|SHR Criteria a)|
|Locomotive 1308 has historical significance because;
It associated with the operation of suburban passenger service in Sydney.
It demonstrates the motive power available to the NSWGR at the turn of the twentieth century.
Its conversion at Eveleigh Workshops from an earlier configuration to a tank locomotive demonstrates the capability and engineering expertise of the railway workshops at this time.
|SHR Criteria c)|
|The locomotive has aesthetic significance because;
It demonstrates the design and style of a locomotive of the late Victorian era.
It demonstrates, following conversion to a tank engine, an early attempt to develop a ‘family’ appearance for NSWGR locomotives.
It demonstrates a certain elegance, with the tall chimney, high wheels, raked running plate and long slender side tanks.
|SHR Criteria d)|
|Locomotive 1308 has social significance because;
It is associated with a number of former tramways and rural branch lines.
It is held of value to the Rail Transport Museum as evidenced by its initial retention.
|SHR Criteria e)|
|The locomotive has technical significance because;
It demonstrates the popular trends in British railway practice of the day. Progressive for NSWR yet conservative British standards, the class incorporated many design features of the earlier tank locomotives of London’s Metropolitan Railway from 1865. Round top boilers with Salter safety valves (later replaced with the Ramsbottom type), driving wheels at 5’4, four inches smaller then the English counterparts provided higher tractive effort for the rougher more steeply graded permanent way standards of the NSWGR, and fortuitously more suitable for suburban service. It demonstrates use of the Webb radial trailling ruck, ver rare in Australia.
It also demonstrates the conservatism of the NSWGR at the time of conversion to a tank engine, the critical design parameters of the now Z13 class, were archaic.
It demonstrates by its longevity the extremely well engineered nature of the original design and the skill of those who maintained it over the years in service
|SHR Criteria f)|
|The locomotive has rarity value because;
It is an example of an early form of motive power for the Sydney suburban network.
It is an example of an early tramway locomotive, crewed by a driver only, one of only three in existence.
It is in a unique position to interpret the operation of the Loop line, with which it was so strongly related
|SHR Criteria g)|
|The locomotive has representative value because;
It is representative of the group of 20 C79 (Z12) class tender engines converted by Eveleigh Workshops into tank locomotives for the Sydney suburban system
It is representative of the class of engines used for many years on tramways and branch lines.
