Type B Bus is an omnibus (bus) created in the UK in the early twentieth century to provide passenger transportation. The bus could carry up to 34 passengers exclusively on seating on two levels since they were not allowed to be transported in a standing position. In total, about 2,500 buses were produced and used on many specially designed inland routes. The advent of omnibuses created signiﬁcant competition for ancient transport, which consisted of horse-drawn carriages (cabs) and soon omnibuses completely pushed them out of the streets of London. Since the outbreak of World War I, a large number of these vehicles have been requisitioned to the army to accelerate the transfer of troops from the rear to the immediate war zones.
