The first steam locomotive commissioned to be built by the revived Corris Railway was a modern version of the Kerr Stuart “Tattoo” class locomotive, similar to locomotive No. 4 (now Talyllyn Railway No. 4 “Edward Thomas”). The Project was started officially on 1st February 1995 and with funding provided by members’ covenants plus many other fund raising initiatives. The new locomotive, numbered 7, entered service on 20th August 2005, bringing the sound of a steam engine at work back to the Dulas Valley after half a century.
Over the last two decades No. 7 has proved a reliable locomotive. Since the last “10 year” overhaul she has completed 3,978.5 miles, primarily on Corris metals, although this figure does include a couple of hundred miles working from Tywyn to Nant Gwernol on the Talyllyn Railway. No. 7 has suffered only one major failure whilst working Santa Trains in December 2018, that being whilst taking empty coaching stock back to Corris station to collect extra passengers when lubrication starvation caused a section of the valve gear on the driver’s side to seize. As the locomotive was working uphill with the regulator open this caused stress and damage to the valve gear as a whole. The locomotive was taken out of traffic immediately and repairs were carried out with the help from the Vale of Rheidol Railway. The “Tattoo” was ready just in time to work a photographic charter and a “Your Railway for the Day” experience package before passenger train services for 2019 were due to commence at Easter.
2025 marks the 20th year of service on the railway for No. 7 and the second “10 year” major overhaul of the locomotive is now well underway. An entirely volunteer force started the strip down of the locomotive between Christmas and New Year 2024.The same team will return between Christmas and New Year 2025 to start putting the locomotive back together.
During the summer the boiler was retubed and repainted at Maespoeth and has passed hydraulic testing. Hot testing will take place once the boiler is back between the frames. The frames were cleaned and repainted and the gauges were all sent away for re-calibration.
Alan Keef have reprofiled the wheels and fitted new crank pins and will be supplying a new stainless steel smokebox for the loco. It is hoped that the locomotive will be substantially complete by the New Year so that No. 7 can return to service in time for Easter 2026.
Therefore, this year No. 10 the second “new build locomotive”, which was delivered to the Corris Railway on 30th August 2023, will be at the head of the Santa Specials for the first time after Storm Darragh caused the cancellation and total loss of the 2024 Santa Trains. There are four trains scheduled to run on December 13th and 14th, leaving Corris at 11.00am, 12.30pm, 2.00pm and 3.30pm. Fares are £10.00 for adults and £12.50 for children. With 70 seats available on each train early booking is advisable, particularly if planning your day around a particular train time. Booking is available via www.corris.co.uk/tickets The last opportunity to see No. 10 in 2025 will be Saturday the 27th December where she will be hauling a series post-Christmas afternoon services.
