The British Rail Class 25 diesel locomotives were originally known as British Railways Type 2. They were nicknamed Rats. 327 locomotives of this type were built between 1961 and 1967.
British Rail Class 26
The British Rail Class 26 diesel locomotives, originally known as BRCW Type 2, were built by the Birmingham Railway Carriage and Wagon Company (BRCW) at Smethwick in 1958-59. Forty seven examples were built, and the last were withdrawn from service in 1993.
British Rail Class 27
The British Rail Class 27 was a diesel locomotive built by the Birmingham Railway Carriage and Wagon Company (BRCW) during 1961 and 1962. They were a development of the earlier Class 26. Both were originally classified as BRCW Type 2. There were 69 locomotives in the class.
British Rail Class 28
The British Rail Class 28, originally known as Metropolitan-Vickers Type 2, diesel locomotives were built as part of the British Railways Modernisation Plan. The locomotives had a Co-Bo wheel arrangement. There was a 6-wheel bogie at one end a 4-wheel bogie at the other end. This wheel arrangement was unique in British Railways practice but not uncommon in some other countries, notably Japan. This affected their route availability, due to the different axle loading at each end of the loco, and made maintenance more complicated. The maximum tractive effort was unusually high for a Type 2 locomotive but, as there were five (not four) driving axles, the risk of wheelslip was minimal.
D5705 is preserved at the East Lancashire Railway.
British Rail Class 29
The British Rail Class 29 consisted of 20 diesel locomotives which were rebuilt from the North British Class 21. The original licence-built MAN engines of the Class 21s had proved unreliable, so in 1963 locomotive D6123 was sent to Paxman's Colchester works to receive a new Paxman Ventura V12 engine. A further 19 were re-engined in 1964-1965 at Polmadie Works, with other changes made at the same time. This included the fitting of four-character headcode displays in the nose ends. After rebuilding, they returned to service from Eastfield depot in Glasgow.
Although these offered more power and much improved reliability over the original Class 21s, they did not survive much longer, due to their small class size and the use of a non-standard high-speed diesel engine. D6108 was withdrawn in May 1969 and scrapped by McWilliams of Shettleston in 1971, while the other 19 were withdrawn between April and December 1971 and scrapped at BR's Glasgow Works in 1971-72. No Class 21 or Class 29 locomotives survive today.
Chess piece
In the board game chess, each player starts with 16 Chess pieces. The moves of the pieces are defined by tradition, and by the international chess federation, FIDE.
The bottom-right square of the board for each player must be white.
Pawn - A pawn can only move ahead, to the far end of the board. A pawn is placed in each square on the second row away from each player at the beginning of a game, right in front of all of their other pieces, so each player begins with eight pawns. Most times, a pawn can only move to one square, the square in front of it. But a pawn that has not moved yet in the game can move ahead two squares, or just one.
If an enemy piece is straight in front of a pawn, the pawn cannot capture that piece. Pawns have a special way to capture. A pawn can capture an enemy piece which is on the diagonal square to the left or right of the square in front of it. This is the only time a pawn can move to a square that is not straight in front of it.
If a pawn reaches the end of the board, it is removed and replaced by any other piece the player chooses, except a king or pawn.
If a pawn moves two squares on its first move, it may be taken (on the opponent's next move only) by an enemy pawn as if it had moved only one. This is called ""en passant"" (French for "in passing"). A pawn is worth 1 point.
Bishop - A bishop can move any number of squares "diagonally", meaning, if you pretend the bishop is in the middle of a big X, it can move to any square along the lines of the X. Because of this, a bishop will be on the same color of squares for the whole game. At the start, a bishop is placed on the third from the left and third from the right of the row of pieces closest to each player. A bishop is worth 3 points.
Knight - The knight is special because it is the only piece than can jump over other pieces. When a knight moves, first it goes two squares in one of the four ways a rook can move. Then the knight ends its move by going one square to the side. The knight is said to move in the shape of an L. See the picture "(picture is coming)". It "jumps over" the pieces on its way to its new square, and does not capture them, but the knight will capture an enemy piece if it lands on one. Knights are placed at the second and seventh squares on the rows closest to each player, between the rooks and the bishops. A knight is worth 3 points.
Rook - A rook can move any number of squares: left or right on the ranks, and up & down on the files. Rooks start at the far left and far right squares in the row closest to each player, next to the knights. A rook is worth 5 points.
Queen - The queen combines the moves of a bishop and a rook. The queen is placed next to the king "on a square of its own colour". Thus the two queens exactly face each other at the start. The queen is worth 9 points.
King - The king starts next to the queen. The king can move to one of the eight squares around it. It is limited as an active piece, but always is vulnerable to attack. No numerical value can be put on it.
A king may perform a special move known as "castling". This is when a king moves two spaces towards a rook, and the rook moves to the square on the other side of the king. This may not be done if:
Solanales
The Solanales are an order of flowering plants, included in the asterid group of dicotyledons. Some older sources used the name Polemoniales for this order.
British Rail Class 31
The British Rail Class 31 diesel locomotives, also known as the Brush Type 2 and originally as Class 30, were built by Brush Traction from 1957-62.
British Rail Class 33
The British Rail Class 33 also known as the BRCW Type 3 or Crompton is a class of Bo-Bo diesel locomotives ordered in 1957 and built for the Southern Region of British Railways between 1959 and 1963.
A total of 98 class 33s were built by the Birmingham Railway Carriage and Wagon Company, and they were called "Cromptons" after the Crompton Parkinson electrical equipment installed in them.
Like their lower-powered BRCW sisters (BR classes 26 and 27) their bodywork and cab ends were of all steel construction
The original (1957) number sequence was D6500–D6597.
British Rail Class 35
The British Rail Class 35 is a class of mixed traffic B-B diesel locomotive with hydraulic transmission. On account of their Mekydro-design hydraulic transmission units, the design became known as the Hymeks.
The type was developed for the Western Region of British Railways, which had opted for lightweight locomotives with hydraulic transmission when allocated funds under the British Railways Modernisation Plan of 1955. One hundred and one of the class were built between 1961 and 1964 when it became apparent that there was a requirement for a medium power diesel-hydraulic design for both secondary passenger work and freight duties.
They were allocated to Bristol Bath Road, Cardiff Canton and Old Oak Common. None of the class was named. Withdrawal from service began in 1971, and by 1975 all had been withdrawn. Their early withdrawal was caused, primarily, by BR classifying the hydraulic transmission as non-standard. Four examples survived into preservation.
British Rail Class 37
The British Rail Class 37 is a diesel-electric locomotive. It is also known as the English Electric Type 3. The Class was ordered as part of the British Rail modernisation plan.
