Cock, C.M.
Successor to Raworth on the Southern Railway and Chief Electrical
Engineer of the Railway Executive.
Bonavia (British Rail: the first
25 years) noted that in May 1948 the BTC had arranged for a joint
British Railways and London Transport Committee, chaired by C.M. Cock, to
be set up to consider the system (or systems) of electrification to be adopted
in future projects, reviewing in particular the conclusions of the Pringle
Committee of 1927 which had proposed direct current at either 1,500 volts
with overhead collection for general use, and 750 volts third rail for certain
areas. The Cock Committee broadly confirmed this, but did not rule out the
possibility of using, as it put it, 'single-phase alternating current at
50 cycles or a lower frequency for secondary lines with light traffic, subject
to the proviso that it is not prejudicial to operation on adjacent lines
equipped with a standard system'. This opened the way for the decision taken
in 1951 to use the short Lancaster-Morecambe-Heysham line, which the Midland
Railway had electrified many years ago on the 6,600 volts 25-cycle single-phase
system, as a testing-ground for electrification at the industrial frequency
of 50 cycles (Hz), which seemed to offer important advantages, especially
in cutting down the cost of the distribution network. This system had already
been tried in Hungary as early as 1934 and the SNCF was proceeding to install
it on an important main line in Eastern France. This probably implies that
Rogers gives excessive credence to Riddles involvement in the Lancaster/Morecambe
project.

Emerson, Alexander Hockley
President (1969-70) Institution Locomotive Engineers (Journal,
1969, 59, 5 (portrait facing page). Born at North House, New England,
Peterborough adjacent to the coaling plant. received early training as
Mechanical/ Electrical Premium Apprentice under Sir Nigel Gresley at
Peterborough, Doncaster, South Gosforth (Newcastle) and Grimsby (Immingham)
from 1926 to 1934. In 1935 served as a Senior Draughtsman in the office of
the Chief Electrical Engineer, LNER, King's Cross, first concerned with Outdoor
Machinery, New Works Projects and then on Railway Electrification Schemes.
This included the early reports and technical work for the Liverpool
Street/Shenfield, Manchester/Sheffield/Wath, South Tyneside Electrification
Schemes which were initiated before WW2. During WW2 was seconded to Dukinfield
factory near Manchester as Assistant Resident Engineer (Electrical Engineering)
and returned to the LNER in late 1943 to pursue Electrification Schemes and
other post-war projects which were being planned in the Chief Electrical
Engineer's office. In February 1950 appointed Resident Electrical Engineer,
Manchester, to take charge of the outside erection and supervision of the
building of the Manchester/Sheffield/Wath Electrification and the locomotives
for it. This was followed by his appointment as Electric Traction Engineer,
Manchester, on 17th September 1951, where he remained to complete the
electrification of these lines and set up the maintenance organisation for
this project, and integrated it with the organisations for the Manchester/Bury
and the MSJ&A lines on the London Midland Region. In July 1955 Emerson
moved to Derby to become associated with the main line electrification between
Euston, Manchester and Liverpool, first as Assistant Electrical Engineer
(Modernisation) and following as Electrical Engineer for the London Midland
Region. In 1963 he was appointed Assistant Chief Mechanical & Electrical
Engineer, LM Region, Derby, and in January 1966 Chief Mechanical & Electrical
Engineer, Euston and Derby, succeeding A.E. Robson, the immediate Past-President,
when the latter moved to the British Railways Workshops. See Maintentance

Raworth, Alfred
Alfred Raworth was the son of John Smith Raworth, consulting electrical
engineer to the British Electric Traction Company and one of the pioneers
of Britain's electrical industry. He held a large number of patents relating
to the generation, distribution and utilization of electricity. Alfred Raworth
was educated at St. Aubyn's, Lowestoft and Dulwich College, and then served
apprenticeships with Browett, Lindley & Co. Ltd. of Patricroft, Manchester,
and the Brush Electrical Engineering Co., Loughborough. From 1903 to 1912
he acted as assistant to his father and showed himself to have a fertile
engineering brain, designing new equipment such as regenerative braking circuits
and stepless traction controllers. In March 1912 he was appointed chief assistant
to Herbert Jones, chief electrical engineer of the London & South Western
Railway and he helped to prepare a report to the directors on the electrification
of a substantial section of the company's suburban system.
Raworth, however, who had been intimately concerned with the project was no longer around to witness the opening as he had joined the Royal Naval Air Service and was commissioned as Lieutenant, RNVR. In February 1918, on Walker's recommendation, the SECR obtained his release from the RNAS and appointed him its electrical engineer.
The SECR had obtained powers for electrification as early as 1903, at the same time as the GER, but like the latter company made no attempt to implement any plans. Lack of capital and also doubts that any major economies could, in fact, be made by electrification saw the idea in abeyance until 1912 when a report was commissioned from the Newcastle firm of consulting electrical engineers, Merz & McLellan. Their report was issued the following year and recommended a system of 1,500V dc using either overhead or third rail collection. In the meantime the neighbouring LBSCR had begun overhead electrification on an ac system of 6,600V at 25 Hertz and the view was held by some on the SECR that the Brighton system should be adopted. All of these ideas were shelved with the onset of WW1.but following the appointment of Raworth the whole field was opened up again and after the Armistice he was sent to the USA for three months to study the various electric railways and equipment in operation.
His proposals were contained in a report to the SECR dated October 1919. Three stages were contemplated: firstly 94 route miles of London inner-suburban lines to be operated by EMUs, secondly, main line extensions to Gillingham, Tonbridge, Oxted, Redhill and Dorking also using EMUs and finally the replacement of freight and main line steam-hauled trains by the use of electric locomotives in the electrified zone. The final total was envisaged as 241 route miles.
Raworth's distribution scheme, however, was novel and most ingenious. A company-owned generating station was proposed at Angerstein Wharf , Charlton and power would be supplied at 3,000V dc. Four rails would be used, as on the London underground lines, but on Raworth's system the central conductor rail would be fed at -1,500V dc and the side conductor rail at +1,500V dc, the return being through the running rails. This method of feeding current (known as 3-wire distribution) used much lighter feeder cables and thus saved on copper. With this system only one substation would be needed for the inner-suburban electrification (instead of 26 for an equivalent 600V LSWR arrangement) and only four would have been required for the complete project. Stray leakage currents to earth, which were a potential problem with telecommunications and scientific instruments (such as those at Greenwich observatory), were thought to be negligible because the opposite polarities of the conductor rails would cause them to cancel out. The LYR 1,200V dc third rail Manchester-Bury line was investigated and the permanent way staff interviewed. It was found that with side contact and protected rails the high voltage was neither a danger nor caused extra maintenance problems. Each EMU set was to have two 1,500V motors, one collecting from the positive conductor and the other from the negative.
However ingenious Raworth's plan and however much cheaper it would have been there were already many other influences around to thwart any 'best option' solution. In March 1920, the Ministry of Transport appointed an Electrification of Raliways Advisory Committee under the chairmanship of Alexander Kennedy. Its brief vas to study the existing electrified railways nd schemes in hand and to recommend a uni ormity of approach. There were also the future railway amalgamations on the horizon and following the passing of the Railways Act rf 19th August 1921, negotiations were commenced between the various constituent companies. An Electricity Act of 1919 had made compulsory approval by the Electricity Commissioners of any scheme for a generating tation. There was a great body of opinion in and out of the electrical industry that a national grid was necessary and that electricity users hould purchase their energy requirements from suppliers rather than building their own specialist power stations.
The Angerstein Wharf project was rejected in 1922 and with amalgamation approaching, the LSWR became hostile to the proposed SECR system; the prospect of three completely different systems on the future Southern Railway filled the provisional management committee with a good deal of unease. The BoT Electrification Committee had come down in favour of 750V or 1,500V dc for all future lectrification schemes (either third-rail or overhead). Once the Southern Railway was in being, one of the first decisions made by the board was to electrify the SECR suburban lines on the LSWR system, ie 600V dc third rail.
Raworth, no doubt, learned a great lesson from these events that engineering perfection may have to give way to pragmatism, compromise and the acceptance of managerial decisions based on non-technical parameters, he soon set about making the best of things under the new company he became once again deputy of Herbert Jones who had been made chief electrical engineer of the Southern. After completion of the electrification of the ex SECR suburban lines in 1925, Raworth's new title became 'electrical engineer for new vorks' and for the rest of his career he organized and guided the extending web of the Southern's electrified lines as laid down by the overall policy of the general manager and the board of directors

Weir, William Douglas
Born on 12 May 1877 in Glasgow, the eldest of three children of James
Weir (18431920) who with his brother George had in 1873 founded a marine
engineering and maintenance company. James patented several inventions (including
the Weir feed-pump), which in 1886 the brothers began to manufacture in a
machine shop and smithy at Cathcart near Glasgow. These premises were developed
into the Holm Foundry, and the business of G. and J. Weir was formed into
a limited liability company in 1895. William Douglas was educated at Allan
Glen's School and at Glasgow High School. At sixteen he entered an apprenticeship
in the family business. He was successively director (1898), managing director
(190215), and chairman (191053) of G. and J. Weir. He was made
Viscount Weir in 1938 (presumably in association with the Glasgow Exhibition
of that year). He was an administrator in both World Wars and chaired the
Weir Committee on railway electrification. He died on 2 July 1959, at Eastwood
Park, Giffnock in greater Glasgow. The bare bones of this entry came from
an ODNB biography by Richard Davenport-Hines,
who does not mention either railway electrification or the Glasgow Exhibition..
