143 is an NGG16 Garratt locomotive that that is currently in use on the Welsh Highland Railway.

History in South Africa[edit]

143 was built by Beyer Peacock of Manchester for South African Railways to their 2-6-2+2-6-2T NGG16 Garratt design. This loco was one of the fourth batch of seven NGG16s (no.s 137 - 143) built in 1958. These were the last steam locos built by Beyer Peacock, which were originally ordered by the Tsumeb Copper Corp of South West Africa in 1958 but when its line was altered to Cape Gauge, South African Railways took over the order. It carries the works number 7868.

Although not first placed on the 93 mile long Ixopo branch (from Umzinto to Ixopo / Donnybrook), according to the November 1965 Natal System locomotive returns, 140 and 143 were in service on the branch at that time (together with No.s 85, 86, 112, 113, 114, 115, 126, 129, 131 and 139).

Preservation on the WHR[edit]

143 was obtained from the Alfred County Railway who overhauled the loco before shipping it to the UK. It arrived at the FR in January 1997. It entered service on the WHR(C) in September 1998, after receiving boiler attention. Its first livery on the WHR was SAR black. As the last Beyer-Garratt built by Beyer Peacock, it makes an interesting stablemate of the pioneer of the type, K1.

Problems with a crack in a fly crank stopped the engine just before peak season in 2008. As an emergency measure the hind bogie from 138 was substituted.

143 entered its 10 year overhaul at the end of 2009 at Dinas, with parts being moved to Boston Lodge. The boiler from 140, and the hind bogie were used in the overhaul. Converted back to coal firing, with a number of improvements after experience with No 87, including a larger ashpan, and in-cab ashpan drench control, 143 was finished in July 2011, entering service with a 'GWR Green' livery.

At the end of the 2014 Season, 143 was stripped down for a major overhaul of the power bogies. When the locomotive was stripped and assessed, it was found that it needed much more work to get to our current standard than what was first anticipated.

As a result, 143's year and a half overhaul resulted in it having the most comprehensive overhaul that a NGG16 has had at the WHR. Many components were replaced with new, these included the suspension links, springs, horn cheeks, horn keeps, rod end bushes, all of the bushes in the valvegear and pony trucks. There was much more work done to renew worn components. An issue that we did not anticipate was that the rear frame stretcher on the front unit had worked itself loose. This was a critical component as it held the frame plates in place and also held the pony truck in place.

Following the completion of these heavy repairs, 143 returned to service in May 2016.
