Paddington was extended again from 1930 to 1934. Platforms 2 to 11 were extended past the Bishop's Road bridge and a new parcel depot was built. Suburban services, which had never been considered important at Paddington, were increased as new housing estates in the Home Counties started being built. Bishop's Road station was rebuilt, giving an extra four platforms to Paddington (Nos. 13–16) and providing a new ticket office and entrance for suburban services next to the bridge. A public address system was introduced in 1936. By this time, around 22,000 parcels a day were being forwarded from Paddington, with the Royal Mail service processing around 4,500 mailbags and 2,400 parcel bags every day.
