The discovery of a broken side control spring on G42’s hind engine unit was soon followed by the dawning realisation that with the engine facing the ‘Down’ direction – towards Gembrook, as all our engines do – the workshop wasn’t long enough to get the pony truck in question over the drop-pit in the workshop.
Above, a rare photo of G42 – facing the “wrong” direction – poking out from behind the new boiler of NG/G16 129, and below, the pony truck suspended in mid-air over the drop-pit whilst the spring is replaced. The new spring awaits fitting (above).
Note the design, with one spring inside another; the original spring design and material section would be prohibitively expensive to replicate today, so we have achieved the same result using two springs of different diameters.
