History in South Africa
The NG15 class of locomotives were developed for use on the 60cm gauge lines of SAR and were a development of previous classes of locomotive.
The origin of the design was the three locomotives of the Hd class built for the Otavi Railway in German South West Africa (now Namibia). Needless to say these locomotives were German built being constructed by Henschel & Sohn in Kassel. The design progressed in 1922 with a further six locomotives, again built by Henschel & Sohn, that became the NG5 class.
After trials of one of the locomotives on the Avontuur line the design was altered again to become what is now known as the NG15 class. The preceding classes made use of flangeless driving wheels on one set of the eight coupled driving wheels, however this still proved unsuitable for the tighter curves on the Avontuur line. Therefore what differentiated the NG15s from their preceding classes was the use of a Krauss-Helmholtz pony truck for the leading wheels. This system allows the front driving axle some sideways movement so that only the rear three axles form a rigid wheelbase. The front axle is guided around curves by the front pony truck to which it is attached via a pivoted linkage.
Preservation in the UK
133 arrived in the UK at the same time as 134 and was initially brought over from South Africa for a railway at Robin Hood's Bay in Yorkshire but this fell through and the locos were purchased for the WHR's future motive power back in 1998. Subsequently two NGG16s (87 and 130) imported for the same project made their way to the WHR.
To the WHR
After its arrival in Wales 133 was cosmetically restored and was displayed in the bay platform at Dinas for nearly 10 years. The loco was displayed in Caernarfon in 2009 as part of the effort to raise money for sister loco 134.
Eventually the weather had taken its toll and the boiler cladding was stripped to prevent further deterioration. the tender body was scrapped and the frames used to hold 134's new tender while its own frames are restored. The locomotive remains in the open at Dinas.
