The LGOC B-type is a model of double-decker bus that was introduced in London in 1910. It was both built and operated by the London General Omnibus Company (LGOC).
A total of 900 of the buses were used to move troops behind the lines during World War I. After initially serving without any modifications and in their red-and-white livery, they were painted khaki. It was soon found that the glass windows on the lower deck were prone to breakage, mostly from contact with the men’s rifles and packs. The glass was therefore removed and replaced by planks nailed to the sides of the vehicle. Others were converted to lorries or vans, with the bus bodies being placed in storage.
The B-Type could carry 24 fully equipped infantrymen and their kit. Some were converted into mobile pigeon lofts to house the pigeons used for communication along the front. They served until the end of the war when they were used to bring troops home.
