The new James Spooner will be the seventh locomotive to be built by the Ffestiniog Railway Company in its own workshops at Boston Lodge, and the seventh FR Double Fairlie. The building of the new locomotive was announced in 2016, with an anticipated completion date of 2020. It will be a replacement for Earl of Merioneth.

This locomotive takes its name from an earlier FR engine which was named after the company's first manager.

History[edit]

Design of new boiler for James Spooner

Announcement & Design[edit]

It was announced in March 2016 that Earl of Merioneth was worn out and needed replacement and that the new double engine would be named James Spooner. The power bogies for the new loco, and some cab fittings would come from Earl of Merioneth. The locomotive will feature a boiler the same as that which will replace Merddin Emrys' current boiler. This boiler will be built at Boston Lodge to a hybrid riveted/welded design. It is also planned that the locomotive will have a removable roof section, so it can be presented in the style of Merddin Emrys when new. It is planned the locomotive will be complete in 2020, in time for the 150th anniversary of Little Wonder's trials of 1870. At the time of the announcement some boiler components had been delivered.[1]

In December 2016 the Ffestiniog Railway Society distributed appeal leaflets with the magazine to raise money for the new loco. This leaflet featured the first concept drawing for the loco. At the same time it was stated that the appeal would help fund new components so that (with the exception of the power bogies) parts from Earl of Merioneth would not be needed and that James Spooner would be entirely new. This will additionally make it easier to restore Earl of Merioneth in the future.[2]

December 2016 also saw more boiler components, including the ready formed tapered barrels arrive at Boston Lodge.[3]

The design work on the new loco is being carried out with the aid of modern 3D solid modelling techniques. This work is being carried out remotely by a volunteer and was considered around 90% complete at the end of 2017. The use of digital modelling techniques allowed the design to be easily modified as it progressed with the result that the proportions of the final design could be adjusted to be more representative of historic practice.[4] The boiler design is such that it is the same overall size as the Hunslet boilers of Earl of Merioneth and Merddin Emrys and could be used to replace the boilers of those locos. The detailed design includes the successful taper shape used in David Lloyd George but with fireboxes more like those of the Hunslet boilers which have proved less prone to broken stays. The tube layout is also the same as the Hunslet boilers which are known to steam well and be more suited to coal firing than that of David Lloyd George. This will also allow the reuse of the superheater castings from the Hunslet boilers.[5]

Construction[edit]

Boiler construction commenced in January 2018, with major components being welded together by a contractor in the Tanat Valley.[6] By March the cradle was under construction at Boston Lodge.[7] In February 2019 it was reported that good progress had been made with the boiler and that it was expected to be delivered to Boston Lodge later in the Spring.[8] The chimneys had also been cast by this time, and are now in the top yard awaiting eventual fitting. The first of the assembled boiler barrels was delivered to Boston Lodge in March 2019.[9] Other pre-assembled components were expected to follow shortly in readiness for final assembly at Boston Lodge.[10] On the 20th March the carrier frame was fully assembled, thus (according to tradition) turning the collection of components into a locomotive for the first time.[11] Following the mounting of the frames on the bogies attention was turned to the completion of the reverser and brake linkages whilst the absence of a boiler made access easier.[12] By October 2019 the firebox had been assembled and one of the boiler barrels attached.[13]
