"The railway does a tremendous amount for the town. The last time the trains stopped running, in 2000, an awful lot of shops closed. If we stopped running a lot of shops would close again."
The volunteer shortage also meant Mr Bradshaw couldn't get time off - he'd have dearly loved to go to the miniature train convention in Whangarei earlier this month but couldn't - and if he fell ill the trains would grind to a halt.
A fireman shovels coal, checks water levels and steam pressure, and keeps an eye out at left-hand corners: "The fireman's the driver's second pair of eyes."
The role took about four trips to learn and was not arduous, even though the 1927 steam locomotive Gabriel used half a tonne of coal a day.
"We've had little old ladies do it. We used to have a family where the mother, who was in her 50s, was the fireman, the father was the guard and the daughter was the driver."
Volunteering as a fireman was a step to becoming a diesel driver, led to new skills and unit standards, and looked good on a job-seeker's CV.
Trust chairman Johnson Davis said the railway had volunteers from Kaikohe, Kaitaia, Kerikeri, Mangonui, Okaihau, Rawhiti and Whangarei - but none from Kawakawa, despite a leaflet drop calling for fresh helpers. Four hundred flyers were distributed without one response.
The Advocate understands the town has 147 able-bodied adults on the unemployment benefit.
The trains run four times a day during the summer holidays, taking passengers on a 10km return trip to Taumarere and Kawakawa is one of the few places in world where trains run down the middle of a state highway.
The railway carries more than 10,000 passengers a year. That number is expected to skyrocket once the tracks are restored all the way to Opua. The trains are also essential to the future of two other projects: the Twin Coast Cycle Trail, which aims to link up with the railway for the Kawakawa-Opua leg, and the restoration of the 101-year-old steam ferry Minerva, which could also connect with the railway once it reaches Opua.
-The railway is also looking for painters, gardeners, guards and drivers.
