This Locomotive was built by John Fowler and Company Leeds England in 1925 maker’s number 16342. It was built to an order for the Napier Harbour Board along with sister engine 16343. They were numbered by the Napier Harbour Board 5 and 6 respectively. They were used out breakwater construction and shunting duties at the Harbour. One loco being used on the breakwater and the other in shunting service as a general rule.

Number 5 survived the Napier earthquake after it was buried up to the cylinders by a large slip from Bluff Hill. A later photo reveals that the loco was dug out by hand. The rest of the Fowler's life was more mundane being based on the breakwater for its last few years. It is understood that an incident during this work which damaged the piston cover resulted in the loco being withdrawn from service. Number 6 which was in better mechanical condition was transferred to the breakwater and number 5 laid up. It had a few parts removed for use on number 6 while it was stored.

The Wellington Branch of the New Zealand Railway and Locomotive Society (later Silver Stream Railway) made attempts to purchase both locomotive but at first the Napier Harbour Board refused to release them. Later in 1971 tenders were called for the 2 locomotives and Silver Stream Railway were the successful tenderer for #5. Number 6 was sold to the Tokomaru Steam Museum where it remains to this day. At first #5 was moved to Tokomaru were it was stored before a decision was made on its future. Early on it was thought that #5 would become a parts supply for #6. Fortunately this never happened and #5 was trucked to the Seaview storage site a few years later. It was moved again by road to the Silverstream Site in 1980 where it was stored mostly outside for the next 23 years.

A long time member of Silver Stream Railway, Bryan Bishop expressed his concern to the SSR Committee, at the condition of the locomotive that appeared to have no future with the railway, and expressed his desire to purchase and overhaul the locomotive to running order. The committee agreed and the locomotive was removed from its long term resting place and stripped for overhaul. Years of salt spray and outdoor storage had taken its toll on the locomotive with the cab and tanks fit only for scrap. The boiler had not faired any better with 2 holes in the barrel under where the sand domes had been fitted. Also the firebox had suffered the same problem. The boiler was moved to a boiler specialist in Wanganui who striped the tubes and inner firebox. Apart from the thick layer of scale the inside appeared in good condition. The striped boiler was later moved to Napier Engineering for completion.

The barrel was fitted with new steel where the domes had rusted it through and the outer and inner fireboxes had extensive surgery. The front tube plate was also repaired before new tubes and internal steam pipes were fitted. It was returned to the locomotive frame in March 2008. The Chassis of the locomotive had survived the years of storage far better requiring only minor repairs. New side tanks, coal bunkers and a cab were fabricated and fitted. The loco was steamed for the first time since 1960 on Queens Birthday weekend 2008 and entered service on the Silver Stream Railway in July 2008. It is currently in service but is due for work on its axle boxes and motion work in the short term.
