    Collection of photos of Thompsons A2/1 class pacifics

    The London and North Eastern Railway (LNER) Thompson Class A2/1 was a class of 4-6-2 steam locomotives built at Darlington locomotive works during 1944. They were originally ordered as Class V2 locomotives, as designed by Sir Nigel Gresley, but were revised during construction into a 4-6-2 'Pacific' arrangement under the instruction of Edward Thompson.
    At the time Edward Thompson succeeded Sir Nigel Gresley as Chief Mechanical Engineer of the LNER in April 1941, Darlington works was busy building Class V2 mixed traffic locomotives. Although the V2 class were competent and powerful locomotives, Thompson did not like this design as it required more servicing than his own mixed traffic B1 class 4-6-0. He also envisaged a time when the V2s would be replaced by his own design of 'Pacific' locomotives, but would not receive authority to build a new class during the war. He therefore decided to build the final four V2 already authorised as experimental 'Pacific' locomotives along similar lines to his recently rebuilt A2/2 class. The revised design was authorised in August 1943 and the new locomotives built between May 1944 and January 1945.
    The pony truck of the V2 class was replaced by Thompson's own design of bogie and they had an extended smokebox. They retained the same boiler as the V2 class although the pressure was increased to 225 psi, giving an increased tractive effort of 36,390 lbf (161.87 kN). The firebox was also the same as the V2 although these were the first LNER locomotives to be fitted with a rocking grate and ashpan. Rather than have all three cylinders driving a single axle Thompson adopted divided drive with the middle cylinder driving the first pair of driving wheels and the outside cylinders the middle pair. Thompson also abandoned the Gresley conjugated valve gear and instead fitted independent sets of Walschaerts valve gear to each cylinder.
    The four locomotives of this design performed adequately but proved to be under-boilered for their size and lacked adhesion. They were less problematic than the A2/2 class, but did not distinguish themselves

    Collection of photos of Thompsons A2/2 class pacifics

    The London and North Eastern Railway Class A2/2 was a class of six 4-6-2 steam locomotives rebuilt by Edward Thompson in 1943 and 1944 from his predecessor's P2 Class of 2-8-2 express passenger locomotives. The rebuilds were not particularly successful and all were withdrawn and scrapped between 1959 and 1961.
    On taking up office as chief mechanical engineer of the London and North Eastern Railway in April 1941, Edward Thompson proposed an unstreamlined mixed traffic version of Nigel Gresley's A4 Class Pacifics with 6 ft 2 in (1.880 m) driving wheels, but new construction would not have been authorised at this time. He therefore rebuilt the six of his predecessor's 2-8-2 P2 Class express passenger locomotives as Pacific locomotives to try out his own thoughts on their design. The P2 Class 2-8-2s had been built between 1934 and 1936 for service between Edinburgh and Aberdeen and had proved to be powerful and capable locomotives. However, the long fixed wheelbase was not ideally suited to the winding route, giving rise to maintenance problems on both the track and the locomotives, notably failure of the crank axle. Contrarily, O. S. Nock stated that the P2 class 'rode easily and elegantly around the sharpest curves. In either event, rather than transfer the locomotives to other duties on the East Coast Main Line south of Newcastle, where this would have been less of a problem, Thompson saw this as a chance to try out his own ideas of locomotive design.
    The pony truck and front coupled wheels of the original design were replaced by a newly designed bogie. The boiler barrel was shortened by 2 ft 0.25 in (0.616 m) and a new front end was designed with 20 in × 26 in (508 mm × 660 mm) cylinders. Rather than have all three cylinders driving a single axle Thompson adopted divided drive with the middle cylinder driving the first pair of driving wheels and the outside cylinders the middle pair. However, In order to retain the original three connecting rods of the same length, the outside cylinders were set back behind the bogie, giving the locomotives an ungainly appearance. Thompson also removed the Gresley conjugated valve gear and instead fitted independent sets of Walschaerts valve gear to each cylinder. The first locomotive to be rebuilt at Doncaster Works was No. 2005, Thane of Fife, which was ordered in October 1942 and completed in January 1943. After trials the remaining five P2 locomotives were ordered to be rebuilt in September 1943 and they all appeared in traffic during 1944.
    The new design steamed well and retained much of the power of the P2's. The reduced weight meant they had a high power to weight ratio, and were good at hauling high speed expresses, although in the opinion of Nock, they "acquired a particularly bad reputation for wild and unsafe riding at high speed. However, there were other problems which prevented them from ever making an impact on the east coast main line. The first of these was a lack of adhesion causing wheel slip when starting, which meant that they could not be used on the Edinburgh-Aberdeen line for which they had originally been built. The second problem was that of reliability caused by their having been adapted from quite different locomotives. Both the A2/2 and the subsequent A2/3 suffered badly from frame movement, vibration and loose fittings. Using equal length connecting rods, as well as the divided drive meant that the centre cylinder was much further forward than the outside cylinders. During their lifetime in service Earl Marischal was the only A2/2 to cover over one million miles, 360,907 as a P2 and 673,947 as an A2/2. The
    Withdrawals from stock began in 1959 starting with 60505 Thane Of Fife on 10 November that year. The next A2/2 to be withdrawn was Lord President on 27 November. 60501 Cock o' the North was withdrawn in 1960, while 60504 and 60506 were withdrawn in 1961, with 60502 the last member of the class withdrawn on 3 July that year.

    Collection of photos of Peppercorn A1 Pacifics

    The London and North Eastern Railway (LNER) Peppercorn Class A1 is a type of express passenger steam locomotive. Forty-nine original Peppercorn Class A1s were built to the design of Arthur Peppercorn (who was the last Chief Mechanical Engineer (CME) of the LNER) during the early British Railways era, but all were scrapped with the discontinuation of steam, with none of the original production run surviving into preservation. In 2008, a brand new 50th Peppercorn A1 locomotive, 60163 Tornado, was completed. Most of the former LNER Class A1 locomotives designed by Sir Nigel Gresley had been rebuilt as LNER Class A3 locomotives prior to this class being conceived. The few straggling LNER Class A1 locomotives that remained unrebuilt during the tenure of Peppercorn's predecessor, Edward Thompson, were redesignated by him as Class A10s in preparation for the construction of his new Class A1 locomotives. Thompson rebuilt the pioneer LNER Pacific Great Northern in 1945; originally this was the new Class A1, but the rebuild was not repeated. Instead, initiated by Thompson but largely taken forward by his successor Arthur Peppercorn, Great Northern was designated Class A1/1, and a new class of Peppercorn A1s ordered.
    The locomotives were designed to cope with the heaviest passenger trains in the post-war period on the East Coast Main Line (London – York – Newcastle – Edinburgh – Aberdeen) which consisted normally of trains with up to 15 coaches and up to 550 tons. The Peppercorn A1s were able to pull such a train on the flat at a speed of 60–70 mph (95-110 km/h). The class used a double Kylchap chimney system and, like previous LNER Pacifics, had a 3-cylinder arrangement.
    The new A1s were ordered by the LNER but were delivered after the LNER had been nationalised to form part of British Railways at the start of 1948. The 49 engines were built at the Eastern Region's Doncaster and Darlington works between 1948 and 1949.

    Apologies as I now see that this is a northbound service approaching Peterborough North. Part of the confusion is that Neil often misses out the local portion of the location (e.g notes Peterborough but fails to identify whether North or East as applicable. I haven't traversed the East to North link since 1959 since when a few changes changes have occurred hence not recognising the yard which is now the stabling sidings for EMUs.
