spindle had to be parallel with the outside ones from which it derived its motion. This problem had been overcome by what Holcroft called a "twist in the ports" (the passages that carried steam in and out of the cylinders). A consequence was that the length of these passages was greater than that generally recommended, increasing "dead space", and this was combined with a shorter exhaust passage. The net result would be rather different working conditions in the middle cylinder from those on the outside. A contributing problem was that any elongation of the outside valve spindles was multiplied by the conjugated valve gear. Although this had been anticipated at the design stage, the overall consequence was that the inside cylinder had a tendency to give more power than the other two as speed increased, leading to the overloading of the inside connecting rod bearings, especially the big-end which was liable to overheat and fail. Various experiments were tried over the years to cure this chronic ailment, and it was only towards the end of the steam era that a real solution was found in Great Western methods of lubrication and manufacture for the big-end bearing. Other problems persisted, such as a stiff, insensitive regulator and overall design flaws that hampered maintenance.

1059: 49: 1125: 1121:; excessive 'play' led to so much over-travel of the middle valve, that it began to hit the end-covers. In order to prevent this, when applying the gear to the Pacifics, Gresley fell back on the expedient of shortening valve travel even though that choked the exhaust at speed, was responsible for the heavy coal consumption, and negated most of the advantages gained by the locomotive's revolutionary design. However, by incorporating the Great Western-inspired valve modifications, the economies in coal and water consumption achieved were such that the 180 psi Pacifics could undertake long-distance non-stop runs that were previously impossible. 1035:(LMS) due to poor visibility; this included the modification of the upper smokebox area surrounding the chimney. Originally the whole smokebox wrapper was retained in order to form an air duct, with the exit behind the chimney, but this was found ineffective. The next stage, at least with 2751, was to cut off the top part of the wrapper, but retaining the sloping plate that directed air flow upwards, and therefore lifting the smoke above the locomotive. The original chimney was replaced by a double stove-pipe variety, and miniature deflector plates were added on either side, angled to concentrate the air flow when the locomotive was on the move. 1622: 961:

brakes to work trains formed of ex-NER coaches. Accordingly, fifteen (nos. 2568–82) of the forty A1s ordered by the LNER in 1923 had dual Westinghouse and vacuum brakes for the train – on these, the locomotive brakes were Westinghouse. In 1928, the LNER decided to standardise on the vacuum brake, and as the number of Westinghouse-braked coaches subsequently decreased, the need for Westinghouse-braked locomotives also fell. The fifteen A1s with Westinghouse brakes were converted to vacuum brakes between 1933 and 1935.

1213: 1699: 706: 973:. This locomotive appeared in August 1928 with 220 psi (1.52 MPa) boiler, 19-inch (483 mm) cylinders, increased superheat, long-travel valves, improved lubrication and modified weight distribution. Another new development was the changeover from right- to left-hand drive, less convenient for a right-handed fireman, but more so for sighting signals, resulting in the modification of all earlier locomotives. 1739: 1136:

locomotives greater speed potential, and the proof of this came in 1933 when a high-speed 3-car diesel railcar service had been mooted. As this would have provided limited accommodation for passengers, it was proposed to use steam traction at similar service speeds with six carriages. A trial return run between London and Leeds was made with modified A1 locomotive number 4472,

985:. The last nine A3 Pacifics were constructed with the device in 1935, and it became a standard fitting on all LNER large, wide-firebox boilers that were applied to new locomotives until 1949, except for a short period while Edward Thompson was CME. The banjo dome was one of the Gresley features he disliked. It was also applied to replacement boilers on the A3s. 844:. Gresley was appointed Chief Mechanical Engineer of the new company, which was the second largest of the "Big Four" railway companies in Britain. Realising the need for standardisation, Gresley adopted his GNR Pacific design as the standard express passenger locomotive for the LNER main line, designating it 'A1' within the 1497:. The driver and fireman survived with minor injuries although the locomotive and tender were buried under the four following coaches. 35 other passengers and railway crew were killed in the accident. As Class A3 locomotives were still in production at the time, a replacement was built with the same name and number. 1117:, which was the first to have the standard Gresley conjugated motion combined with long valve travel. However, practical problems were experienced with components quickly suffering from premature wear, especially in the main bearing of the large 2:1 lever which had not yet been fitted with the very necessary 1113:) over the 105 miles (169 km) from London to Grantham at an average speed of 51.8 miles per hour (83.4 km/h). However this was at the cost of heavy coal consumption, and general performance was well below the ultimate potential of the design. This was largely due to a regression from the earlier 1224:

The Gresley 3-cylinder drive arrangement continued to bring a number of practical problems, the root of which was probably the need for the inside cylinder to be steeply inclined in order to give space for the inside connecting rod to clear the leading coupled axle; at the same time, the inside valve

Most of the locomotives built as class A1 (also all of those built as class A3) had vacuum brakes for both locomotive and train. However, the LNER had inherited a substantial amount of Westinghouse-braked coaches, mainly from the NER, and it was necessary to provide some locomotives with Westinghouse

1228:

In spite of all this and the introduction of more recent Pacifics, in the middle of the 1950s Gresley types continued to have a quasi-monopoly of East Coast Main Line express passenger services, and as the Sixties approached they went through yet another series of improvements comparable to those of

Gresley's initial Pacific project of 1915 was for an elongated version of the Ivatt Atlantic design with four cylinders. Finally realising that he was in a design impasse, he took as a model the new American Pennsylvania Railroad class K4 Pacific of 1914. This in turn had been updated from a series

The first and most spectacular outcome occurred in 1928, when the Pacifics were called upon daily to work the Flying Scotsman train non-stop over the 392 miles (631 km) between London and Edinburgh. Initially three A1s and two A3s took turns on this service. The modifications also gave the A1
