ISAAC - Bagnall No. 3023 - was built in 1953 at a cost of £5,540 as an 0-4-2T 2 ft (610 mm) gauge loco, one of four Bagnall locos built for the South African Rustenberg Platinum Mine. The locos were numbered RPM 1 to 4, with 3023 being RPM number 3.
When the 2ft gauge track at Rustenberg was altered to 3' 6", the four narrow-gauge locos (all now preserved) became redundant.
Nos.3. and 4 arrived at Gelert's Farm Works on the Welsh Highland Heritage Railway In April 1982. Work was begun on both locos but resources weren't sufficient to complete the work on both.
In 2007 No. 3 was sold to a private purchaser and moved to Wakefield for further restoration work.
In June 2012 the loco was relocated to Boston Lodge Works to complete the restoration, arriving at Woody Bay 29 November 2013.

The Rustenberg Platinum Mine is a very large mining complex north-west of Johannesburg.
Whilst at Rustenburg, the four Bagnall locos underwent several modifications, including:
No. 1 - 2870/1948 Gold Reef City, Johannesburg
No. 2 - 2895/1948 Loxhill, Surry, England
No. 3 - 3023/1953 Resident at Lynton & Barnstaple Railway, North Devon.
No. 4 - 3050/1953 Resident at the Welsh Highland Heritage Railway, where in 1992 it was officially named 'Gelert'.
We are indebted to Andrew Goodwin, co-owner of Bagnall 3050 'Gelert' - the resident steam loco on the Welsh Highland Heritage Railway Porthmadog - for the above information.
