As early as 1975, railway enthusiasts in the United Kingdom began building new steam locomotives. That year, Trevor Barber completed his gauge locomotive "Trixie" which ran on the Meirion Mill Railway. From the 1990s onwards, the number of new builds being completed rose dramatically with new locos completed by the narrow-gauge Ffestiniog and Corris railways in Wales. The Hunslet Engine Company was revived in 2005, and began building steam locomotives on a commercial basis. A standard-gauge LNER Peppercorn Pacific "Tornado" was completed at Hopetown Works, Darlington, and made its first run on 1 August 2008. It entered main line service later in 2008, to great public acclaim. Demonstration trips in France and Germany have been planned. over half-a-dozen projects to build working replicas of extinct steam engines are going ahead, in many cases using existing parts from other types to build them. Examples include BR Class 6MT "Hengist", BR Class 3MT No. 82045, BR Class 2MT No. 84030, Brighton Atlantic "Beachy Head", the LMS "Patriot 45551 The Unknown Warrior" project, GWR "47xx 4709, BR" Class 6 72010 Hengist, GWR "Saint" 2999 Lady of Legend, 1014 "County" of Glamorgan and 6880 Betton "Grange" projects. These United Kingdom based new build projects are further complemented by the new build Pennsylvania Railroad T1 class No. 5550 project in the United States. The group’s original goal was to surpass the steam speed record held by the LNER Class A4 4468 Mallard when the 5550 is completed. However, that goal was soon dropped, and now they just plan for the 5550 to fill in a huge gap in preservation.
