The 40 class was the first mainline diesel-electric loco in NSW.
They
began with mainline services, but later worked on passenger services.
One
problem was the A1A-A1A axle arrangement, this causing wheel wear.
Later
on, two units were sold to Robe River
for construction work.
Robe
River:
Once bought by Robe River, these two locos were converted to a Bo-Bo
wheel arrangment (to improve their performance) before being used for
construction work on the Pannawonica line, as well
as shunting, for a while.
