Titles read: "An Overall Overhaul! - or the private life of a London 'Bus."
Opening shot shows general view of traffic in a busy London street (The Strand?). We then see a London bus being dismantled and given its annual overhaul. The complete process is shown, with the engine being cleaned and serviced, upholstery being pummelled, the body of the bus being painted, welding of different parts, etc. Good engineering shots. Then the whole bus is put back together. Bus is shown tilted at an angle, possible because the top load is on the bus but the bottom isn't.
