===Manchester Ship Canal===Built by the Hunslet Engine Company of Leeds in 1898, [[Whyte notation | 0-6-0T]] works number 686 was delivered new to the second of ten Hunslet ‘Chest’ class locomotives ordered by the Manchester Ship Canal Company(MSC). The locomotive It was originally named given the name “St John” after Port Saint John in New Brunswick, Canada.<ref>[[Bibliography#Books | Shaw (1998)]] p. 31.</ref>  The locomotive had a number of special features to enable it to work heavy trains round the tight curves of the MSC’s extensive railway network. These included Cartazzi leading axle boxes (see below) and flangeless centre driving wheels. Leaf springs were fitted on the front two axles and later numbered coil springs on the rear axle. In a powerful loco with a short wheelbase, this resulted in a lively dancing ride which led to members of the class being referred to as a ‘Jazzer’.<ref>[[Bibliography#Books | Shaw (1998)]] p. 27.</ref>  During the First World War the MSC stopped using locomotive names and introduced numbers, 686 becoming No 14.<ref>[[Bibliography#Books | Shaw (1998)]] p. 29.</ref> One name plate was retained and fixed on the rear inside of the cab, where it can still be seen today. <gallery>File:686_Name_Plate_20160713.jpg | ‘St John’ nameplate 686’s cab</gallery> During its working life with the MSC, 686 may have carried a number of different liveries, probably starting life in dark green with double white lining and possibly later acquiring a slate blue livery. The final livery was known to have been black (see gallery below).<ref>[[Bibliography#Books | Shaw (1998)]] p. 30.</ref>

686 was finally withdrawn from service by the MSC in 1962, and the following year was purchased by ICI Dyestuffs at Blackley Manchester. There a time when the locomotive railway was named “The Lady Armaghdale”, a name already carried by being scaled down due to the locomotive it replacedtransfer of traffic from rail to road.

===ICI Dyestuffs===In 1963 a locomotive at ICI Dyestuffs at Blackley Manchester was damaged in a runaway accident. The locomotive was a Hawthorn Leslie saddle tank No 3455/1920 named “The Lady Armaghdale” after the wife of a former Chairman of the company.<ref>[[Bibliography#Books | Shaw (1998)]] p. 35.</ref> Rather than repair the Hawthorn Leslie, the company opted to purchase 686 as a readily available working replacement. 686 was duly repainted in ICI crimson livery and acquired the name “The Lady Armaghdale”, although the locomotive was never popular at ICI, being regarded at best as a pseudo ‘Lady Armaghdale II’. By 1968, 686 had been withdrawn from service by ICI in 1968for a second time.<ref>[[Bibliography#Books | Shaw (1998)]] p. 36.</ref>

Following their acquisition of [[2047 Warwickshire | MW 2047 Warwickshire]] in 1967, 686 was the second locomotive to be purchased by the [[Warwickshire Industrial Loco Locomotive Preservation Group Trust | Warwickshire Industrial Loco Preservation Group]] in 1969, arriving on the Severn Valley Railway in on 14 July of that year1969.<ref>SVR Stock Book Ninth Edition</ref>

Since arrival, 686 has spent some time serving as ‘Thomas’ both It is allocated [[TOPS codes#TOPS_locomotive_classification_and_numbering|TOPS]] number 98186 and is one of three standard gauge locomotives have run on the SVR and elsewhere, including overseas. She has also appeared mainline that were not previously in film and TV productions including BR stock; for numbering it was assigned power class 1F on the basis of its tractive effort<ref>[[The Incredible Drhttps://en.wikipedia. Baldickorg/wiki/British_Rail_Class_98 British Rail Class 98 on Wikipedia]]. Although not sufficiently powerful to haul service trains, 686 has from time to time acted as 'station pilot' and shunter(Retrieved 12 September 2023)</ref>.

1998 marked the centenary of HE ===First boiler ticket===686. The locomotive began the year as was first steamed a roving ‘Thomas’ and was photographed by David Cooke at week before the East Lancashire Railway in May of that year 1969 August Gala,<ref>[[Bibliography#Books | Shaw (see gallery1998)]] p. By October39.</ref> although SVR News does not record any mileage until 1971. Not sufficiently powerful to haul service trains, 686 had been repainted in the more appropriate livery of Manchester Ship Canal No 14 acted as 'station pilot' andshunter, as part hauled a number of the celebrationsworks trains and gave occasional footplate rides at Bridgnorth. The locomotive also appeared in several film and TV productions, re-visited the East Lancashire Railway (see gallery) including a BBC Horizon documentary on railway accidents in the county where she first worked 1972 and the Middleton Railway as a Russian locomotive in [[The Incredible Robert Baldick]] in Leeds, the city where she was builtsame year.

Once again boiler issues brought a premature end to service for 686 at the end of 1999. The mileage recorded in SVR News was as follows:{| class="wikitable"! <b>Year</b> !! style="text-align:right;" | <b>Mileage</b> |-| 1994 || style="text-align:right;" | 656|-| 1995 || style="text-align:right;" | 1,219|-| 1996 || style="text-align:right;" | 821|-| 1997 || style="text-align:right;" | 1,424|-| 1998 || style="text-align:right;" | 1,692|-| 1999 || style="text-align:right;" | 1,085|-| <b>Total</b> || style="text-align:right;" | 6,897|-| <b>Cumulative</b> || style="text-align:right;" | 8,050|} ===Fourth boiler ticket===A quick overhaul was carried out allowing a return to steam by 2001. 686 resumed duties as ‘Thomas’ in 2002, again [[SVR-based locomotives visiting other events|visiting many railways in the UK and also making overseas visits to Holland (Z.L.S.M.) and Germany (Krefeld) in 2005]]. After being withdrawn from service in September 2009, once again with boiler issues, 686 was cosmetically restored at Bridgnorth into ICI red livery as 'The Lady Armaghdale'. The locomotive then entered [[The Engine House]] on 18 October to be displayed while awaiting overhaul.<ref>SVR News 171</ref> She briefly left The Engine House on a few occasions, in March 2012 to visit the NEC (Best of Britain Exhibition) and again briefly in June 2018 and March 2019 during shunts of displayed locomotives. In July 2019 she was extricated from [[The Engine House]] and transported from Bridgnorth for display at the Chateau Impney Hill Climb Motorsport event. The locomotive again left the Engine House in June 2021 in order to create space for a 'Staycation' event, 'temporarily' moving to [[Kidderminster Carriage Shed]].<ref>[https://wilt.jimdo.com/7b-0-6-0t-he686-of-1898/ WILT]</ref> In the event it continued its storage there, occasionally appearing on display, such as at Kidderminster during the 2023 [[Christmas services]]. <gallery>File:Hunslet.jpg | 686 having arrived at Holland for a 'Thomas' event in October 2002 - the first SVR locomotive to go abroad (David Cooke)686_20190707.jpg | 686 at Bridgnorth in July 2019 awaiting delivery for display at the Chateau Impney Hill Climb Motorsport event</gallery> The mileage recorded in SVR News to 2004 was as follows (details for 2005-2009 were not published):{| class="wikitable"! <b>Year</b> !! style="text-align:right;" | <b>Mileage</b> |-| 2001 || style="text-align:right;" | 11|-| 2002 || style="text-align:right;" | 2,293|-| 2003 || style="text-align:right;" | 1,937|-| 2004 || style="text-align:right;" | 2,272|-| <b>Total to 2004</b> || style="text-align:right;" | 6,513|-| <b>Cumulative to 2004</b> || style="text-align:right;" | 14,563|} ==Cartazzi axleboxes==F. I. Cartazzi was a senior engineer of the Great Northern Railway. His modified axlebox design was intended for trailing carrying wheels on larger locomotives and was used extensively on LNER ‘Pacific’ steam locomotives.<ref>[https://en.wikipedia.org/wiki/Cartazzi_axle Wikipedia]</ref> On 686 his system is used on the leading axle. The top of the axlebox and underside of the axlebox lid have a series of inclined faces. On sharp curves the axlebox is forced sideways, bringing different faces into contact with the lid. On leaving the curve, the weight of the locomotive transmitted through the bearing spring and axlebox lid provides a self-centering force. The leading connecting rods on 686 include an additional horizontal pivot in front of the centre driving wheel to cater for the lateral movement of the front wheel, a feature not necessary on similar locomotives with normal axleboxes such as Jinty 47383. <gallery>File: 686_20160723.jpg | 686 coupling rods with horizontal pivot in leading rod (right)File: 47383_20160723.jpg | 47383 coupling rods for comparison</gallery> ==See also==[[Steam Locomotives]]<br>[[SVR-based locomotives visiting other events]]<br>[[TOPS codes]]<br>[[Locomotive numbering|Locomotives running under different identities]] ==References and sources==<references />
