F&WHR set to test Fairlies, Garratts and Mallets in head to head contest

Not only is Manning Wardle replica 2-6-2 Lyd due to appear in authentic Southern livery for the first time, but NG/G16 number 143 will return from major overhaul in its new green livery, popular Hunslet 2-4-0 Linda will steam again and visiting locos already confirmed include Adrian Shooter's Darjeeling Himalayan 19B, Chaloner, a vertical-boilered DeWinton and, for the first time, a two-foot gauge Mallet.

"2011 looks set to be a golden year for the Welsh Highland Railway," says F&WHR General Manager Paul Lewin. "Not only will the full 25 mile line be officially opened on April 20, but we are eager to bring a wide variety of locos to be put through their paces on the UK's most demanding railway.

"For the first time, visitors will be able to see three different types of articulated locomotives working together - The FR's Double Fairlies; K1, the world's first Garratt; NG/G16 143, the last Garratt to be built by Beyer Peacock in Manchester; and Statfold Barn's Jung Mallet, No. 9. For the first time, these different loco designs can be seen competing in against each other to see who really is King of the Hill."

Statfold Barn's Mallet 0-4-4-0T, Jung works No. 4878, was delivered to H. E. Oving of Rotterdam, Netherlands in April 1930 for use on the Jatibarang Brebes Sugar Mill Railway in Indonesia , where it carried No. 9. The Sugar Mill was built in 1842 by the government of the Dutch East Indies colony.

The loco is now approaching completion and is scheduled to undergo test runs before Christmas. The first time the public will be able to see her in action will be March 19th, after which the loco will move to Porthmadog.

Says Statfold Barn spokesperson Henry Noon: "Graham Lee and the team at Statfold Barn Railway are all very excited at the prospect of our latest rebuild project visiting North Wales. It will be an ideal opportunity to see just how the loco will perform on what is undoubtedly a challenging line.

"We believe this is the first time a Mallet has run in Britain on a public passenger carrying railway and it is apt that it should be on the F&WHR where articulated power is the norm!"

The loco weighs 17 tonnes and is expected to offer performance approaching that of a Double Fairlie, although the loco will undergo exhaustive testing during its stay in North Wales to see exactly what it can do. In Indonesia, the loco burnt sugar cane for fuel, but will be coal fired in the UK.

"The Mallet has been overhauled to Statfold's usual high standard in close cooperation with Ffestiniog engineers," adds Lewin. "Wheelsets have been gauged and profiled to meet FR specifications and the loco has been fitted with vacuum brakes and chopper couplers to make it suitable for passenger use."

The Mallet design has a rigid main frame that supports the rear end of the boiler. At the front of the main frames are the high-pressure cylinders. A sub-frame, carrying a second set of driving wheels powered by low-pressure cylinders, is positioned ahead of and pivoted to the main frames. Exhaust steam from the high-pressure cylinders is carried to the low-pressure cylinders through flexible steam pipes, as is the exhaust steam from the low-pressure cylinders to the blast pipe in the smoke box. The overall result is a compact but powerful locomotive able to negotiate tight curves.
