands to
become zero-emission vehicles, powered either by
electricity or hydrogen. As a more cost-effective
alternative to purchasing new vehicles, several
operators, including Diamond Bus, have taken part in a
programme to convert existing diesel buses to
battery-electric operation. The conversions are being
carried out by electric vehicle specialists MAGTEC. Each
vehicle has its diesel engine and drivetrain removed and
replaced with a fully electric powertrain incorporating
200 kWh of battery storage. Diamond Bus selected five of
its MAN single-deck buses for conversion. The first of
the five entered service from the West Bromwich depot on
1 October 2021, demonstrating the potential for
extending the operational life of existing vehicles
while significantly reducing emissions. During November
2023, vehicles 30302 and 30804 were transferred
temporarily to Diamond South East ahead of the
introduction of electric vehicles into that fleet.
Vehicle 30804 returned to the West Midlands in April
2024, while 30302 remained with Diamond South East.
