						King Edward IV leading No 6005 King George II and No 6001 King Edward VII
						leading No 6014 King Henry VII, carry out bridge tests on the newly
						quadrupelled track between Olton and Lapworth by travelling neck and neck at
						62mph along the route. These locomotives were the heaviest owned by the
						company, each locomotive weighting approximately 136 tons (with a loaded
						tender} and having a maximum axle weight of 22 tons 10cwt. When the government
						introduced the Development (Loan Guarantees and Grant Act of 1929s to releive
						unemployment during the drepression, the Great Western Railway embarked on a
						comprehensive programme of infrastructure works including the completion of the
						quadrupelling of the main line south of Birmingham.  Previous work had provided five miles of quadrupelled track
						from Moor Street as far Olton. The new work would extend this four track
						section a further seven miles to just south of Lapworth station. The work
						started in 1930 and would take three years to complete. It involved the
						construction of 33 bridges, the rebuilding of two stations (Olton and Solihull)
						and the extensive remodelling of a further three stations. Existing track was
						relayed and realigned to ensure maximum speed (with no curves having a radius
						smaller than one mile, except one curve on the relief line at Knowle and
						another at Olton where the radius was 4000 foot). High speed junctions with
						switched diamond crossings were laid at Lapworth, Knowle and Solihull. The
						permanent way was 95lb/yd bull-head rail in 60 foot lengths resting on 46lb
						cast iron chairs fixed to creosoted Oregon pine sleepers. Track-circuit
						indication was provided throughout and new signal boxes were built at Olton and
						Solihull. The main contractor was Cleveland Bridge and Engineering Co Ltd. Robert Ferris  back
