1938 tube stock

The 1938 stock resulted from a batch of experimental trains called the ‘[[1935 prototype stock]]’ and was intended for use on the New Works Programme extension to High Barnet and Mill Hill East on the Northern line. The 1938 stock served the Bakerloo line, Northern line, Piccadilly line, East London (today a part of the London Overground network) and Central line, eventually being withdrawn on 19 May 1988.

The 1938 stock was the result of an experimental batch of trains called the [[1935 prototype stock]]. The [[1935 prototype stock]] was an experimental train design that was built by Metropolitan-Cammell and consisted of 12 two-carriage units which where marshalled together to make four six-carriage trains. Three of the two-carriage units where streamlined and similar to the 1923 batch of Standard stock, with the fourth set with a front design similar to the later 1938 stock. The marshalled trains where then tested on the Piccadilly line between 1937 and 1940, then absorbed into the 1938 fleet before being withdrawn between 1972 and 1976.

The resulting 1938 stock was intended for use on the New Works Programme extension on the Northern line to High Barnet and Mill Hill East resulting from the electrification of the London and North Eastern Railway (LNER) lines. The fleet consisted of 1,121 carriages and constructed by two companies, Metro-Cammell and the Birmingham Railway Carriage and Wagon, being made up of 644 driving motors, 206 non-driving motors and 271 trailers. However, an additional 167 carriages where needed and came from an additional 91 new carriages and 76 converted carriages. The 1938 stock served the Bakerloo, Northern, Piccadilly, East London (today a part of the London Overground network) and Central lines, eventually being withdrawn on 19 May 1988.

1938 stock

The 1938 stock operated on the London Underground until 1988, there was a total of 1,121 carriages constructed by two contractors, Metro-Cammell and the Birmingham Railway Carriage and Wagon, with an additional 167 carriages, 91 newly constructed and 76 conversions, subsequently joining the fleet. These operated on the Bakerloo line, Central line, Northern line and Piccadilly line during their long lives.

The numbering of the 1938 stock is:

Use on different lines

The 1938 stock was primarily intended for use on the Northern line and Bakerloo line, with an additional seven trains being used on the Piccadilly line. The stock was commissioned by the London Transport Passenger Board (LTPB) under the New Works Programme between 1935 and 1940.

The Northern line received the 1938 stock for use on its new extensions to High Barnet and Mill Hill East and was exclusively served by the 1938 and 1949 stock. However, the trains where showing their age by the late 1960s and the first withdrawals from the Northern line began in the early 1970s with the introduction of the 1972 stock. There where 21 carriages which were scrapped because of the damage they had sustained from a collision, the last 1938 stock in passenger service ran on 14 April 1978. The 1938 stock returned to the Northern line in 1986 when five complete seven-carriage refurbished trains were transferred from the Bakerloo line to boast stock numbers because of rising passenger numbers, these operated until 19 May 1988.

The Bakerloo line received 36 seven-carriage trains from the Northern line between 1971 and 1978. The line was operating the 1972 stock in addition with the 1938 stock in the mid 1970s, however, the 1972 stock was intended to be used on the new Jubilee line, after its opening the Bakerloo line was exclusively served by the 1938 stock until the stock began to be withdrawn in 1981, by 1984 there were 16 trains remaining which where withdrawn by 1984/1985. The trains on the Bakerloo line received a 'extra heavy overhaul' which kept them in service long after their intended withdrawal date, this made the Bakerloo line the last to be served exclusively by the 1938 stock. A three-carriage train was restored to its original appearance in 1984, sponsored by a West End theatre agency the train became known as the 'Starlight Express' and worked on the Bakerloo line until 1985 when increasing traffic needed some of the recently withdrawn 1938 stock to boast train numbers as a stop-gap.

The Piccadilly line had seven 1938 stock trains which operated with the 1959 stock for much of their lives in service, these were replaced by the 1973 stock and the 1959 stock was transferred to the Northern line to replace the 1938 stock.

The East London line, today a part of the London Overground network, also saw the 1938 stock, which replaced the older Q23 stock.

The Central line received a single 1938 trailer carriage which was inserted into a 1960 stock train during the mid 1980s, this was used along the Woodford to Hainault and Epping to Ongar sections of the line. An additional unit, number 10177 which latterly was shipped to Alderney, worked on the Epping to Ongar shuttle between November 1957 and June 1960.

When the 1959 stock was approaching its life expectancy, five trains that previously worked on the Bakerloo line received a further overhaul in the mid 1980s. These were transferred to the Northern line for a further two years of service before the last passenger service on 19 May 1988.

Nine carriage trains

There were plans to operate a nine-carriage train service on the Northern line, as a part of the London Transport Passenger Board (LTPB) New Works Programme, these carriages where numbered differently than other carriages with the first digit '1' being replaced with '9'.

The formation of the nine-carriage trains on the Northern line where as follows: DM + NDM + SNDM + T + NDM + T + SNDM + NDM + DM

When the Northern line and Bakerloo line extensions where scaled back, there was the need to order additional stock to balance the stocks, this led to the ordering of the dubbed 1949 stock, where the carriages were renumbered in the early 1950s. The driving motors, which had been altered for nine-carriage trains for the Northern line, had their number changed from beginning with a '9' back to a '1', the driving motors where numbered 10342 to 1033, 11324 - 11333 and the trailers 012389 - 012408. Furthermore twenty eight of the thirty non driving motors where renumbered with the exceptions of carriage numbers 92055 - 92058 and where rebuilt into Uncoupling Non-Driving Motor along with twenty Special Non-Driving Motors, there were twenty two carriages that were rebuilt into Uncoupling Non-Driving Motor and renumbered 30000 - 30021.

1949 stock

The 1938 stock proved successful, when additional rolling stock was needed in 1948, 91 additional identical carriages where constructed. The fleet consisted of 70 non-driving motors and 21 trailers, these became known as the 1949 stock and worked alongside the 1938 stock. They were numbered as the same as the 1938 stock, the non-driving motors where numbered 30022 - 30045, 31000 - 31045 and the trailers 012495 - 012515.

58 Trailers

Fifty eight Standard stock trailers which where originally constructed in 1927 where converted in 1938 to work with the 1938 stock, these carriages where renumbered 70513 - 70570. The first carriage to be withdrawn sustained significant damage in an accident in Watford in 1962, the last carriage was withdrawn in 1973.

Accidents

There was one significant accident involving the 1938 stock occurred at Moorgate on 28 February 1975, when a train crashed into the end wall of the station killing 43 people and the driver.

Preservation

There are some carriages which have been preserved and refurbished, including carriages form the first built unit, is currently at the London Transport Museum Acton depot. The preserved units have been restored to their original red liveries, one has an orange roof which was standard for the Bakerloo line, and another with a grey roof which was used on the other lines. The preserved units are occasionally used in films.

A drivers cabin has been preserved at the London Transport Museum in Covent Garden, however this was not included with the museums refurbishment, however a driving simulator was fitted and located next to the driving trailer.

Thee ex-London and North Eastern Railway (LNER) carriages from the 1938 stock have been converted for use as ballast motors, another was modified to be used as a personnel carrier and a trailer carriage being used as a stores vehicle at Ealing Common depot.

The 1938 stock is still in use today, on the Isle of White Island line, the low tunnel clearances on the line make it ideal for using older tube stocks. The fleet was extensively refurbished and turned into two-carriage sets and reclassified as Class 483. Transferred to the line in 1988 they replaced the Standard stock carriages that where operating on the line until that point. There are six remaining ex-London and North Eastern Railway (LNER) self-propelling carriages on units 6, 7, and 8.
